Subject: extract information from a large text

I 'm new to ruby.I want to extract some useful information from a web
page to generate a RSS feeds.My first instinct is to provide a regular
expression like /sometext(.+?)sometext/, the problem is I can only get
the first match to this regex, how can I iterate over the multiple
matches?
And further more, this kind of naive solution, is it too slow to
search over a very large text?Because the performance requirement is
high.Is there a better way to do this?
