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 |
