What am I doing wrong here? Trying to parse xml into object using linq

I am trying to parse but its not working:

code

            Windows.Data.Xml.Dom.XmlDocument _serviceResponse = new Windows.Data.Xml.Dom.XmlDocument();
            _serviceResponse.LoadXml(response);

            System.Xml.Linq.XElement xle = System.Xml.Linq.XElement.Parse(response); //this works and in the intermediate windows this has all the elements correctly parsed.
            var device = xle.Element("device"); // this is null
            var iconList = xle.Element("iconList"); // also null
            var icons = from query in iconList.Descendants("icon")
                        select new Icon
                        {
                            MimeType = (string)query.Element("mimeType"),
                            Url = (string)query.Element("url"),
                            Height = (int)query.Element("height"),
                            Width = (int)query.Element("width"),
                            Depth = (int)query.Element("depth"),
                        };

            foreach (Icon icon in icons)
            {
                string path = icon.Url; // collection is empty so never gets here
            }

the xml is:
