title: feedparser attribute error
body: <p>I'm trying to retrieve some news from the BBC rss feed and save certain parts locally in xml (althought this code only prints it). I seem to be able to retrieve everything I want except for the pubDate. I get the error </p>
  
  <pre><code>"File "/Library/Python/2.7/site-packages/feedparser.py", line 416, in __getattr__
  raise AttributeError, "object has no attribute '%s'" % key
  AttributeError: object has no attribute 'pubDate'"
  </code></pre>
  
  <p>I'm not sure why as everything else I've wanted to retrieve hasn't caused any problems. Here is the code:</p>
  
  <pre><code>import feedparser
  import xml.etree.cElementTree as ET
  from xml.dom import minidom
  
  BBCHome = feedparser.parse ('http://feeds.bbci.co.uk/news/rss.xml')
  
  
  def prettify(elem):
  
      rough_string = ET.tostring(elem, 'utf-8')
      reparsed = minidom.parseString(rough_string)
      return reparsed.toprettyxml(indent="  ")
  
  root = ET.Element('root')
  
  for story in BBCHome.entries:
      item = ET.SubElement(root,'item')
      title = ET.SubElement(item,'title')
      title.text = story.title
      # why doesn't pubDate work?
      pubDate = ET.SubElement (item,'pubDate')
      pubDate.text = story.pubDate
      description = ET.SubElement(item,'description')
      description.text = story.description
      link = ET.SubElement(item,'link')
      link.text = story.link
      print prettify(root)
  </code></pre>
  
  <p>Reading this page : <a href="https://pythonhosted.org/feedparser/namespace-handling.html" rel="nofollow">https://pythonhosted.org/feedparser/namespace-handling.html</a>
  I think it might have something to do with namespaces but tbh I don't really understand.
  I've looked at the raw feed and it seems like just another sub element of item similar to description or title.</p>
  
  <p>If I could find out how to fix this and why it wasn't working it would be greatly appreciated.
  Thanks.</p>
