Windows Phone WP7 Help parsing XML feed

I'm struggling to parse a Google feed. I have no problems with normal RSS but this slightly more complex ATOM based feed is not working for me with the same simple parsing code. How can I get to the entry elelemts?

The following code I am using does not work, it returns no collection, but works fine with RSS for getting <item> elements presumably becuase they have no attributes.

XElement _xml = XElement.Parse(response);
foreach (XElement value in _xml.Elements("entry"))
{
...
}

How can I get to the entry elements when they have a gd:etag="..."?

Any help appreciated.

--------------- SAMPLE OF THE FEED ----------------------

You should use Linq. Load the xml into an XDocument object and then run a Linq query against that for the entries that have gd:etag="".

XDocument feedXml = XDocument.Load(uriToFeed);
var feedInfo = from item in publicationsXml.Descendants("feed")
               select new Feed // this can be a class that has the properties 
                               // from each feed that you care about
               {
                 // code to retreive info you need from the item
                 ID = item.Element("id").Value,
                 //etc.
               };
