Access openSearch:totalResults using feedparser
===

How can I retrieve the openSearch:totalResults attribute using feedparser?

I have a blogger API result which looks  a bit like this (I have cut out some stuff to make it compact here)

     <feed xmlns='http://www.w3.org/2005/Atom'
      xmlns:openSearch='http://a9.com/-/spec/opensearch/1.1/'
      xmlns:gd='http://schemas.google.com/g/2005'
      gd:etag='W/"CUYMQ348fyp7ImA9WB9UFkU."'>

     <generator version='7.00'
       uri='http://www.blogger.com'>Blogger</generator>
     <openSearch:totalResults>1</openSearch:totalResults>
     <openSearch:startIndex>1</openSearch:startIndex>

Currently, I do something like 

    req = urllib.urlopen(url)
    urlContent = req.read()            
    feed = feedparser.parse(urlContent)
    print feed.feed['openSearch_totalResults']

I get an error with the above code that the attribute does not exist. I have confirmed that the feed parser has the namespace by running
    
    print feed['namespaces']

which gives me

    {'': u'http://www.w3.org/2005/Atom', u'gd': u'http://schemas.google.com/g/2005', u'thr': u'http://purl.org/syndication/thread/1.0', u'openSearch': u'http://a9.com/-/spec/opensearchrss/1.0/'}
