How to access Gmail Atom feed using Zend Libraries (PHP)?

I have worked out the oauth authentication etc.

Don't quite know how to access it. Searched the Zend docu开发者_StackOverflowmentation but couldn't find it..

Use SimplePie for parsing RSS or Atom feeds.

Use Zend_Feed -> http://framework.zend.com/manual/en/zend.feed.html
