LINQ query problem

Question

Can\'t get any result in feeds. feedXML has the correct data.

XDocument feedXML = XDocument.Load(@\"http://search.twitter.com/search.atom?q=twitter\");

var feed         


        

Answer 1

If you look at the XML returned by the HTTP request, you will see that it has an XML namespace defined:

  tag:search.twitter.com,2005:search/twitter
  ...

XML is just like C#, if you use an element name with the wrong namespace, it is not considered to be the same element! You need to add the required namepsace to your query:

private static string AtomNamespace = "http://www.w3.org/2005/Atom";

public static XName Entry = XName.Get("entry", AtomNamespace);

public static XName Published = XName.Get("published", AtomNamespace);

public static XName Title = XName.Get("title", AtomNamespace);

var items = doc.Descendants(AtomConst.Entry)
                .Select(entryElement => new FeedItemViewModel()
                new {
                  Title = entryElement.Descendants(AtomConst.Title).Single().Value,
                  ...
                });
