Removing HTML Tags

[Johnstone, Colin]

Gidday all,
 
When using our CMS (Interwoven Teamsite) I want to remove from any textarea any html 
tags that I don't want content contributors to use. On in particular is the font tag. 
Can one use a regex to remove these?
 
I guess Im looking for a regex to remove anything between the font tags e.g <font>and 
</font>. Of course their could be anynumber of attributes in the openning font tag.
 
Any help appreciated
Thanking you in anticipation
