C++ classes hierarchy => to XSD schema? Anyone know tool or example?

Question

I know that I could convert XSD schema to C++ classes using codesynthesis mechanism. What about vice versa?

Lets say I have a very difficult class hierarchy in C++ and I would like to get XSD schema, so I could use it by any other language in future?

Answer 1

I don't know about any ready-made tool but clang provides an interface to the AST produced from C++ sources. It would be possible to create suitable tool on the basis of this this AST.

There is also gccxml which represents, at least, the declarations found in a C++ using XML. However, I haven't used gccxml and I don't know if it is still maintained.
