I don't know about that, but I think you can work the other way
around, using a bit of regular expression magic:

import re
existing = [wikipedia.Page(wikipedia.getSite(), pname).title() for
pname in re.findall(r"title=(.*?)&amp;action=edit", fullsourcetext)]

def exists(page):
     return page.title() in existing
This works fine!  I didn't know that titles could be encoded in Page(). There are already some regexes in my code. Thank you!
