[Zope] RSS feed: post-processing?

[Chris Withers]

Sorry Eva,

You'll need to explain your problem more succintly for people to be able 
to help. If you really do need to scrape the urls from the text, then a 
combination of python's xml handling and regular expressions is probably 
what you're after, best done in an external method and not a python 
script...

cheers,

Chris
