[Zope] Malicious HTML

I wish to allow users to enter comments into my database which are then viewable thru the browser. Is there a Zope function that I can pass their text thru to remove all HTML? ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.com/dynamo - The Homebuilt Dynamo http://www.compkarori.com/dbase - The dBase bulletin
