            using (WebResponse Serviceres = request.GetResponse())
            {
                using (StreamReader rd = new StreamReader(Serviceres.GetResponseStream()))
                {
                    //reading stream  
                    var ServiceResult = rd.ReadToEnd();
                    XmlDocument xml = new XmlDocument();
                    xml.LoadXml(ServiceResult);
                    //  XmlNodeList xNodelst = xml.DocumentElement.SelectNodes("/DataSet/NewDataSet/Table");//reading node so that we can traverse thorugh the XML
                    // XmlNodeList XList = xml.SelectNodes("//*");
                    XmlNodeList xnList = xml.SelectNodes("/NewDataSet/Table");
                }
            }
