Language parsers

Question

I need to parse C #, Ruby and Python source code to generate some reports. I need to get a list of method names inside a class, and I need other information, such as using a global variable or something like that. Just parsing using RE can be a solution, but I expect a better (systematic) solution using parsers, if that is easily possible.

What parsers are provided for these languages?

In C # I found http://csparser.codeplex.com/Wikipage , but for the rest I found a group of parsers using these languages, but not their parsers.

Another answer to this poster suggests that Ruby is really hard to make out. C ++ is also famously hard to parse. DMS is used to parse another 30 other languages, including full C ++ in a number of dialects, so Ruby seems extremely doable. Howeever, DMS does not have a ready-made parser for Ruby.
