Xdocument and linq - doesn't cycle thru the elements

Question

Given the xml from the request (with XXX replaced by whatever user wanted), cant really figure out why it's not returning 2 test objects to the list as it should.

String YouTubeXML = new WebClient().DownloadString("http://gdata.youtube.com/feeds/api/users/XXXXXXXXX/uploads?orderby=published");
XDocument xDoc = XDocument.Parse(YouTubeXML);

List<dynamic> videos = (from i in xDoc.Descendants("entry")
                        select new
                        {
                            //Just declaring something random
                            Title = i.Element("id").Value

                        }).ToList<dynamic>();

And the XML structure looks something like this:

<feed xmlns="http://www.w3.org/2005/Atom" xmlns:media="http://search.yahoo.com/mrss/" xmlns:openSearch="http://a9.com/-/spec/opensearchrss/1.0/" xmlns:gd="http://schemas.google.com/g/2005" xmlns:yt="http://gdata.youtube.com/schemas/2007">

What could possible be going wrong? The XML is being received and parsed, so it's the query that is not working.

Answer 1

You're missing the fact, that XML uses namespaces, so your query has to use namespaces too:

var ns = XNamespace.Get("http://www.w3.org/2005/Atom");
var videos = (from i in xDoc.Root.Elements(ns + "entry")
              select new
              {
                  Title = (string)i.Element(ns + "id")
              }).ToList();
