this can do it nicely.

+      Bleach is an HTML sanitizing library that escapes or strips markup and
+      attributes based on a white list. Bleach can also linkify text safely,
+      applying filters that Django's urlize filter cannot, and optionally
+      setting rel attributes, even on links already in the text.
+
+      Bleach is intended for sanitizing text from untrusted sources. If you
+      find yourself jumping through hoops to allow your site administrators
+      to do lots of things, you're probably outside the use cases. Either
+      trust those users, or don't.
