title: pubDate RSS parsing weirdness with Beautifulsoup/Python
body: <p>I'm trying to parse an RSS/Podcast feed using Beautifulsoup and everything is working nicely except I can't seem to parse the 'pubDate' field.</p>
  
  <pre><code>data = urllib2.urlopen("http://www.democracynow.org/podcast.xml")
  dom = BeautifulStoneSoup(data, fromEncoding='utf-8')
  items = dom.findAll('item');
  
  for item in items:
      title = item.find('title').string.strip()
      pubDate = item.find('pubDate').string.strip()
  </code></pre>
  
  <p>The title gets parsed fine but when it gets to pubDate, it says:</p>
  
  <p>Traceback (most recent call last):
    File "", line 2, in 
  AttributeError: 'NoneType' object has no attribute 'string'</p>
  
  <p>However, when I download a copy of the XML file and rename 'pubDate' to something else, then parse it again, it seems to work. Is pubDate a reserved variable or something in Python?</p>
  
  <p>Thanks,</p>
  
  <p>g</p>
