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. Finally, the driver serializes + the object model back to XML. + +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 supermen.cxx +c++ -c driver.cxx +c++ -o driver driver.o supermen.o -lxerces-c + +To run the example on the sample XML instance document execute: + +./driver supermen.xml |
