Use code generator for parsing XML

[jhkluiver]

The parsing of XML is now done manual, this is error prone and labor intensive.

It's been my understanding that implementors tend to use a code generator to parse the XML. Maybe we can get a list of those who do and those who don't.

I'm referring to the C2SIM reference implementation. To avoid this confusing each project should have its own repository or there should be a label for each project.
