It first calls one of the parsing functions + that constructs the object model from the input XML file. It then + iterates over the text and elements in the content order to convert + the document to its plain text representation. The driver then adds + another paragraph of text and a link to the object model while showing + how to maintain the content order. Finally, it saves the modified + text back to XML to verify that the content order is preserved in + the output document. + +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 text.cxx +c++ -c driver.cxx +c++ -o driver driver.o text.o -lxerces-c + +To run the example on the sample XML instance document execute: + +./driver text.xml |
