This example shows how to handle the xsi:type attributes and substitution
groups when they are used on root elements. For general coverage of XML
Schema polymorphism handling in the Embedded C++/Parser mapping see the
polymorphism example.
The example consists of the following files:
supermen.xsd
XML Schema which describes supermen instance documents.
person.xml
superman.xml
batman.xml
Sample XML instance documents.
supermen-pskel.hxx
supermen-pskel.cxx
Parser skeletons generated by the XSD/e compiler from supermen.xsd.
Note the use of the --generate-polymorphic command line option.
supermen-pimpl-mixin.hxx
supermen-pimpl-mixin.cxx
supermen-pimpl-tiein.hxx
supermen-pimpl-tiein.cxx
Parser implementations (using either mixin or tiein parser reuse
style) that print the XML data to STDOUT.
driver.cxx
Driver for the example. It implements a custom document parser
that determines which XML Schema type is being parsed and uses
the corresponding parser implementation. The driver first
constructs a parser instance from all the individual parsers
found in one of supermen-pimpl-*.hxx. In then invokes this parser
instance to parse the input file.
To run the example on the sample XML instance documents simply execute:
$ ./driver person.xml
$ ./driver superman.xml
$ ./driver batman.xml
The example reads from STDIN if input file is not specified:
$ ./driver <person.xml
$ ./driver <superman.xml
$ ./driver <batman.xml
