aa_macro.py provides the parse tree as a debugging facility if you provide the debug=True parameter on invocation of the module, or if you set it directly with obj.debug=True at some point prior to processing the content in question.
You can get a direct text-formatted report from the parse tree by calling obj.getdebug() after generation; or you can access the list the parse tree information is stored in directly at obj.devstack , which contains a list of tuples, where each tuple is arranged as follows:
The tuples are in parse order; that is, inside to outside, left to right.
