screen scraping message boards

Hi all,
I'm trying to scrap (screen scraping) some message board
(e.g. yahoo finance, or any forum, etc.)
I'm trying to use ruby to do so, but still don't know how
to go over messages in the same html page and extract them into file

thanks in advance
J.

Hpricot is pretty nifty for parsing html
