Re: Using regular expressions within a python script?

I ran into this same problem and discovered that some fields
have a
.replace method.  E.g.
something.Description().replace('<p>',''). That
was good enough for what I wanted.  Not sure if it works for
the body
text.

To speak from one's own experience: If you want to parse
HTML, use a
HTML parser  (e.g.
HTMLParser)

Look here: http://docs.py
