It's sort of already been done with GCC-XML:

"The purpose of the GCC-XML extension is to generate an XML
description of a C++ program from GCC's internal representation. Since
XML is easy to parse, other development tools will be able to work
with C++ programs without the burden of a complicated C++ parser."
