How to get a certain value in this XML file using XDocument?
===

    <item>
     <title>Lorem Ipsum</title>
     <media:group>
       <media:content url = "http://www.sample.com" rate = "0" />
       <media:content url = "http://www.sample1.com" rate = "1" />
       <media:content url = "http://www.sample2.com" rate = "2" />
     </media:group>
    </item>

How do I get this value: 

> http://www.sample2.com?

I tried using this code:

    var query = from i in loadedData.Descendants("item")
     select new Site
     {
      Title = (string)i.Element("title"),
      Url = (string)i.Element(serv + "group").Elements(media + "content").Last()
     };
     site = query.ToList();

but the value of Url is "".
I also have this:

    private static readonly XNamespace media = "http://www.sampleX.com/";
