This example shows how to use the Embedded C++/Parser mapping
to construct a custom in-memory object model from XML instance
documents.

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
  Types that describe a library of books in C++. These are
  hand-written.

library.map
  Type map. It maps XML Schema types defined in library.xsd
  to C++ types defined in library.hxx.

library-pskel.hxx
library-pskel.ixx
library-pskel.cxx
  Parser skeletons generated by XSD/e from library.xsd and
  library.map (passed with the --type-map option).

library-pimpl-mixin.hxx
library-pimpl-mixin.cxx

library-pimpl-tiein.hxx
library-pimpl-tiein.cxx
  Parser implementations (using either mixin or tiein parser
  reuse style) that construct the custom in-memory object model
  from an XML instance using types from library.hxx. These are
  hand-written implementations of the parser skeletons defined
  in library-pskel.hxx.

driver.cxx
  Driver for the example. It first constructs a parser
  instance from all the individual parsers found in one of
  library-pimpl-*.hxx. In then invokes this parser instance
  to parse the input file and produce the in-memory object
  model. Finally, it prints the content of the object model
  to STDERR.

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
