title: How to parse an xml feed using python?
body: <p>I am trying to parse this xml (http://www.reddit.com/r/videos/top/.rss) and am having troubles doing so.  I am trying to save the youtube links in each of the items, but am having trouble because of the "channel" child node.  How do I get to this level so I can then iterate through the items?</p>
  
  <pre><code>#reddit parse
  reddit_file = urllib2.urlopen('http://www.reddit.com/r/videos/top/.rss')
  #convert to string:
  reddit_data = reddit_file.read()
  #close file because we dont need it anymore:
  reddit_file.close()
  
  #entire feed
  reddit_root = etree.fromstring(reddit_data)
  channel = reddit_root.findall('{http://purl.org/dc/elements/1.1/}channel')
  print channel
  
  reddit_feed=[]
  for entry in channel:   
      #get description, url, and thumbnail
      desc = #not sure how to get this
  
      reddit_feed.append([desc])
  </code></pre>
