It's also quite difficult to insert code exactly where you want, because you do notknow the order in which the xml trees are defined then parsed.

I think it depends on what you're writing from the XML, are you
generating just constants (like the #define) or also new classes for

If it's just constants why don't you do a generation from XML -> ini
or something similar and then parse it in the C++ properly, then it
would be very easy to do?

You could also parse the XML in the first place but probably that's
harder given your requirements, but I don't think that an ini file
would be a problem, or would it?
