These are generated by XSD from supermen.xsd. + Note also that we use the --generate-polymorphic command line option + and that we don't need to use --polymorphic-type to explicitly mark + types as polymorphic because this is automatically deduced by the + XSD compiler from the substitution groups used in the supermen.xsd + schema. + +driver.cxx + Driver for the example. 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 run the example on the sample XML instance document simply execute: + +$ ./driver instance.xml |
