This example shows how to save/load the object model to/from a custom format using the Boost serialization library as an example. You will need the Boost serialization library[1] installed in order to build and run this example. [1] http://www.boost.org The example consists of the following files: library.xsd XML Schema which describes a library of books. library.xml Sample XML instance document. boost-archive-extraction.hxx boost-archive-insertion.hxx Boost archive insertion and extraction operators for fundamental types. You will need to provide a similar set of operators for your own stream types. library-prologue.hxx Contains a number of #include directives that are inserted into the generated code by the XSD compiler. The included files are: boost/archive/text_oarchive.hpp, boost/archive/text_oarchive.hpp, boost-archive-insertion.hxx, and boost-archive-insertion.hxx. library.hxx library.cxx C++ types that represent the given vocabulary as well as Boost archive insertion and extraction operations. These are generated by the XSD compiler from library.xsd. The --hxx-prologue-file option is used to insert the contents of the library-prologue.hxx file into the generated header file. The --generate-insertion and --generate-extraction options are used to generate the insertion and extraction operations for text_oarchive and text_iarchive types. 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 text_oarchive and loads it back from text_iarchive. Additionally, it prints the resulting text representation as well as the content of the object model before saving it to text_oarchive and after loading it from text_iarchive. To run the example on the sample XML instance document simply execute: $ ./driver library.xml
