You can do it with a simple class describing the results that you want like this:
public class Entry
{
public string Published { get; set; }
public string PlayerUrl { get; set; }
public string ThumbnailUrl { get; set; }
public string ThumbnailHeight { get; set; }
public string ThumbnailWidth { get; set; }
public string ThumbnailTime { get; set; }
}
The elements with ":" are namespaces and the document itself is qualified with its own namespace. This looks like a feed from YouTube so I was able to parse the results with the following.
async Task getFeedAsync()
{
var client = new HttpClient();
var response = await client.GetStringAsync("https://gdata.youtube.com/feeds/api/videos");
var xdoc = XDocument.Parse(response);
XNamespace feed = "http://www.w3.org/2005/Atom";
XNamespace media = "http://search.yahoo.com/mrss/";
var results = from entry in xdoc.Descendants(feed + "entry")
select new Entry
{
Published = entry.Element(feed + "published").Value,
PlayerUrl = entry.Element(media + "group").Element(media + "player").Attribute("url").Value,
ThumbnailUrl = entry.Element(media + "group").Element(media + "thumbnail").Attribute("url").Value,
ThumbnailHeight = entry.Element(media + "group").Element(media + "thumbnail").Attribute("height").Value,
ThumbnailWidth = entry.Element(media + "group").Element(media + "thumbnail").Attribute("width").Value,
ThumbnailTime = entry.Element(media + "group").Element(media + "thumbnail").Attribute("time").Value
};
var Entries = results.ToList<Entry>();
}
