For an +alternative approach that employes type customization see the +custom/wildcard example. + +The example consists of the following files: + +email.xsd + XML Schema which describes a simple email format with the + extensible envelope type. + +email.xml + Sample email message. + +email.hxx +email.ixx +email.cxx + C++ types that represent the given vocabulary, a set of parsing + functions that convert XML instance documents to a tree-like in-memory + object model, and a set of serialization functions that convert the + object model back to XML. These are generated by XSD from email.xsd. + Note that the --generate-wildcard option is used to request the + wildcard mapping. + +driver.cxx + Driver for the example. It first calls one of the parsing functions + that constructs the object model from the input file. It then prints + the content of the object model to STDERR. Next the driver creates a + reply email which is then serialized to XML. + +To run the example on the sample XML instance document simply execute: + +$ ./driver email.xml diff --git a/xsd-examples/cxx/tree/wildcard/buildfile b/xsd-examples/cxx/tree/wildcard/buildfile new file mode 100644 index 0000000..5bc63c5 --- /dev/null +++ b/xsd-examples/cxx/tree/wildcard/buildfile @@ -0,0 +1,30 @@ +# file : cxx/tree/wildcard/buildfile +# license : not copyrighted - public domain + +import libs = libxsd%lib{xsd} +import libs += libxerces-c%lib{xerces-c} + +./: exe{driver} doc{README} + +exe{driver}: {hxx cxx}{* -email} {hxx ixx cxx}{email} $libs + +exe{driver}: xml{email}: test.input = true + +<{hxx ixx cxx}{email}>: xsd{email} $xsd +{{ + diag xsd ($<[0]) # @@ TMP + + $xsd cxx-tree --std c++11 \ + --generate-inline \ + --generate-wildcard \ + --generate-serialization \ + --root-element message \ + --output-dir $out_base \ + $path($<[0]) +}} + +cxx.poptions =+ "-I$out_base" + +# Define XSD_CXX11 since we include libxsd headers directly. +# +cxx.poptions += -DXSD_CXX11 diff --git a/xsd-examples/cxx/tree/wildcard/driver.cxx b/xsd-examples/cxx/tree/wildcard/driver.cxx new file mode 100644 index 0000000..146a2d9 --- /dev/null +++ b/xsd-examples/cxx/tree/wildcard/driver.cxx @@ -0,0 +1,159 @@ +// file : cxx/tree/wildcard/driver.cxx +// copyright : not copyrighted - public domain + +#include <string> +#include <memory> // std::unique_ptr +#include <cstring> // std::memcpy +#include <iostream> + +#include <xercesc/dom/DOM.hpp> +#include <xercesc/util/PlatformUtils.hpp> + +#include "email.hxx" + +// The following string class keeps us sane when working with Xerces. +// Include it after the generated header in order to get only char or +// wchar_t version depending on how you compiled your schemas. +// +#include <xsd/cxx/xml/string.hxx> + +using std::cerr; +using std::endl; +using std::string; + +int +main (int argc, char* argv[]) +{ + if (argc != 2) + { + cerr << "usage: " << argv[0] << " email.xml" << endl; + return 1; + } + + using namespace xercesc; + + int r (0); + + // The Xerces-C++ DOM objects that will be used to store the + // content matched by wildcards "out-live" the call to the + // parsing function.
