XmlDocument doc = new XmlDocument();
doc.LoadXml(sreturn);

XmlNode xNode = doc.SelectSingleNode("LisCallResponse/ResponseHead/Success");//取is_success节点的值
string is_success = xNode.InnerText;

                  <ResponseHead>

                            <Success>Y</Success>

                            <Msg>保存成功</Msg>

                  </ResponseHead>

                  <ResponseBody>

                  </ResponseBody>
