On Windows you may need to install a third-party +library which provides the XDR API. + +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 as well as data + representation stream insertion and extraction operations. + + These files are generated by the XSD compiler from library.xsd using + the following command line: + + xsd cxx-tree --generate-ostream --generate-comparison \ + --generate-insertion 'XDR' --generate-extraction 'XDR' library.xsd + + Note that the --generate-insertion and --generate-extraction options + are used to generate the insertion and extraction operations for XDR + stream. + +driver.cxx + Driver for the example. It first calls one of the parsing functions + that constructs the object model from the input XML file. It then + saves the object model to the XDR representation and loads it back. + Additionally, it prints the content of the object model before saving + it to the XDR representation and after loading it from the XDR + representation. + +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.cxx +c++ -c driver.cxx +c++ -o driver driver.o library.o -ltirpc -lxerces-c + +To run the example on the sample XML instance document execute: + +./driver library.xml |
