regenerating analyzed c++ code

Hello,

I am looking for an application that can parse c++, store it in a
AST, and regenerate the original c++ code. Obviously, the interesting
part would be to apply some modification to the AST before regenerating.

For example, I want to remove all constructors that match a certain
pattern (first argument contains the word Foo), from classes that are
derived from class Bar.

Would the synopsis parser be suitable for something like this? It seems
there is no C++ formatter...

Or maybe you can suggest some other project that would be suitable for 
such tasks?

Kind regards,

Maarten
