Not if you want to adhere to best practices. XSS is not something you  
can remove. It's the result of sloppy programming.

On my blog, XSS is talked about a lot, so many of the comments might  
appear to be XSS attacks. I haven't (yet) had a vulnerability in my  
comment code, despite being a constant target for attack, and despite  
the fact that I don't remove any part of anyone's comment.

There's a lot of misinformation out there, so tread carefully.
