Filtering user comments

Currently my comments are filtered by the h-command which is fine but
I'd like to add some expections to it. Well, I dont need to use the
h-command but a system that would allow a few html tags and deny all
others would be perfect.

Is there such code out there somewhere that I could use? I tried to
google around but couldn't find anything. I also could do the whole
thing myself but the regexp bits are a bit too hard.

Instead of h try using sanitize it should escape the bad stuff like
script tags
