It will help you immensely if you can provide some examples of the messages you're trying to parse.  Without that, you'll get a lot fewer responses, and only then from people who happen to know what the output from an IRC channel looks like.

Needless to say, if you can provide some of the code that you've written (even if it isn't yet quite working), it will also help a great deal towards given you a quicker/better answer, since it will provide a context.
