Cross-site scripting (XSS) defense

[johnzenger]

Is there a module (or, better yet, sample code) that scrubs
user-entered text to remove cross-site scripting attacks, while also
allowing a small subset of HTML through?

Contemplated application: a message board that allows people to use
<b>, <a href="">, <i> and so on, but does not allow any javascript,
vbscript, or other nasties.

I use Strip-o-Gram:

It is used quite a bit in Zope, but I believe it
will also stand on its own.
