Try ElementTree instead; there is an implementation included with Python
2.5, documentation at http://effbot.org/zone/element.htm and another
implementation available at http://codespeak.net/lxml/
import xml.etree.cElementTree as ET
rssurl = 'http://www.jabber.org/news/rss.xml'
rssdata = urllib2.urlopen(rssurl).read()
rssdata = rssdata.replace('&', '&') # ouch!
tree = ET.fromstring(rssdata)
for item in tree.getiterator('item'):
Note that this particular RSS feed is NOT a well formed XML document - I
had to replace the & with & to make the parser happy.
