XmlDocument vs XElement

  var xmlstr = @"<xml>

<AppId>some_appid</AppId>

<CreateTime>1413192605</CreateTime>

<InfoType>component_verify_ticket</InfoType>

<ComponentVerifyTicket>some_verify_ticket</ComponentVerifyTicket>

</xml>";

            Stopwatch sw = Stopwatch.StartNew();

            for (int i = 0; i < 1000; i++)

            {

                XmlDocument doc = new XmlDocument();

                doc.XmlResolver = null;

                XmlNode root;

                doc.LoadXml(xmlstr);

                root = doc.FirstChild;

                var sEncryptMsg = root["ComponentVerifyTicket"].InnerText;

            }

            sw.Stop();

            var docts = sw.ElapsedMilliseconds;

            sw.Restart();

            for (int i = 0; i < 1000; i++)

            {

                XElement xe = XElement.Parse(xmlstr);

                var sEncryptMsg = xe.Element("ComponentVerifyTicket").Value;

            }

            sw.Stop();

            MessageBox.Show(docts + "," +sw.ElapsedMilliseconds.ToString());

XmlDocumentd的耗时大概是XElement 的4倍以上
