This example shows how to use the C++/Tree mapping to parse several
XML documents while reusing the underlying XML parser and caching the
schemas used for validation.
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
library.cxx
C++ types that represent the given vocabulary and a set of parsing
functions that convert XML instance documents to a tree-like in-memory
object model.
These files are generated by the XSD compiler from library.xsd using
the following command line:
xsd cxx-tree library.xsd
driver.cxx
Driver for the example. It first sets up the Xerces-C++ DOM parser
and caches the library.xsd schema for validation. It then performs
ten iterations that parse the input file to a DOM document using
the DOM parser and call one of the parsing functions that constructs
the object model from this DOM document. On each iteration the driver
prints a number of books in the 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++ -DXSD_CXX11 -c library.cxx
c++ -DXSD_CXX11 -c driver.cxx
c++ -o driver driver.o library.o -lxerces-c
Note that we need to define the XSD_CXX11 preprocessor macro since the
source code includes libxsd headers directly.
To run the example on the sample XML instance document execute:
./driver library.xml library.xsd
