[Dia2code-general] a custom code generator - looking for help getting started

[Srinivas N. <ned...@cs...>]

hello I am interested in generating an XML representation from Dia UML 
digrams in a custom format. I took a look at the Dia2Code source for 
inspiration. I notice that its written in C. What do most people use for 
writing a code generator? I wondered if you could give me some pointers 
about how to get started - do you recommend XSL or a regular programming 
language, is there a DTD available, what are the gotchas I need to worry 
about, etc

Any help you could give is much appreciated

thanks
