    var query=from x in xml.Descendants("dict") 
              where x.Parent.Name=="plist" 
              from y in x.Elements()
              where y.Value=="CFBundleDisplayName"
              select y.NextNode;
              
    var query1=from x in xml.Descendants("dict") 
              where x.Parent.Name=="plist" 
              from y in x.Elements()
              where y.Value=="CFBundleIconFiles"
              select y.NextNode;
}
