Thanks for the hint. I was just looking at the getParents() method :-)
Quick question: is getParents(childNode) *always* the parent (i.e.,
immediate parent, not ancestor) of childNode?

I gather this was the reason something like -dump-xml was dropped as a
CFE action. At the moment, I am working on a toy tool. It is nowhere
close to being production ready.
If someone in the community could mentor me for e.g., GSoC, I could give
this a more serious shot. Ultimately, like you say, this is a continuous
(and not one-time) effort that requires keeping track of upstream
changes in Clang AST. Nonetheless, I offer help for an initial prototype
at the very least.

Is anyone else in the list considering using clang -ast-dump towards a
non-clang tool e.g., IDE integration or some such?
