Once you have an AST, you'll need to write a tree walker that emits your program as the transformed source. You might even have an intermediate tree walker doing tree transformations depending upon the complexity of your changes.

You might want to take a look at "Language Design Patterns" by Terrence Parr (Pragmatic Programmers). Chapter 11 addresses your type of program.

He mentions a tool, ANTLRMorph, that might be better suited for your problem.
