This example shows how to use the C++/Parser mapping to construct
a custom in-memory object model from XML instance documents.
The example consists of the following files:
library.xsd
XML Schema which describes a library of books.
library.xml
Sample XML instance document.
library.hxx
Types that describe a library of books in C++. These are
hand-written.
library.map
Type map. It maps XML Schema types defined in library.xsd
to the C++ types defined in library.hxx.
library-pskel.hxx
library-pskel.ixx
library-pskel.cxx
Parser skeletons generated by the XSD compiler from library.xsd and
library.map using the following command line:
xsd cxx-parser --type-map=library.map library.xsd
Or if using Expat instead of Xerces-C++ as the underlying XML parser:
xsd cxx-parser --xml-parser=expat --type-map=library.map library.xsd
library-pimpl.hxx
library-pimpl.cxx
Parser implementations that construct the custom in-memory
object model from an XML instance using the types from
library.hxx. These are hand-written implementations of
the parser skeletons defined in library-pskel.hxx.
driver.cxx
Driver for the example. It first constructs a parser
instance from all the individual parsers found in
library-pimpl.hxx. In then invokes this parser instance
to parse the input file and produce the in-memory
object model. Finally, it prints the contents of the
in-memory object model to STDERR.
To compile and link the example manually from the command line we can use
the following commands (replace 'c++' with your C++ compiler name):
c++ -c library-pskel.cxx
c++ -c library-pimpl.cxx
c++ -c driver.cxx
c++ -o driver driver.o library-pskel.o library-pimpl.o -lxerces-c
Or if using Expat as the underlying XML parser:
c++ -o driver driver.o library-pskel.o library-pimpl.o -lexpat
To run the example on the sample XML instance document execute:
./driver library.xml
