LINQ TO XML Parse RSS Feed - rss

Question

I'm trying to parse an RSS feed using LINQ to Xml
This is the rss feed:
http://www.surfersvillage.com/rss/rss.xml
My code is as follows to try and parse
List<RSS> results = null;
XNamespace ns = "http://purl.org/rss/1.0/";
XNamespace rdf = "http://www.w3.org/1999/02/22-rdf-syntax-ns#";
XDocument xdoc = XDocument.Load("http://www.surfersvillage.com/rss/rss.xml");
results = (from feed in xdoc.Descendants(rdf + "item")
orderby int.Parse(feed.Element("guid").Value) descending
let desc = feed.Element("description").Value
select new RSS
{
Title = feed.Element("title").Value,
Description = desc,
Link = feed.Element("link").Value
}).Take(10).ToList();
To test the code I've put a breakpoint in on the first line of the Linq query and tested it in the intermediate window with the following:
xdoc.Element(ns + "channel");
This works and returns an object as expect
i type in:
xdoc.Element(ns + "item");
the above worked and returned a single object but I'm looking for all the items
so i typed in..
xdoc.Elements(ns + "item");
This return nothing even though there are over 10 items, the decendants method doesnt work either and also returned null.
Could anyone give me a few pointers to where I'm going wrong? I've tried substituting the rdf in front as well for the namespace.
Thanks

You are referencing the wrong namespace. All the elements are using the default namespace rather than the rdf, so you code should be as follow:
List<RSS> results = null;
XNamespace ns = "http://purl.org/rss/1.0/";
XDocument xdoc = XDocument.Load("http://www.surfersvillage.com/rss/rss.xml");
results = (from feed in xdoc.Descendants(ns + "item")
orderby int.Parse(feed.Element(ns + "guid").Value) descending
let desc = feed.Element(ns + "description").Value
select new RSS
{
Title = feed.Element(ns + "title").Value,
Description = desc,
Link = feed.Element(ns + "link").Value
}).Take(10).ToList();
