如何从xml文件中读取单个节点值

嗨，我想从xml获取值，但它显示节点null。

这是我的xml文件。

   MailingGUID 0aa2b2e3-7afa-4002-ab2f-9eb4cbe33ae7   OrderRef 52186   

我想得到“MailingGUID”的价值。

这是我尝试过的代码：

  private void readXML() { XmlDocument xml = new XmlDocument(); // You'll need to put the correct path to your xml file here xml.Load(Server.MapPath("~/XmlFile11.xml")); // Select a specific node XmlNode node = xml.SelectSingleNode("result/data/value"); // Get its value string name = node.InnerText; } 

请告诉我如何获得MailingGUID值。

谢谢

更新：我认为你的模式可能有问题，我删除了对它们的引用，你的代码运行正常。 我试过这个：

 const string str = "MailingGUID0aa2b2e3-7afa-4002-ab2f-9eb4cbe33ae7OrderRef52186"; var xml = new XmlDocument(); xml.LoadXml(str); xml.DocumentElement.SelectSingleNode("/result/data/value").InnerText

Node childNode = list.item(i); System.out.println("MailingGUID : " + childNode.getTextContent()); }

 xml.LoadXml(sResponse); XmlNodeList Nnodes = xml.SelectNodes("/api_result/entries_success"); foreach (XmlNode Nnode in Nnodes) { string entries_success = Nnode["numto"].InnerText; LabelES.Text += entries_success + ","; }
