[Zope] Fighting htmllib in external method

[Jonothan Farr]

Try using a StringIO object as your file.

import htmllib
import formatter
from cStringIO import StringIO

def index(self, html):
    file = StringIO()
    fmtr = formatter.AbstractFormatter(formatter.DumbWriter(file))
    p = htmllib.HTMLParser(fmtr)
    p.feed(html)
    file.seek(0)
    return file.read()
