<h1>NAME</h1>
<p>xsd - W3C XML Schema to C++ Compiler</p>
<h1>SYNOPSIS</h1>
<dl id="synopsis">
<dt><code><b>xsd</b> <i>command</i> [<i>options</i>] <i>file</i> [<i>file</i> ...]</code></dt>
<dt><code><b>xsd help</b> [<i>command</i>]</code></dt>
<dt><code><b>xsd version</b></code></dt>
</dl>
<h1>DESCRIPTION</h1>
<p><code><b>xsd</b></code> generates vocabulary-specific, statically-typed
C++ mapping from W3C XML Schema definitions. Particular mapping to
produce is selected by a <code><i>command</i></code>. Each mapping has
a number of mapping-specific <code><i>options</i></code> that should
appear, if any, after the <code><i>command</i></code>. Input files should
be W3C XML Schema definitions. The exact set of the generated files depends
on the selected mapping and options.</p>
<h1>COMMANDS</h1>
<dl id="commands">
<dt><code><b>cxx-tree</b></code></dt>
<dd>Generate the C++/Tree mapping. For each input file in the form
<code><b>name.xsd</b></code> the following C++ files are generated:
<code><b>name.hxx</b></code> (header file),
<code><b>name.ixx</b></code> (inline file, generated only if the
<code><b>--generate-inline</b></code> option is specified),
<code><b>name.cxx</b></code> (source file), and
<code><b>name-fwd.hxx</b></code> (forward declaration file, generated
only if the <code><b>--generate-forward</b></code> option is
specified).</dd>
<dt><code><b>cxx-parser</b></code></dt>
<dd>Generate the C++/Parser mapping. For each input file in the form
<code><b>name.xsd</b></code> the following C++ files are generated:
<code><b>name-pskel.hxx</b></code> (parser skeleton header file),
<code><b>name-pskel.ixx</b></code> (parser skeleton inline file,
generated only if the <code><b>--generate-inline</b></code>
option is specified), and
<code><b>name-pskel.cxx</b></code> (parser skeleton source file).
If the <code><b>--generate-noop-impl</b></code> or
<code><b>--generate-print-impl</b></code> option is specified,
the following additional sample implementation files are generated:
<code><b>name-pimpl.hxx</b></code> (parser implementation header
file) and
<code><b>name-pimpl.cxx</b></code> (parser implementation source
file). If the <code><b>--generate-test-driver</b></code> option
is specified, the additional <code><b>name-driver.cxx</b></code>
test driver file is generated.</dd>
<dt><code><b>help</b></code></dt>
<dd>Print usage information and exit. Use
<p><code><b>xsd help</b> <i>command</i></code></p>
for command-specific help.
</dd>
<dt><code><b>version</b></code></dt>
<dd>Print version and exit.</dd>
</dl>
<h1>OPTIONS</h1>
<p>Command-specific <code><i>options</i></code>, if any, should appear
after the corresponding <code><i>command</i></code>.</p>
<h2>COMMON OPTIONS</h2>
<dl class="options">
<dt><code><b>--std</b></code> <code><i>version</i></code></dt>
<dd>Specify the C++ standard that the generated code should conform to.
Valid values are <code><b>c++98</b></code> (default) and
<code><b>c++11</b></code>.
<p>The C++ standard affects various aspects of the generated code that are
discussed in more detail in various mapping-specific documentation.
Overall, when C++11 is selected, the generated code relies on the move
semantics and uses <code><b>std::unique_ptr</b></code> instead of
deprecated <code><b>std::auto_ptr</b></code>.</p>
<p>When the C++11 mode is selected, you normally don't need to perform any
extra steps other than enable C++11 in your C++ compiler, if required. The
XSD compiler will automatically add the necessary macro defines to the
generated header files that will switch the header-only XSD runtime
library (<code><b>libxsd</b></code>) to the C++11 mode. However, if you
include any of the XSD runtime headers directly in your application
(normally you just include the generated headers), then you will need to
define the <code><b>XSD_CXX11</b></code> macro for your entire
project.</p></dd>
<dt><code><b>--char-type</b></code> <code><i>type</i></code></dt>
<dd>Generate code using the provided character <code><i>type</i></code>
instead of the default <code><b>char</b></code>. Valid values are
<code><b>char</b></code> and <code><b>wchar_t</b></code>.</dd>
<dt><code><b>--char-encoding</b></code> <code><i>enc</i></code></dt>
<dd>Specify the character encoding that should be used in the generated
code. Valid values for the <code><b>char</b></code> character type are
<code><b>utf8</b></code> (default), <code><b>iso8859-1</b></code>,
<code><b>lcp</b></code> (Xerces-C++ local code page), and
<code><b>custom</b></code>. If you pass <code><b>custom</b></code> as the
value then you will need to include the transcoder implementation header
for your encoding at the beginning of the generated header files (see the
<code><b>--hxx-prologue</b></code> option).
<p>For the <code><b>wchar_t</b></code> character type the only valid value
is <code><b>auto</b></code> and the encoding is automatically selected
between UTF-16 and UTF-32/UCS-4, depending on the
<code><b>wchar_t</b></code> type size.</p></dd>
<dt><code><b>--output-dir</b></code> <code><i>dir</i></code></dt>
<dd>Write generated files to <code><i>dir</i></code> instead of the
current directory.</dd>
<dt><code><b>--generate-inline</b></code></dt>
<dd>Generate simple functions inline. This option triggers creation of the
inline file.</dd>
<dt><code><b>--generate-xml-schema</b></code></dt>
<dd>Generate a C++ header file as if the schema being compiled defines the
XML Schema namespace. For the C++/Tree mapping, the resulting file will
contain definitions for all XML Schema built-in types. For the C++/Parser
mapping, the resulting file will contain definitions for all the parser
skeletons and implementations corresponding to the XML Schema built-in
types.
<p>The schema file provided to the compiler need not exist and is only
used to derive the name of the resulting header file. Use the
<code><b>--extern-xml-schema</b></code> option to include this file in the
generated files for other schemas.</p></dd>
<dt><code><b>--extern-xml-schema</b></code> <code><i>file</i></code></dt>
<dd>Include a header file derived from <code><i>file</i></code> instead of
generating the XML Schema namespace mapping inline. The provided file need
not exist and is only used to derive the name of the included header file.
Use the <code><b>--generate-xml-schema</b></code> option to generate this
header file.</dd>
<dt><code><b>--namespace-map</b></code> <code><i>xns</i></code>=<code><i>cns</i></code></dt>
<dd>Map XML Schema namespace <code><i>xns</i></code> to C++ namespace
<code><i>cns</i></code>. Repeat this option to specify mapping for more
than one XML Schema namespace. For example, the following option:
<p class="code"><code><b>--namespace-map
http://example.com/foo/bar=foo::bar</b></code></p>
<p>Will map the <code><b>http://example.com/foo/bar</b></code> XML Schema
namespace to the <code><b>foo::bar</b></code> C++ namespace.</p></dd>
<dt><code><b>--namespace-regex</b></code> <code><i>regex</i></code></dt>
<dd>Add <code><i>regex</i></code> to the list of regular expressions used
to translate XML Schema namespace names to C++ namespace names.
<code><i>regex</i></code> is a Perl-like regular expression in the form
<code><b>/</b><i>pattern</i><b>/</b><i>replacement</i><b>/</b></code>. Any
character can be used as a delimiter instead of '<code><b>/</b></code>'.
Escaping of the delimiter character in <code><i>pattern</i></code> or
<code><i>replacement</i></code> is not supported.
<p>All the regular expressions are pushed into a stack with the last
specified expression considered first. The first match that succeeds is
used. Regular expressions are applied to a string in the form</p>
<p class="code"><code><i>filename</i> <i>namespace</i></code></p>
<p>For example, if you have file <code><b>hello.xsd</b></code> with
namespace <code><b>http://example.com/hello</b></code> and you run
<code><b>xsd</b></code> on this file, then the string in question will
be:</p>
<p class="code"><code><b>hello.xsd.
http://example.com/hello</b></code></p>
<p>For the built-in XML Schema namespace the string is:</p>
<p class="code"><code><b>XMLSchema.xsd
http://www.w3.org/2001/XMLSchema</b></code></p>
<p>The following three steps are performed for each regular expression
until the match is found:</p>
<p>1. The expression is applied and if the result is empty the next
expression is considered.</p>
<p>2. All '<code><b>/</b></code>' are replaced with
'<code><b>::</b></code>'.</p>
<p>3. The result is verified to be a valid C++ scope name (e.g.,
<code><b>foo::bar</b></code>). If this test succeeds, the result is used
as a C++ namespace name.</p>
<p>As an example, the following expression maps XML Schema namespaces in
the form <code><b>http://example.com/foo/bar</b></code> to C++ namespaces
in the form <code><b>foo::bar</b></code>:</p>
<p class="code"><code><b>%.* http://example.com/(.+)%$1%</b></code></p>
<p>See also the REGEX AND SHELL QUOTING section below.</p></dd>
<dt><code><b>--namespace-regex-trace</b></code></dt>
<dd>Trace the process of applying regular expressions specified with the
<code><b>--namespace-regex</b></code> option. Use this option to find out
why your regular expressions don't do what you expected them to do.</dd>
<dt><code><b>--reserved-name</b></code> <code><i>n</i></code>[=<code><i>r</i></code>]</dt>
<dd>Add name <code><i>n</i></code> to the list of names that should not be
used as identifiers. The name can optionally be followed by
<code><b>=</b></code> and the replacement name <code><i>r</i></code> that
should be used instead. All the C++ keywords are already in this
list.</dd>
<dt><code><b>--include-with-brackets</b></code></dt>
<dd>Use angle brackets (<>) instead of quotes ("") in generated
<code><b>#include</b></code> directives.</dd>
<dt><code><b>--include-prefix</b></code> <code><i>prefix</i></code></dt>
<dd>Add <code><i>prefix</i></code> to generated
<code><b>#include</b></code> directive paths.
<p>For example, if you had the following import element in your schema</p>
<p class="code"><code><b><import namespace="..."
schemaLocation="base.xsd"/></b></code></p>
<p>and compiled this fragment with <code><b>--include-prefix
schemas/</b></code>, then the include directive in the generated code
would be:</p>
<p class="code"><code><b>#include "schemas/base.hxx"</b></code></p></dd>
<dt><code><b>--include-regex</b></code> <code><i>regex</i></code></dt>
<dd>Add <code><i>regex</i></code> to the list of regular expressions used
to transform <code><b>#include</b></code> directive paths.
<code><i>regex</i></code> is a Perl-like regular expression in the form
<code><b>/</b><i>pattern</i><b>/</b><i>replacement</i><b>/</b></code>. Any
character can be used as a delimiter instead of '<code><b>/</b></code>'.
Escaping of the delimiter character in <code><i>pattern</i></code> or
<code><i>replacement</i></code> is not supported.
<p>All the regular expressions are pushed into a stack with the last
specified expression considered first. The first match that succeeds is
used.</p>
<p>As an example, the following expression transforms paths in the form
<code><b>schemas/foo/bar</b></code> to paths in the form
<code><b>generated/foo/bar</b></code>:</p>
<p class="code"><code><b>%schemas/(.+)%generated/$1%</b></code></p>
<p>See also the REGEX AND SHELL QUOTING section below.</p></dd>
<dt><code><b>--include-regex-trace</b></code></dt>
<dd>Trace the process of applying regular expressions specified with the
<code><b>--include-regex</b></code> option. Use this option to find out
why your regular expressions don't do what you expected them to do.</dd>
<dt><code><b>--guard-prefix</b></code> <code><i>prefix</i></code></dt>
<dd>Add <code><i>prefix</i></code> to generated header inclusion guards.
The prefix is transformed to upper case and characters that are illegal in
a preprocessor macro name are replaced with underscores. If this option is
not specified then the directory part of the input schema file is used as
a prefix.</dd>
<dt><code><b>--hxx-suffix</b></code> <code><i>suffix</i></code></dt>
<dd>Use the provided <code><i>suffix</i></code> instead of the default
<code><b>.hxx</b></code> to construct the name of the header file. Note
that this suffix is also used to construct names of header files
corresponding to included/imported schemas.</dd>
<dt><code><b>--ixx-suffix</b></code> <code><i>suffix</i></code></dt>
<dd>Use the provided <code><i>suffix</i></code> instead of the default
<code><b>.ixx</b></code> to construct the name of the inline file.</dd>
<dt><code><b>--cxx-suffix</b></code> <code><i>suffix</i></code></dt>
<dd>Use the provided <code><i>suffix</i></code> instead of the default
<code><b>.cxx</b></code> to construct the name of the source file.</dd>
<dt><code><b>--fwd-suffix</b></code> <code><i>suffix</i></code></dt>
<dd>Use the provided <code><i>suffix</i></code> instead of the default
<code><b>-fwd.hxx</b></code> to construct the name of the forward
declaration file.</dd>
<dt><code><b>--hxx-regex</b></code> <code><i>regex</i></code></dt>
<dd>Use the provided expression to construct the name of the header file.
<code><i>regex</i></code> is a Perl-like regular expression in the form
<code><b>/</b><i>pattern</i><b>/</b><i>replacement</i><b>/</b></code>.
Note that this expression is also used to construct names of header files
corresponding to included/imported schemas. See also the REGEX AND SHELL
QUOTING section below.</dd>
<dt><code><b>--ixx-regex</b></code> <code><i>regex</i></code></dt>
<dd>Use the provided expression to construct the name of the inline file.

control statements (<code><b>__declspec(dllexport/dllimport)</b></code>)
are necessary.</dd>
<dt><code><b>--export-xml-schema</b></code></dt>
<dd>Export/import types in the XML Schema namespace using the export
symbol provided with the <code><b>--export-symbol</b></code> option. The
<code><b>XSD_NO_EXPORT</b></code> macro can be used to omit this code
during C++ compilation, which may be useful if you would like to use the
same generated code across multiple platforms.</dd>
<dt><code><b>--export-maps</b></code></dt>
<dd>Export polymorphism support maps from a Win32 DLL into which this
generated code is placed. This is necessary when your type hierarchy is
split across several DLLs since otherwise each DLL will have its own set
of maps. In this situation the generated code for the DLL which contains
base types and/or substitution group heads should be compiled with this
option and the generated code for all other DLLs should be compiled with
<code><b>--import-maps</b></code>. This option is only valid together with
<code><b>--generate-polymorphic</b></code>. The
<code><b>XSD_NO_EXPORT</b></code> macro can be used to omit this code
during C++ compilation, which may be useful if you would like to use the
same generated code across multiple platforms.</dd>
<dt><code><b>--import-maps</b></code></dt>
<dd>Import polymorphism support maps to a Win32 DLL or executable into
which this generated code is linked. See the
<code><b>--export-maps</b></code> option documentation for details. This
options is only valid together with
<code><b>--generate-polymorphic</b></code>. The
<code><b>XSD_NO_EXPORT</b></code> macro can be used to omit this code
during C++ compilation, which may be useful if you would like to use the
same generated code across multiple platforms.</dd>
<dt><code><b>--generate-dep</b></code></dt>
<dd>Generate <code><b>make</b></code> dependency information. This option
triggers the creation of the <code><b>.d</b></code> file containing the
dependencies of the generated files on the main schema file as well as all
the schema files that it includes/imports, transitively. This dependency
file is then normally included into the main <code><b>makefile</b></code>
to implement automatic dependency tracking.
<p>Note also that automatic dependency generation is not supported in the
file-per-type mode (<code><b>--file-per-type</b></code>). In this case,
all the generated files are produced with a single compiler invocation and
depend on all the schemas. As a result, it is easier to establish such a
dependency manually, perhaps with the help of the
<code><b>--file-list*</b></code> options.</p></dd>
<dt><code><b>--generate-dep-only</b></code></dt>
<dd>Generate <code><b>make</b></code> dependency information only.</dd>
<dt><code><b>--dep-phony</b></code></dt>
<dd>Generate phony targets for included/imported schema files, causing
each to depend on nothing. Such dummy rules work around
<code><b>make</b></code> errors caused by the removal of schema files
without also updating the dependency file to match.</dd>
<dt><code><b>--dep-target</b></code> <code><i>target</i></code></dt>
<dd>Change the target of the dependency rule. By default it contains all
the generated C++ files as well as the dependency file itself, without any
directory prefixes. If you require multiple targets, then you can specify
them as a single, space-separated argument or you can repeat this option
multiple times.</dd>
<dt><code><b>--dep-suffix</b></code> <code><i>suffix</i></code></dt>
<dd>Use the provided <code><i>suffix</i></code> instead of the default
<code><b>.d</b></code> to construct the name of the dependency file.</dd>
<dt><code><b>--dep-regex</b></code> <code><i>regex</i></code></dt>
<dd>Use the provided expression to construct the name of the dependency
file. <code><i>regex</i></code> is a Perl-like regular expression in the
form
<code><b>/</b><i>pattern</i><b>/</b><i>replacement</i><b>/</b></code>. See
also the REGEX AND SHELL QUOTING section below.</dd>
<dt><code><b>--disable-warning</b></code> <code><i>warn</i></code></dt>
<dd>Disable printing warning with id <code><i>warn</i></code>. If
<code><b>all</b></code> is specified for the warning id then all warnings
are disabled.</dd>
<dt><code><b>--options-file</b></code> <code><i>file</i></code></dt>
<dd>Read additional options from <code><i>file</i></code>. Each option
should appearing on a separate line optionally followed by space and an
option value. Empty lines and lines starting with <code><b>#</b></code>
are ignored. Option values can be enclosed in double
(<code><b>"</b></code>) or single (<code><b>'</b></code>) quotes to
preserve leading and trailing whitespaces as well as to specify empty
values. If the value itself contains trailing or leading quotes, enclose
it with an extra pair of quotes, for example <code><b>'"x"'</b></code>.
Non-leading and non-trailing quotes are interpreted as being part of the
option value.
<p>The semantics of providing options in a file is equivalent to providing
the same set of options in the same order on the command line at the point
where the <code><b>--options-file</b></code> option is specified except
that the shell escaping and quoting is not required. You can repeat this
option to specify more than one options file.</p></dd>
<dt><code><b>--show-sloc</b></code></dt>
<dd>Show the number of generated physical source lines of code
(SLOC).</dd>
<dt><code><b>--sloc-limit</b></code> <code><i>num</i></code></dt>
<dd>Check that the number of generated physical source lines of code
(SLOC) does not exceed <code><i>num</i></code>.</dd>
<dt><code><b>--proprietary-license</b></code></dt>
<dd>Indicate that the generated code is licensed under a proprietary
license instead of the GPL.</dd>
<dt><code><b>--custom-literals</b></code> <code><i>file</i></code></dt>
<dd>Load custom XML string to C++ literal mappings from
<code><i>file</i></code>. This mechanism can be useful if you are using a
custom character encoding and some of the strings in your schemas, for
example element/attribute names or enumeration values, contain non-ASCII
characters. In this case you will need to provide a custom mapping to C++
literals for such strings. The format of this file is specified in the
<code><b>custom-literals.xsd</b></code> XML Schema file that can be found
in the documentation directory.</dd>
<dt><code><b>--preserve-anonymous</b></code></dt>
<dd>Preserve anonymous types. By default anonymous types are automatically
named with names derived from the enclosing elements/attributes. Because
mappings implemented by this compiler require all types to be named, this
option is only useful if you want to make sure your schemas don't have
anonymous types.</dd>
<dt><code><b>--show-anonymous</b></code></dt>
<dd>Show elements and attributes that are of anonymous types. This option
only makes sense together with the
<code><b>--preserve-anonymous</b></code> option.</dd>
<dt><code><b>--anonymous-regex</b></code> <code><i>regex</i></code></dt>
<dd>Add <code><i>regex</i></code> to the list of regular expressions used
to derive names for anonymous types from the enclosing
attributes/elements. <code><i>regex</i></code> is a Perl-like regular
expression in the form
<code><b>/</b><i>pattern</i><b>/</b><i>replacement</i><b>/</b></code>. Any
character can be used as a delimiter instead of '<code><b>/</b></code>'.
Escaping of the delimiter character in <code><i>pattern</i></code> or
<code><i>replacement</i></code> is not supported.
<p>All the regular expressions are pushed into a stack with the last
specified expression considered first. The first match that succeeds is
used. Regular expressions are applied to a string in the form</p>
<p class="code"><code><i>filename</i> <i>namespace</i>
<i>xpath</i></code></p>
<p>For instance:</p>
<p class="code"><code><b>hello.xsd http://example.com/hello
element</b></code></p>
<p class="code"><code><b>hello.xsd http://example.com/hello
type/element</b></code></p>
<p>As an example, the following expression makes all the derived names
start with capital letters. This could be useful when your naming
convention requires type names to start with capital letters:</p>
<p class="code"><code><b>%.* .* (.+/)*(.+)%\u$2%</b></code></p>
<p>See also the REGEX AND SHELL QUOTING section below.</p></dd>
<dt><code><b>--anonymous-regex-trace</b></code></dt>

why your regular expressions don't do what you expected them to do.</dd>
<dt><code><b>--location-map</b></code> <code><i>ol</i></code>=<code><i>nl</i></code></dt>
<dd>Map the original schema location <code><i>ol</i></code> that is
specified in the XML Schema include or import elements to new schema
location <code><i>nl</i></code>. Repeat this option to map more than one
schema location. For example, the following option maps the
<code><b>http://example.com/foo.xsd</b></code> URL to the
<code><b>foo.xsd</b></code> local file.
<p class="code"><code><b>--location-map
http://example.com/foo.xsd=foo.xsd</b></code></p></dd>

why your regular expressions don't do what you expected them to do.</dd>
<dt><code><b>--file-per-type</b></code></dt>
<dd>Generate a separate set of C++ files for each type defined in XML
Schema. Note that in this mode you only need to compile the root schema(s)
and the code will be generated for all included and imported schemas. This
compilation mode is primarily useful when some of your schemas cannot be
compiled separately or have cyclic dependencies which involve type
inheritance. Other options related to this mode are:
<code><b>--type-file-regex</b></code>,
<code><b>--schema-file-regex</b></code>,
<code><b>--fat-type-file</b></code>, and

Expressions are applied to the absolute filesystem path of a schema file
and the result, including the directory part, if any, is used to derive
the <code><b>#include</b></code> directive paths as well as the generated
C++ file paths. This option, along with
<code><b>--type-file-regex</b></code> are primarily useful to place the
generated files into subdirectories or to resolve file name conflicts.
<p>For example, the following expression maps schema files in the
<code><b>foo/1.0.0/</b></code> subdirectory to the files in the
<code><b>foo/</b></code> subdirectory. As a result, the
<code><b>#include</b></code> directive paths for such schemas will be in
the <code><b>foo/schema.hxx</b></code> form and the generated C++ files
will be placed into the <code><b>foo/</b></code> subdirectory:</p>
<p class="code"><code><b>%.*/foo/1.0.0/(.+)%foo/$1%</b></code></p>
<p>See also the REGEX AND SHELL QUOTING section below.</p></dd>
<dt><code><b>--schema-file-regex-trace</b></code></dt>

<code><b>--schema-file-regex</b></code> option. Use this option to find
out why your regular expressions don't do what you expected them to
do.</dd>
<dt><code><b>--fat-type-file</b></code></dt>
<dd>Generate code corresponding to global elements into type files instead
of schema files when the <code><b>--type-file-regex</b></code> option is
specified. This option is primarily useful when trying to minimize the
amount of object code that is linked to an executable by packaging
compiled generated code into a static (archive) library.</dd>
<dt><code><b>--file-list</b></code> <code><i>file</i></code></dt>
<dd>Write a list of generated C++ files to <code><i>file</i></code>. This

(<code><b>--file-per-type</b></code>) to create a list of generated C++
files, for example, as a makefile fragment.</dd>
<dt><code><b>--file-list-prologue</b></code> <code><i>text</i></code></dt>
<dd>Insert <code><i>text</i></code> at the beginning of the file list. As
a convenience, all occurrences of the <code><b>\n</b></code> character
sequence in <code><i>text</i></code> are replaced with new lines. This
option can, for example, be used to assign the generated file list to a
makefile variable.</dd>
<dt><code><b>--file-list-epilogue</b></code> <code><i>text</i></code></dt>
<dd>Insert <code><i>text</i></code> at the end of the file list. As a

</dl>
<h2>CXX-TREE COMMAND OPTIONS</h2>
<dl class="options">
<dt><code><b>--generate-polymorphic</b></code></dt>
<dd>Generate polymorphism-aware code. Specify this option if you use
substitution groups or <code><b>xsi:type</b></code>. Use the
<code><b>--polymorphic-type</b></code> or
<code><b>--polymorphic-type-all</b></code> option to specify which type
hierarchies are polymorphic.</dd>
<dt><code><b>--polymorphic-type</b></code> <code><i>type</i></code></dt>
<dd>Indicate that <code><i>type</i></code> is a root of a polymorphic type
hierarchy. The compiler can often automatically determine which types are
polymorphic based on the substitution group declarations. However, you may
need to use this option if you are not using substitution groups or if
substitution groups are defined in another schema. You need to specify
this option when compiling every schema file that references
<code><i>type</i></code>. The <code><i>type</i></code> argument is an XML
Schema type name that can be optionally qualified with a namespace in the
<code><i>namespace</i><b>#</b><i>name</i></code> form.</dd>
<dt><code><b>--polymorphic-type-all</b></code></dt>
<dd>Indicate that all types should be treated as polymorphic.</dd>
<dt><code><b>--polymorphic-plate</b></code> <code><i>num</i></code></dt>
<dd>Specify the polymorphic map plate the generated code should register
on. This functionality is primarily useful to segregate multiple schemas
that define the same polymorphic types.</dd>
<dt><code><b>--ordered-type</b></code> <code><i>type</i></code></dt>
<dd>Indicate that element order in <code><i>type</i></code> is
significant. An example would be a complex type with unbounded choice as a
content model where the element order in XML has application-specific
semantics. For ordered types the compiler generates a special container
data member and a corresponding set of accessors and modifiers that are
used to capture the order of elements and, for mixed content, of text.
<p>The <code><i>type</i></code> argument is an XML Schema type name that
can be optionally qualified with a namespace in the
<code><i>namespace</i><b>#</b><i>name</i></code> form. Note also that you
will need to specify this option when compiling every schema file that has
other ordered types derived from this type.</p></dd>
<dt><code><b>--ordered-type-derived</b></code></dt>
<dd>Automatically treat types derived from ordered bases as also ordered.
This is primarily useful if you would like to be able to iterate over the
complete content using the content order container.</dd>
<dt><code><b>--ordered-type-mixed</b></code></dt>
<dd>Automatically treat complex types with mixed content as ordered.</dd>
<dt><code><b>--ordered-type-all</b></code></dt>
<dd>Indicate that element order in all types is significant.</dd>
<dt><code><b>--order-container</b></code> <code><i>type</i></code></dt>
<dd>Specify a custom class template that should be used as a container for
the content order in ordered types instead of the default
<code><b>std::vector</b></code>. See <code><b>--ordered-type</b></code>
for more information on ordered type. This option is primarily useful if
you need to perform more complex lookups in the content order container,
for example by element id. In this case, a container like Boost
multi-index may be more convenient. Note that if using a custom container,
you will also most likely need to include the relevant headers using the
<code><b>--hxx-prologue*</b></code> options.</dd>
<dt><code><b>--generate-serialization</b></code></dt>
<dd>Generate serialization functions. Serialization functions convert the
object model back to XML.</dd>
<dt><code><b>--generate-ostream</b></code></dt>
<dd>Generate ostream insertion operators
(<code><b>operator<<</b></code>) for generated types. This allows
one to easily print a fragment or the whole object model for debugging or
logging.</dd>
<dt><code><b>--generate-doxygen</b></code></dt>
<dd>Generate documentation comments suitable for extraction by the Doxygen
documentation system. Documentation from annotations is added to the
comments if present in the schema.</dd>
<dt><code><b>--generate-comparison</b></code></dt>
<dd>Generate comparison operators (<code><b>operator==</b></code> and
<code><b>operator!=</b></code>) for complex types. Comparison is performed
member-wise.</dd>
<dt><code><b>--generate-default-ctor</b></code></dt>
<dd>Generate default constructors even for types that have required
members. Required members of an instance constructed using such a
constructor are not initialized and accessing them results in undefined
behavior.</dd>
<dt><code><b>--generate-from-base-ctor</b></code></dt>
<dd>Generate constructors that expect an instance of a base type followed
by all required members.</dd>
<dt><code><b>--suppress-assignment</b></code></dt>
<dd>Suppress the generation of copy assignment operators for complex
types. If this option is specified, the copy assignment operators for such
types are declared private and left unimplemented.</dd>
<dt><code><b>--generate-detach</b></code></dt>
<dd>Generate detach functions for required elements and attributes. Detach
functions for optional and sequence cardinalities are provided by the
respective containers. These functions, for example, allow you to move
sub-trees in the object model either within the same tree or between
different trees.</dd>
<dt><code><b>--generate-wildcard</b></code></dt>
<dd>Generate accessors and modifiers as well as parsing and serialization
code for XML Schema wildcards (<code><b>any</b></code> and
<code><b>anyAttribute</b></code>). XML content matched by wildcards is
presented as DOM fragments. Note that you need to initialize the
Xerces-C++ runtime if you are using this option.</dd>
<dt><code><b>--generate-any-type</b></code></dt>
<dd>Extract and store content of the XML Schema
<code><b>anyType</b></code> type as a DOM fragment. Note that you need to
initialize the Xerces-C++ runtime if you are using this option.</dd>
<dt><code><b>--generate-insertion</b></code> <code><i>os</i></code></dt>
<dd>Generate data representation stream insertion operators for the
<code><i>os</i></code> output stream type. Repeat this option to specify
more than one stream type. The ACE CDR stream
(<code><b>ACE_OutputCDR</b></code>) and RPC XDR are recognized by the
compiler and the necessary <code><b>#include</b></code> directives are
automatically generated. For custom stream types use the
<code><b>--hxx-prologue*</b></code> options to provide the necessary
declarations.</dd>
<dt><code><b>--generate-extraction</b></code> <code><i>is</i></code></dt>
<dd>Generate data representation stream extraction constructors for the
<code><i>is</i></code> input stream type. Repeat this option to specify
more than one stream type. The ACE CDR stream
(<code><b>ACE_InputCDR</b></code>) and RPC XDR are recognized by the
compiler and the necessary <code><b>#include</b></code> directives are
automatically generated. For custom stream types use the
<code><b>--hxx-prologue*</b></code> options to provide the necessary
declarations.</dd>
<dt><code><b>--generate-forward</b></code></dt>
<dd>Generate a separate header file with forward declarations for the
types being generated.</dd>
<dt><code><b>--suppress-parsing</b></code></dt>
<dd>Suppress the generation of the parsing functions and constructors. Use
this option to reduce the generated code size when parsing from XML is not
needed.</dd>
<dt><code><b>--generate-element-type</b></code></dt>
<dd>Generate types instead of parsing and serialization functions for root
elements. This is primarily useful to distinguish object models with the
same root type but with different root elements.</dd>
<dt><code><b>--generate-element-map</b></code></dt>
<dd>Generate a root element map that allows uniform parsing and
serialization of multiple root elements. This option is only valid
together with <code><b>--generate-element-type</b></code>.</dd>
<dt><code><b>--generate-intellisense</b></code></dt>
<dd>Generate workarounds for IntelliSense bugs in Visual Studio 2005
(8.0). When this option is used, the resulting code is slightly more
verbose. IntelliSense in Visual Studio 2008 (9.0) and later does not
require these workarounds. Support for IntelliSense in Visual Studio 2003
(7.1) is improved with this option but is still incomplete.</dd>
<dt><code><b>--omit-default-attributes</b></code></dt>
<dd>Omit attributes with default and fixed values from serialized XML
documents.</dd>
<dt><code><b>--type-naming</b></code> <code><i>style</i></code></dt>
<dd>Specify the type naming convention that should be used in the
generated code. Valid styles are <code><b>knr</b></code> (default),
<code><b>ucc</b></code>, and <code><b>java</b></code>. See the NAMING
CONVENTION section below for more information.</dd>
<dt><code><b>--function-naming</b></code> <code><i>style</i></code></dt>

<dd>Treat only <code><i>element</i></code> as a document root. Repeat this
option to specify more than one root element.</dd>
<dt><code><b>--custom-type</b></code> <code><i>map</i></code></dt>
<dd>Use a custom C++ type instead of the generated class. The

<code><i>name</i>[<b>=</b><i>type</i>[<b>/</b><i>base</i>]]</code>, where
<i>name</i> is a type name as defined in XML Schema and <i>type</i> is a
C++ type name that should be used instead. If <i>type</i> is not present
or empty then the custom type is assumed to have the same name and be
defined in the same namespace as the generated class would have. If
<i>base</i> is specified then the generated class is still generated but
with that name.</dd>
<dt><code><b>--custom-type-regex</b></code> <code><i>regex</i></code></dt>
<dd>Use custom C++ types instead of the generated classes. The
<code><i>regex</i></code> argument is in the form
<code><b>/</b><i>name-pat</i><b>/</b>[<i>type-sub</i><b>/</b>[<i>base-sub</i><b>/</b>]]</code>,
where <i>name-pat</i> is a regex pattern that will be matched against type
names as defined in XML Schema and <i>type-sub</i> is a C++ type name
substitution that should be used instead. If <i>type-sub</i> is not
present or its substitution results in an empty string then the custom
type is assumed to have the same name and be defined in the same namespace
as the generated class would have. If <i>base-sub</i> is present and its
substitution results in a non-empty string then the generated class is
still generated but with the result of this substitution as its name. The
pattern and substitutions are in the Perl regular expression format. See
also the REGEX AND SHELL QUOTING section below.</dd>
<dt><code><b>--parts</b></code> <code><i>num</i></code></dt>
<dd>Split generated source code into <code><i>num</i></code> parts. This

<h1>NAMING CONVENTION</h1>
<p>The compiler can be instructed to use a particular naming
convention in the generated code. A number of widely-used
conventions can be selected using the <code><b>--type-naming</b></code>
and <code><b>--function-naming</b></code> options. A custom
naming convention can be achieved using the
<code><b>--type-regex</b></code>,
<code><b>--accessor-regex</b></code>,
<code><b>--one-accessor-regex</b></code>,
<code><b>--opt-accessor-regex</b></code>,
<code><b>--seq-accessor-regex</b></code>,
<code><b>--modifier-regex</b></code>,
<code><b>--one-modifier-regex</b></code>,
<code><b>--opt-modifier-regex</b></code>,
<code><b>--seq-modifier-regex</b></code>,
<code><b>--parser-regex</b></code>,
<code><b>--serializer-regex</b></code>,
<code><b>--const-regex</b></code>,
<code><b>--enumerator-regex</b></code>, and
<code><b>--element-type-regex</b></code> options.
</p>
<p>The <code><b>--type-naming</b></code> option specifies the
convention that should be used for naming C++ types. Possible
values for this option are <code><b>knr</b></code> (default),
<code><b>ucc</b></code>, and <code><b>java</b></code>. The
<code><b>knr</b></code> value (stands for K&R) signifies
the standard, lower-case naming convention with the underscore
used as a word delimiter, for example: <code>foo</code>,
<code>foo_bar</code>. The <code><b>ucc</b></code> (stands
for upper-camel-case) and
<code><b>java</b></code> values a synonyms for the same
naming convention where the first letter of each word in the
name is capitalized, for example: <code>Foo</code>,
<code>FooBar</code>.</p>
<p>Similarly, the <code><b>--function-naming</b></code> option
specifies the convention that should be used for naming C++
functions. Possible values for this option are <code><b>knr</b></code>
(default), <code><b>lcc</b></code>, <code><b>ucc</b></code>, and
<code><b>java</b></code>. The <code><b>knr</b></code> value (stands
for K&R) signifies the standard, lower-case naming convention
with the underscore used as a word delimiter, for example:
<code>foo()</code>, <code>foo_bar()</code>. The <code><b>lcc</b></code>
value (stands for lower-camel-case) signifies a naming convention
where the first letter of each word except the first is capitalized,
for example: <code>foo()</code>, <code>fooBar()</code>. The
<code><b>ucc</b></code> value (stands for upper-camel-case) signifies
a naming convention where the first letter of each word is capitalized,
for example: <code>Foo()</code>, <code>FooBar()</code>.
The <code><b>java</b></code> naming convention is similar to
the lower-camel-case one except that accessor functions are prefixed
with <code>get</code>, modifier functions are prefixed
with <code>set</code>, parsing functions are prefixed
with <code>parse</code>, and serialization functions are
prefixed with <code>serialize</code>, for example:
<code>getFoo()</code>, <code>setFooBar()</code>,
<code>parseRoot()</code>, <code>serializeRoot()</code>.</p>
<p>Note that the naming conventions specified with the
<code><b>--type-naming</b></code> and
<code><b>--function-naming</b></code> options perform only limited
transformations on the names that come from the schema in the
form of type, attribute, and element names. In other words, to
get consistent results, your schemas should follow a similar
naming convention as the one you would like to have in the
generated code. Alternatively, you can use the
<code><b>--*-regex</b></code> options (discussed below)
to perform further transformations on the names that come from
the schema.</p>
<p>The
<code><b>--type-regex</b></code>,
<code><b>--accessor-regex</b></code>,
<code><b>--one-accessor-regex</b></code>,
<code><b>--opt-accessor-regex</b></code>,
<code><b>--seq-accessor-regex</b></code>,
<code><b>--modifier-regex</b></code>,
<code><b>--one-modifier-regex</b></code>,
<code><b>--opt-modifier-regex</b></code>,
<code><b>--seq-modifier-regex</b></code>,
<code><b>--parser-regex</b></code>,
<code><b>--serializer-regex</b></code>,
<code><b>--const-regex</b></code>,
<code><b>--enumerator-regex</b></code>, and
<code><b>--element-type-regex</b></code> options allow you to
specify extra regular expressions for each name category in
addition to the predefined set that is added depending on
the <code><b>--type-naming</b></code> and
<code><b>--function-naming</b></code> options. Expressions
that are provided with the <code><b>--*-regex</b></code>
options are evaluated prior to any predefined expressions.
This allows you to selectively override some or all of the
predefined transformations. When debugging your own expressions,
it is often useful to see which expressions match which names.
The <code><b>--name-regex-trace</b></code> option allows you
to trace the process of applying regular expressions to
names.</p>
<p>The value for the <code><b>--*-regex</b></code> options should be
a perl-like regular expression in the form
<code><b>/</b><i>pattern</i><b>/</b><i>replacement</i><b>/</b></code>.
Any character can be used as a delimiter instead of <code><b>/</b></code>.
Escaping of the delimiter character in <code><i>pattern</i></code> or
<code><i>replacement</i></code> is not supported.
All the regular expressions for each category are pushed into a
category-specific stack with the last specified expression
considered first. The first match that succeeds is used. For the
<code><b>--one-accessor-regex</b></code> (accessors with cardinality one),
<code><b>--opt-accessor-regex</b></code> (accessors with cardinality optional), and
<code><b>--seq-accessor-regex</b></code> (accessors with cardinality sequence)
categories the <code><b>--accessor-regex</b></code> expressions are
used as a fallback. For the
<code><b>--one-modifier-regex</b></code>,
<code><b>--opt-modifier-regex</b></code>, and
<code><b>--seq-modifier-regex</b></code>
categories the <code><b>--modifier-regex</b></code> expressions are
used as a fallback. For the <code><b>--element-type-regex</b></code>
category the <code><b>--type-regex</b></code> expressions are
used as a fallback.</p>
<p>The type name expressions (<code><b>--type-regex</b></code>)
are evaluated on the name string that has the following
format:</p>
<p><code>[<i>namespace</i> ]<i>name</i>[,<i>name</i>][,<i>name</i>][,<i>name</i>]</code></p>
<p>The element type name expressions
(<code><b>--element-type-regex</b></code>), effective only when
the <code><b>--generate-element-type</b></code> option is specified,
are evaluated on the name string that has the following
format:</p>
<p><code><i>namespace</i> <i>name</i></code></p>
<p>In the type name format the <code><i>namespace</i></code> part
followed by a space is only present for global type names. For
global types and elements defined in schemas without a target
namespace, the <code><i>namespace</i></code> part is empty but
the space is still present. In the type name format after the
initial <code><i>name</i></code> component, up to three additional
<code><i>name</i></code> components can be present, separated
by commas. For example:</p>
<p><code><b>http://example.com/hello type</b></code></p>
<p><code><b>foo</b></code></p>
<p><code><b>foo,iterator</b></code></p>
<p><code><b>foo,const,iterator</b></code></p>
<p>The following set of predefined regular expressions is used to
transform type names when the upper-camel-case naming convention
is selected:</p>
<p><code><b>/(?:[^ ]* )?([^,]+)/\u$1/</b></code></p>
<p><code><b>/(?:[^ ]* )?([^,]+),([^,]+)/\u$1\u$2/</b></code></p>
<p><code><b>/(?:[^ ]* )?([^,]+),([^,]+),([^,]+)/\u$1\u$2\u$3/</b></code></p>
<p><code><b>/(?:[^ ]* )?([^,]+),([^,]+),([^,]+),([^,]+)/\u$1\u$2\u$3\u$4/</b></code></p>
<p>The accessor and modifier expressions
(<code><b>--*accessor-regex</b></code> and
<code><b>--*modifier-regex</b></code>) are evaluated on the name string
that has the following format:</p>
<p><code><i>name</i>[,<i>name</i>][,<i>name</i>]</code></p>
<p>After the initial <code><i>name</i></code> component, up to two
additional <code><i>name</i></code> components can be present,
separated by commas. For example:</p>
<p><code><b>foo</b></code></p>
<p><code><b>dom,document</b></code></p>
<p><code><b>foo,default,value</b></code></p>
<p>The following set of predefined regular expressions is used to
transform accessor names when the <code><b>java</b></code> naming
convention is selected:</p>
<p><code><b>/([^,]+)/get\u$1/</b></code></p>
<p><code><b>/([^,]+),([^,]+)/get\u$1\u$2/</b></code></p>
<p><code><b>/([^,]+),([^,]+),([^,]+)/get\u$1\u$2\u$3/</b></code></p>
<p>For the parser, serializer, and enumerator categories, the
corresponding regular expressions are evaluated on local names of
elements and on enumeration values, respectively. For example, the
following predefined regular expression is used to transform parsing
function names when the <code><b>java</b></code> naming convention
is selected:</p>
<p><code><b>/(.+)/parse\u$1/</b></code></p>
<p>The const category is used to create C++ constant names for the
element/wildcard/text content ids in ordered types.</p>
<p>See also the REGEX AND SHELL QUOTING section below.</p>
<h1>TYPE MAP</h1>
<p>Type map files are used in C++/Parser to define a mapping between
XML Schema and C++ types. The compiler uses this information
to determine the return types of <code><b>post_*</b></code>
functions in parser skeletons corresponding to XML Schema
types as well as argument types for callbacks corresponding
to elements and attributes of these types.</p>
<p>The compiler has a set of predefined mapping rules that map
built-in XML Schema types to suitable C++ types (discussed
below) and all other types to <code><b>void</b></code>.
By providing your own type maps you can override these predefined
rules. The format of the type map file is presented below:
</p>
<pre>
namespace <schema-namespace> [<cxx-namespace>]
{
(include <file-name>;)*
([type] <schema-type> <cxx-ret-type> [<cxx-arg-type>];)*
}
</pre>
<p>Both <code><i><schema-namespace></i></code> and
<code><i><schema-type></i></code> are regex patterns while
<code><i><cxx-namespace></i></code>,
<code><i><cxx-ret-type></i></code>, and
<code><i><cxx-arg-type></i></code> are regex pattern
substitutions. All names can be optionally enclosed in
<code><b>" "</b></code>, for example, to include white-spaces.</p>
<p><code><i><schema-namespace></i></code> determines XML
Schema namespace. Optional <code><i><cxx-namespace></i></code>
is prefixed to every C++ type name in this namespace declaration.
<code><i><cxx-ret-type></i></code> is a C++ type name that is
used as a return type for the <code><b>post_*</b></code> functions.
Optional <code><i><cxx-arg-type></i></code> is an argument
type for callback functions corresponding to elements and attributes
of this type. If
<code><i><cxx-arg-type></i></code> is not specified, it defaults
to <code><i><cxx-ret-type></i></code> if <code><i><cxx-ret-type></i></code>
ends with <code><b>*</b></code> or <code><b>&</b></code> (that is,
it is a pointer or a reference) and
<code><b>const</b> <i><cxx-ret-type></i><b>&</b></code>
otherwise.
<code><i><file-name></i></code> is a file name either in the
<code><b>" "</b></code> or <code><b>< ></b></code> format
and is added with the <code><b>#include</b></code> directive to
the generated code.</p>
<p>The <code><b>#</b></code> character starts a comment that ends
with a new line or end of file. To specify a name that contains
<code><b>#</b></code> enclose it in <code><b>" "</b></code>.
For example:</p>
<pre>
namespace http://www.example.com/xmlns/my my
{
include "my.hxx";
# Pass apples by value.
#
apple apple;
# Pass oranges as pointers.
#
orange orange_t*;
}
</pre>
<p>In the example above, for the
<code><b>http://www.example.com/xmlns/my#orange</b></code>
XML Schema type, the <code><b>my::orange_t*</b></code> C++ type will
be used as both return and argument types.</p>
<p>Several namespace declarations can be specified in a single
file. The namespace declaration can also be completely
omitted to map types in a schema without a namespace. For
instance:</p>
<pre>
include "my.hxx";
apple apple;
namespace http://www.example.com/xmlns/my
{
orange "const orange_t*";
}
</pre>
<p>The compiler has a number of predefined mapping rules that can be
presented as the following map files. The string-based XML Schema
built-in types are mapped to either <code><b>std::string</b></code>
or <code><b>std::wstring</b></code> depending on the character type
selected with the <code><b>--char-type</b></code> option
(<code><b>char</b></code> by default).</p>
<pre>
namespace http://www.w3.org/2001/XMLSchema
{
boolean bool bool;
byte "signed char" "signed char";
unsignedByte "unsigned char" "unsigned char";
short short short;
unsignedShort "unsigned short" "unsigned short";
int int int;
unsignedInt "unsigned int" "unsigned int";
long "long long" "long long";
unsignedLong "unsigned long long" "unsigned long long";
integer "long long" "long long";
negativeInteger "long long" "long long";
nonPositiveInteger "long long" "long long";
positiveInteger "unsigned long long" "unsigned long long";
nonNegativeInteger "unsigned long long" "unsigned long long";
float float float;
double double double;
decimal double double;
string std::string;
normalizedString std::string;
token std::string;
Name std::string;
NMTOKEN std::string;
NCName std::string;
ID std::string;
IDREF std::string;
language std::string;
anyURI std::string;
NMTOKENS xml_schema::string_sequence;
IDREFS xml_schema::string_sequence;
QName xml_schema::qname;
base64Binary std::auto_ptr<xml_schema::buffer>
std::auto_ptr<xml_schema::buffer>;
hexBinary std::auto_ptr<xml_schema::buffer>
std::auto_ptr<xml_schema::buffer>;
date xml_schema::date;
dateTime xml_schema::date_time;
duration xml_schema::duration;
gDay xml_schema::gday;
gMonth xml_schema::gmonth;
gMonthDay xml_schema::gmonth_day;
gYear xml_schema::gyear;
gYearMonth xml_schema::gyear_month;
time xml_schema::time;
}
</pre>
<p>The last predefined rule maps anything that wasn't mapped by
previous rules to <code><b>void</b></code>:</p>
<pre>
namespace .*
{
.* void void;
}
</pre>
<p>When you provide your own type maps with the
<code><b>--type-map</b></code> option, they are evaluated first.
This allows you to selectively override predefined rules.</p>
<h1>REGEX AND SHELL QUOTING</h1>
<p>When entering a regular expression argument in the shell
command line it is often necessary to use quoting (enclosing
the argument in <code><b>" "</b></code> or
<code><b>' '</b></code>) in order to prevent the shell
from interpreting certain characters, for example, spaces as
argument separators and <code><b>$</b></code> as variable
expansions.</p>
<p>Unfortunately it is hard to achieve this in a manner that is
portable across POSIX shells, such as those found on
GNU/Linux and UNIX, and Windows shell. For example, if you
use <code><b>" "</b></code> for quoting you will get a
wrong result with POSIX shells if your expression contains
<code><b>$</b></code>. The standard way of dealing with this
on POSIX systems is to use <code><b>' '</b></code> instead.
Unfortunately, Windows shell does not remove <code><b>' '</b></code>
from arguments when they are passed to applications. As a result you
may have to use <code><b>' '</b></code> for POSIX and
<code><b>" "</b></code> for Windows (<code><b>$</b></code> is
not treated as a special character on Windows).</p>
<p>Alternatively, you can save regular expression options into
a file, one option per line, and use this file with the
<code><b>--options-file</b></code> option. With this approach
you don't need to worry about shell quoting.</p>
<h1>DIAGNOSTICS</h1>
<p>If the input file is not a valid W3C XML Schema definition,
<code><b>xsd</b></code> will issue diagnostic messages to STDERR
and exit with non-zero exit code.</p>
