Hi Folkert,
getName() should work for namedDecl only; to get type names, you need to
work differently.
I suggest you have a look at:
http://clang.llvm.org/doxygen/TypePrinter_8cpp_source.html
http://clang.llvm.org/doxygen/ASTDumper_8cpp_source.html
http://clang.llvm.org/doxygen/StmtDumper_8cpp_source.html
They print/dump the AST. I would say it's the best place to look (and
reimplement) to print a xml.
Thanks,
