.SH DESCRIPTION
.\"--------------------------------------------------------------------
.B xsd
generates vocabulary-specific, statically-typed C++ mapping from W3C XML
Schema definitions. Particular mapping to produce is selected by a
.IR command .
Each mapping has a number of mapping-specific
.I options
that should appear, if any, after the
.IR command .
Input files should be W3C XML Schema definitions. The exact set of the
generated files depends on the selected mapping and options.

.\"--------------------------------------------------------------------
.SH COMMANDS
.\"--------------------------------------------------------------------
.IP \fBcxx-tree\fR
Generate the C++/Tree mapping. For each input file in the form
.B name.xsd
the following C++ files are generated:
.B name.hxx
(header file),
.B name.ixx
(inline file, generated only if the
.B --generate-inline
option is specified),
.B name.cxx
(source file), and
.B name-fwd.hxx
(forward declaration file, generated only if the
.B --generate-forward
option is specified).

.IP \fBcxx-parser\fR
Generate the C++/Parser mapping. For each input file in the form
.B name.xsd
the following C++ files are generated:
.B name-pskel.hxx
(parser skeleton header file),
.B name-pskel.ixx
(parser skeleton inline file, generated only if the
.B --generate-inline
option is specified), and
.B name-pskel.cxx
(parser skeleton source file). If the
.B --generate-noop-impl
or
.B --generate-print-impl
option is specified, the following additional sample implementation files
are generated:
.B name-pimpl.hxx
(parser implementation header file) and
.B name-pimpl.cxx
(parser implementation source file). If the
.B --generate-test-driver
option is specified, the additional
.B name-driver.cxx
test driver file is generated.

.SS common options
.
.IP "\fB\--char-type \fItype\fR"
Generate code using the provided character
.I type
instead of the default
.BR char .
Valid values are
.B char
and
.BR wchar_t .
.
.IP "\fB\--char-encoding \fIenc\fR"
Specify the character encoding that should be used in the generated code.
Valid values for the
.B char
character type are
.B utf8
(default),
.BR iso8859-1 , lcp
(Xerces-C++ local code page),
and
.BR custom .
If you pass
.B custom
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
.B --hxx-prologue
option).

For the
.B wchar_t
character type the only valid value is
.B auto
and the encoding is automatically selected between UTF-16 and UTF-32/UCS-4,
depending on the
.B wchar_t
type size.
.
.IP "\fB\--output-dir \fIdir\fR"
Write generated files to
.I dir
instead of the current directory.

.IP "\fB\--namespace-map \fIxns\fB=\fIcns"
Map XML Schema namespace
.I xns
to C++ namespace
.IR cns .
Repeat this option to specify mapping for more than one XML Schema namespace.
For example, the following option:

.B --namespace-map http://example.com/foo/bar=foo::bar

will map the
.B http://example.com/foo/bar
XML Schema namespace to the
.B foo::bar
C++ namespace.
.
.IP "\fB\--namespace-regex \fIregex\fR"
Add
.I regex
to the list of regular expressions used to translate XML Schema namespace
names to C++ namespace names.
.I regex
is a perl-like regular expression in the form
.BI / pattern / replacement /\fR.
Any character can be used as a delimiter instead of
.BR / .
Escaping of the delimiter character in
.I pattern
or
.I replacement
is not supported.

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

.I filename namespace

For example, if you have file
.B hello.xsd
with namespace
.B http://example.com/hello
and you run
.B xsd
on this file, then the string in question will be:

.B hello.xsd. http://example.com/hello

For the built-in XML Schema namespace the string is:

.B XMLSchema.xsd http://www.w3.org/2001/XMLSchema

The following three steps are performed for each regular expression until
the match is found:
.RS
.RS 3
.TP 3
1.
The expression is applied and if the result is empty the next expression
is considered.
.TP 3
2.
All
.B /
are replaced with
.BR :: .
.TP 3
3.
The result is verified to be a valid C++ scope name (e.g.,
.BR foo::bar ).
If this test succeeds, the result is used as a C++ namespace name.
.RE
.PP
As an example, the following expression maps XML Schema namespaces in the
form
.B http://example.com/foo/bar
to C++ namespaces in the form
.BR foo::bar :
.PP
.B "%.* http://example.com/(.+)%$1%"

.RE

.IP "\fB\--namespace-regex-trace\fR"
Trace the process of applying regular expressions specified with
the
.B --namespace-regex
option. Use this option to find out why your regular expressions
don't do what you expected them to do.

\"
\" Reserved names.
\"

.IP "\fB\--reserved-name \fIname\fR[\fB=\fIrep\fR]"
Add
.I name
to the list of names that should not be used as identifiers. The name
can optionally be followed by
.B =
and the replacement name that should be used instead. All the C++ keywords
are already in this list.

\"
\" Include
\"

.IP "\fB\--include-with-brackets\fR"
Use angle brackets (<>) instead of quotes ("") in generated
.B #include
directives.

.IP "\fB\--include-prefix \fIprefix\fR"
Add
.I prefix
to generated
.B #include
directive paths.

For example, if you had the following import element in your schema

.B <import namespace="..." schemaLocation="base.xsd"/>

and compiled this fragment with
.B --include-prefix schemas/\fR,
then the include directive in the generated code would be:

.B #include "schemas/base.hxx"

.IP "\fB\--include-regex \fIregex\fR"
Add
.I regex
to the list of regular expressions used to transform
.B #include
directive paths.
.I regex
is a perl-like regular expression in the form
.BI / pattern / replacement /\fR.
Any character can be used as a delimiter instead of
.BR / .
Escaping of the delimiter character in
.I pattern
or
.I replacement
is not supported.

All the regular expressions are pushed into a stack with the last specified
expression considered first. The first match that succeeds is used.

As an example, the following expression transforms paths in the form
.B schemas/foo/bar
to paths in the form
.BR generated/foo/bar :

.B "%schemas/(.+)%generated/$1%"

See also the REGEX AND SHELL QUOTING section below.

.IP "\fB\--include-regex-trace\fR"
Trace the process of applying regular expressions specified with
the
.B --include-regex
option. Use this option to find out why your regular expressions
don't do what you expected them to do.

.IP "\fB\--guard-prefix \fIprefix\fR"
Add
.I prefix
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.

.\"
.\" Suffixes.
.\"

.IP "\fB\--hxx-suffix \fIsuffix\fR"

.IR file .
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

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
.BR --import-maps .
This option is only valid together with
.BR --generate-polymorphic.

.IP "\fB\--sloc-limit \fInum\fR"
Check that the number of generated physical source lines of code (SLOC)
does not exceed
.I num.

.IP "\fB\--options-file \fIfile\fR"
Read additional options from
.IR file .
Each option should appear on a separate line optionally followed by
space and an argument. Empty lines and lines starting with
.B #
are ignored. The semantics of providing options in a file is equivalent
to providing the same set of options in the same order in the command
line at the point where the
.B --options-file
option is specified except that shell escaping and quoting is not
required. Repeat this option to specify more than one options files.

.IP "\fB\--proprietary-license\fR"
Indicate that the generated code is licensed under a proprietary license
instead of the GPL.

.IP "\fB\--preserve-anonymous\fR"
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.

.IP "\fB\--show-anonymous\fR"
Show elements and attributes that are of anonymous types. This option
only makes sense together with the
.B --preserve-anonymous
option.

.IP "\fB\--anonymous-regex \fIregex\fR"
Add
.I regex
to the list of regular expressions used to derive names for anonymous
types from the enclosing attributes/elements.
.I regex
is a perl-like regular expression in the form
.BI / pattern / replacement /\fR.
Any character can be used as a delimiter instead of
.BR / .
Escaping of the delimiter character in
.I pattern
or
.I replacement
is not supported.

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

.I filename namespace xpath

For instance:

.B hello.xsd http://example.com/hello element

.B hello.xsd http://example.com/hello type/element

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:

.B %.* .* (.+/)*(.+)%\\\\u$2%

See also the REGEX AND SHELL QUOTING section below.

.IP "\fB\--anonymous-regex-trace\fR"
Trace the process of applying regular expressions specified with
the
.B --anonymous-regex

don't do what you expected them to do.

.IP "\fB\--location-map \fIol\fB=\fInl"
Map the original schema location
.I ol
that is specified in the XML Schema include or import elements to new
schema location
.IR nl .
Repeat this option to map more than one schema location. For example,
the following option maps the
.B http://example.com/foo.xsd
URL to the
.B foo.xsd
local file.

.B --location-map http://example.com/foo.xsd=foo.xsd

.IP "\fB\--location-regex \fIregex\fR"
Add
.I regex
to the list of regular expressions used to map schema locations that are
specified in the XML Schema include or import elements.
.I regex
is a perl-like regular expression in the form
.BI / pattern / replacement /\fR.
Any character can be used as a delimiter instead of
.BR / .
Escaping of the delimiter character in
.I pattern
or
.I replacement
is not supported. All the regular expressions are pushed into a stack with the
last specified expression considered first. The first match that succeeds
is used.

For example, the following expression maps URL locations in the form
.B http://example.com/foo/bar.xsd
to local files in the form
.BR bar.xsd :

.B %http://.+/(.+)%$1%

See also the REGEX AND SHELL QUOTING section below.

.IP "\fB\--location-regex-trace\fR"
Trace the process of applying regular expressions specified with
the
.B --location-regex
option. Use this option to find out why your regular expressions
don't do what you expected them to do.

.IP "\fB\--file-per-type\fR"
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:
.BR --type-file-regex ,
.BR --schema-file-regex,
and
.BR --file-list .

.IP "\fB\--type-file-regex \fIregex\fR"
Add
.I regex
to the list of regular expressions used to translate type names to file
names when the
.B --file-per-type
option is specified.
.I regex
is a perl-like regular expression in the form
.BI / pattern / replacement /\fR.
Any character can be used as a delimiter instead of
.BR / .
Escaping of the delimiter character in
.I pattern
or
.I replacement
is not supported. 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

.I namespace type-name

For example, the following expression maps type
.B foo
that is defined in the
.B http://example.com/bar
namespace to file name
.BR bar-foo :

.B %http://example.com/(.+) (.+)%$1-$2%

See also the REGEX AND SHELL QUOTING section below.

.IP "\fB\--type-file-regex-trace\fR"
Trace the process of applying regular expressions specified with
the
.B --type-file-regex
option. Use this option to find out why your regular expressions
don't do what you expected them to do.

.IP "\fB\--schema-file-regex \fIregex\fR"
Add
.I regex
to the list of regular expressions used to translate schema file names
when the
.B --file-per-type
option is specified.
.I regex
is a perl-like regular expression in the form
.BI / pattern / replacement /\fR.
Any character can be used as a delimiter instead of
.BR / .
Escaping of the delimiter character in
.I pattern
or
.I replacement
is not supported. 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 the absolute
filesystem path of a schema file and the result, including the directory
part, if any, is used to derive the
.B #include
directive paths as well as the generated C++ file paths. This option, along
with
.B --type-file-regex
are primarily used to place the generated files into subdirectories or to
resolve file name conflicts.

For example, the following expression maps schema files in the
.B foo/1.0.0/
subdirectory to the files in the
.B foo/
subdirectory. As a result, the
.B #include
directive paths for such schemas will be in the
.B foo/schema.hxx
form and the generated C++ files will be placed into the
.B foo/
subdirectory:

.B %.*/foo/1.0.0/(.+)%foo/$1%

See also the REGEX AND SHELL QUOTING section below.

.IP "\fB\--schema-file-regex-trace\fR"
Trace the process of applying regular expressions specified with
the
.B --schema-file-regex
option. Use this option to find out why your regular expressions
don't do what you expected them to do.

.IP "\fB\--file-list \fIfile\fR"
Write a list of generated C++ files to
.IR file .
This option is primarily useful in the file-per-type compilation mode
.RB ( --file-per-type )
to create a list of generated C++ files, for example, as a makefile fragment.

.IP "\fB\--file-list-prologue \fItext\fR"
Insert
.I text
at the beginning of the file list. As a convenience, all occurrences of the
\\n character sequence in
.I text
are replaced with new lines. This option can, for example, be used to assign
the generated file list to a makefile variable.

.IP "\fB\--file-list-epilogue \fItext\fR"
Insert
.I text
at the end of the file list. As a convenience, all occurrences of the
\\n character sequence in
.I text
are replaced with new lines.

.IP "\fB\--file-list-delim \fItext\fR"
Delimit file names written to the file list with
.I text
instead of new lines. As a convenience, all occurrences of the \\n character
sequence in
.I text
are replaced with new lines.

.IP "\fB\--generate-polymorphic\fR"
Generate polymorphism-aware code. Specify this option if you use substitution
groups or
.BR xsi:type .
Use the
.B --polymorphic-type
or
.B --polymorphic-type-all
option to specify which type hierarchies are polymorphic.

.IP "\fB\--polymorphic-type \fItype\fR"
Indicate that
.I type
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
.IR type .
The
.I type
argument is an XML Schema type name that can be optionally qualified
with a namespace in the
.IB namespace # name
form.

.IP "\fB\--polymorphic-type-all\fR"
Indicate that all types should be treated as polymorphic.

.IP "\fB\--generate-serialization\fR"
Generate serialization functions. Serialization functions convert
the object model back to XML.

.IP "\fB\--generate-inline\fR"
Generate simple functions inline. This option triggers creation of the
inline file.

.IP "\fB\--generate-ostream\fR"
Generate ostream insertion operators
.RB ( operator<< )
for generated types. This allows to easily print a fragment or the whole
object model for debugging or logging.

.IP "\fB\--generate-doxygen\fR"
Generate documentation comments suitable for extraction by the Doxygen
documentation system. Documentation from annotations is added to the
comments if present in the schema.

.IP "\fB\--generate-comparison\fR"
Generate comparison operators
.RB ( operator==
and
.BR operator!= )
for complex types. Comparison is performed memberwise.

.IP "\fB\--generate-default-ctor\fR"
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.

.IP "\fB\--generate-from-base-ctor\fR"
Generate constructors that expect an instance of a base type followed by all
required members.

.IP "\fB\--generate-detach\fR"
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.

.IP "\fB\--generate-wildcard\fR"
Generate accessors and modifiers as well as parsing and serialization code
for XML Schema wildcards
.RB ( any
and
.BR anyAttribute ).
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.

.IP "\fB\--generate-insertion \fIos\fR"
Generate data representation stream insertion operators for the
.I os
output stream type. Repeat this option to specify more than one stream
type. The ACE CDR stream
.RB ( ACE_OutputCDR )
and RPC XDR are recognized by the compiler and the necessary
.B #include
directives are automatically generated. For custom stream types use the
.B --hxx-prologue*
options to provide the necessary declarations.

.IP "\fB\--generate-extraction \fIis\fR"
Generate data representation stream extraction constructors for the
.I is
input stream type. Repeat this option to specify more than one stream
type. The ACE CDR stream
.RB ( ACE_InputCDR )
and RPC XDR are recognized by the compiler and the necessary
.B #include
directives are automatically generated. For custom stream types use the
.B --hxx-prologue*
options to provide the necessary declarations.

.IP "\fB\--generate-forward\fR"
Generate a separate header file with forward declarations for the types
being generated.

.IP "\fB\--generate-xml-schema\fR"
Generate a C++ header file as if the schema being compiled defines the
XML Schema namespace. In particular, the resulting file will have
definitions for all XML Schema built-in types. 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
.B --extern-xml-schema
option to include this file in the generated files for other schemas.

.IP "\fB\--extern-xml-schema \fIfile\fR"
Include a header file derived from
.I file
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
.B --generate-xml-schema
option to generate this header file.

.IP "\fB\--suppress-parsing\fR"
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.

.IP "\fB\--generate-element-type\fR"
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.

.IP "\fB\--generate-element-map\fR"
Generate a root element map that allows uniform parsing and serialization
of multiple root elements. This option is only valid together with
.BR --generate-element-type .

.IP "\fB\--generate-intellisense\fR"
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) does not require these workarounds. Support for
IntelliSense in Visual Studio 2003 (7.1) is improved with this option but
is still incomplete.

\"
\" NAMING CONVENTION
\"

.SH NAMING CONVENTION
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
.B --type-naming
and
.B --function-naming
options. A custom naming convention can be achieved using the
.BR --type-regex ,
.BR --accessor-regex ,
.BR --one-accessor-regex ,
.BR --opt-accessor-regex ,
.BR --seq-accessor-regex ,
.BR --modifier-regex ,
.BR --one-modifier-regex ,
.BR --opt-modifier-regex ,
.BR --seq-modifier-regex ,
.BR --parser-regex ,
.BR --serializer-regex ,
.BR --enumerator-regex ,
and
.B --element-type-regex
options.

The
.B --type-naming
option specifies the convention that should be used for naming C++ types.
Possible values for this option are
.B knr
(default),
.BR ucc ,
and
.BR java .
The
.B knr
value (stands for K&R) signifies the standard, lower-case naming convention
with the underscore used as a word delimiter, for example: foo, foo_bar.
The
.B ucc
(stands for upper-camel-case) and
.B java
values a synonyms for the same naming convention where the first letter
of each word in the name is capitalized, for example: Foo, FooBar.

Similarly, the
.B --function-naming
option specifies the convention that should be used for naming C++ functions.
Possible values for this option are
.B knr
(default),
.BR lcc ,
and
.BR java .
The
.B knr
value (stands for K&R) signifies the standard, lower-case naming convention
with the underscore used as a word delimiter, for example: foo(), foo_bar().
The
.B lcc
value (stands for lower-camel-case) signifies a naming convention where the
first letter of each word except the first is capitalized, for example: foo(),
fooBar(). The
.B java
naming convention is similar to the lower-camel-case one except that accessor
functions are prefixed with get, modifier functions are prefixed with set,
parsing functions are prefixed with parse, and serialization functions are
prefixed with serialize, for example: getFoo(), setFooBar(), parseRoot(),
serializeRoot().

Note that the naming conventions specified with the
.B --type-naming
and
.B --function-naming
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
.B --*-regex
options (discussed below) to perform further transformations on the names
that come from the schema.

The
.BR --type-regex ,

.BR --seq-modifier-regex ,
.BR --parser-regex ,
.BR --serializer-regex ,
.BR --enumerator-regex ,
and
.B --element-type-regex
options allow you to specify extra regular expressions for each name
category in addition to the predefined set that is added depending on
the
.B --type-naming
and
.B --function-naming
options. Expressions that are provided with the
.B --*-regex
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
.B --name-regex-trace
option allows you to trace the process of applying
regular expressions to names.

The value for the
.B --*-regex
options should be a perl-like regular expression in the form
.BI / pattern / replacement /\fR.
Any character can be used as a delimiter instead of
.BR / .
Escaping of the delimiter character in
.I pattern
or
.I replacement
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
.B --one-accessor-regex
(accessors with cardinality one),
.B --opt-accessor-regex
(accessors with cardinality optional), and
.B --seq-accessor-regex
(accessors with cardinality sequence) categories the
.B --accessor-regex
expressions are used as a fallback. For the
.BR --one-modifier-regex ,
.BR --opt-modifier-regex ,
and
.B --seq-modifier-regex
categories the
.B --modifier-regex
expressions are used as a fallback. For the
.B --element-type-regex
category the
.B --type-regex
expressions are used as a fallback.

The type name expressions
.RB ( --type-regex )
are evaluated on the name string that has the following format:

[\fInamespace  \fR]\fIname\fR[\fB,\fIname\fR][\fB,\fIname\fR][\fB,\fIname\fR]

The element type name expressions
.RB ( --element-type-regex ),
effective only when the
.B --generate-element-type
option is specified, are evaluated on the name string that has the following
format:

.I namespace  name

In the type name format the
.I namespace
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
.I namespace
part is empty but the space is still present. In the type name format after
the initial
.I name
component, up to three additional
.I name
components can be present, separated by commas. For example:

.B http://example.com/hello type

.B foo

.B foo,iterator

.B foo,const,iterator

The following set of predefined regular expressions is used to transform
type names when the upper-camel-case naming convention is selected:

.B /(?:[^ ]* )?([^,]+)/\\\\u$1/

.B /(?:[^ ]* )?([^,]+),([^,]+)/\\\\u$1\\\\u$2/

.B /(?:[^ ]* )?([^,]+),([^,]+),([^,]+)/\\\\u$1\\\\u$2\\\\u$3/

.B /(?:[^ ]* )?([^,]+),([^,]+),([^,]+),([^,]+)/\\\\u$1\\\\u$2\\\\u$3\\\\u$4/

The accessor and modifier expressions
.RB ( --*accessor-regex
and
.BR --*modifier-regex )
are evaluated on the name string that has the following format:

\fIname\fR[\fB,\fIname\fR][\fB,\fIname\fR]

After the initial
.I name
component, up to two additional
.I name
components can be present, separated by commas. For example:

.B foo

.B dom,document

.B foo,default,value

The following set of predefined regular expressions is used to transform
accessor names when the
.B java
naming convention is selected:

.B /([^,]+)/get\\\\u$1/

.B /([^,]+),([^,]+)/get\\\\u$1\\\\u$2/

.B /([^,]+),([^,]+),([^,]+)/get\\\\u$1\\\\u$2\\\\u$3/

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
.B java
naming convention is selected:

.B /(.+)/parse\\\\u$1/

\"
\" TYPE MAP
\"
.SH TYPE MAP
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
.B post_*
functions in parser skeletons corresponding to XML Schema types
as well as argument types for callbacks corresponding to elements
and attributes of these types.

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
.BR void .
By providing your own type maps you can override these predefined rules.
The format of the type map file is presented below:

.RS
.B namespace
.I schema-namespace
[
.I cxx-namespace
]
.br
.B {
.br
  (
.B include
.IB file-name ;
)*
.br
  ([
.B type
]
.I schema-type cxx-ret-type
[
.I cxx-arg-type
.RB ] ;
)*
.br
.B }
.br
.RE

Both
.I schema-namespace
and
.I schema-type
are regex patterns while
.IR cxx-namespace ,
.IR cxx-ret-type ,
and
.I cxx-arg-type
are regex pattern substitutions. All names can be optionally enclosed
in \fR" "\fR, for example, to include white-spaces.

.I schema-namespace
determines XML Schema namespace. Optional
.I cxx-namespace
is prefixed to every C++ type name in this namespace declaration.
.I cxx-ret-type
is a C++ type name that is used as a return type for the
.B post_*
functions. Optional
.I cxx-arg-type
is an argument type for callback functions corresponding to elements and
attributes of this type. If
.I cxx-arg-type
is not specified, it defaults to
.I cxx-ret-type
if
.I cxx-ret-type
ends with
.B *
or
.B &
(that is, it is a pointer or a reference) and
.B const
\fIcxx-ret-type\fB&\fR otherwise.
.I file-name
is a file name either in the \fR" "\fR or < > format and is added with the
.B #include
directive to the generated code.

The \fB#\fR character starts a comment that ends with a new line or end of
file. To specify a name that contains \fB#\fR enclose it in \fR" "\fR. For
example:

.RS
namespace http://www.example.com/xmlns/my my
.br
{
.br
  include "my.hxx";
.br

  # Pass apples by value.
  #
  apple apple;
.br

  # Pass oranges as pointers.
  #
  orange orange_t*;
.br
}
.br
.RE

In the example above, for the
.B http://www.example.com/xmlns/my#orange
XML Schema type, the
.B my::orange_t*
C++ type will be used as both return and argument types.

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:

.RS
include "my.hxx";
.br
apple apple;
.br

namespace http://www.example.com/xmlns/my
.br
{
.br
  orange "const orange_t*";
.br
}
.br
.RE


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
.B std::string
or
.B std::wstring
depending on the character type selected with the
.B --char-type
option
.RB ( char
by default).

The last predefined rule maps anything that wasn't mapped by previous
rules to
.BR void :

.RS
namespace .*
.br
{
.br
  .* void void;
.br
}
.br
.RE

When you provide your own type maps with the
.B --type-map
option, they are evaluated first. This allows you to selectively override
predefined rules.

.\"
.\" REGEX AND SHELL QUOTING
.\"
.SH REGEX AND SHELL QUOTING
When entering a regular expression argument in the shell command line
it is often necessary to use quoting (enclosing the argument in " "
or ' ') in order to prevent the shell from interpreting certain
characters, for example, spaces as argument separators and $ as
variable expansions.

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 " " for quoting you will get
a wrong result with POSIX shells if your expression contains $. The
standard way of dealing with this on POSIX systems is to use ' '
instead. Unfortunately, Windows shell does not remove ' '  from
arguments when they are passed to applications. As a result you may
have to use ' ' for POSIX and " " for Windows ($ is not treated as
a special character on Windows).

Alternatively, you can save regular expression options into a file,
one option per line, and use this file with the
.B --options-file
option. With this approach you don't need to worry about shell quoting.
