Fpc's fcl-passrc package gives you a parser that produces an abstract syntax tree of the units that have been parsed.
(pparser, pastree units)

There are people that use this to analyse their code. It is used to create webservices from existing interfaces.
The documentation is produced from the abstract syntax tree.

Maybe it is useful for your purposes as well.
