This example shows how to use the Embedded C++/Hybrid mapping to parse
XML documents into an in-memory object model, modify this object model,
and serialize it back to XML.

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

library-pskel.hxx
library-pskel.cxx
library-pimpl.hxx
library-pimpl.cxx

library-pskel.hxx
library-pskel.cxx
library-pimpl.hxx
library-pimpl.cxx
  Object model (the first pair of files), parser skeletons (the
  second pair), parser implementations (the third pair), serializer
  skeletons (the fourth pair), and serializer implementations (the
  fifth pair). These files are generated by the XSD/e compiler from
  library.xsd. The --generate-parser, --generate-serializer, and 
  --generate-aggregate options were used to request the generation
  of the parsing and serialization code.

driver.cxx
  Driver for the example. It first calls the parser that constructs
  the object model from the input XML file. It then prints the content
  of the object model to STDERR. Finally, the driver modifies the
  object model and calls the serializer to serialize it back to XML.

To run the example on the sample XML instance document simply execute:

$ ./driver library.xml

The example reads from STDIN if input file is not specified:

$ ./driver <library.xml
