获取xml节点值

Question

  <?xml version="1.0" encoding="gbk" ?> 
  <soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
  <soapenv:Body>
  <ns3:MoSOAPRespBody xmlns:ns3="http://smses.zjseol.com.cn/esesms/">
  <ns3:message>
  <id>id</id> 
  <result>处理结果</result> 
  </ns3:message>
  </ns3:MoSOAPRespBody>
  </soapenv:Body>
  </soapenv:Envelope>怎么样取得id和result这两个节点的值？

Answer 1

    XmlDocument doc = new XmlDocument();
    doc.Load("xx.xml");    XmlNodeList elemList = doc.GetElementsByTagName("id");
    for (int i=0; i < elemList.Count; i++)
    {   
      Console.WriteLine(elemList[i].InnerXml);
    }
    elemList = doc.GetElementsByTagName("result");
    for (int i=0; i < elemList.Count; i++)
    {   
      Console.WriteLine(elemList[i].InnerXml);
    }   

Answer 2

<?xml version="1.0" encoding="gbk" ?> 
  <soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> 
  <soapenv:Body> 
  <ns3:MoSOAPRespBody xmlns:ns3="http://smses.zjseol.com.cn/esesms/"> 
  <ns3:message> 
  <id>id </id> 
  <result>处理结果 </result> 
  </ns3:message> 
  </ns3:MoSOAPRespBody> 
  </soapenv:Body> 
  </soapenv:Envelope> 是传递过来的一段字符串，不是一个xml文件

Answer 3

XML操作专题：http://www.bbs180.com/topictag-34.aspx读写等都有。

Answer 4

doc.load("xml文件字符串")提示错误：
路径中具有非法字符。 
？？

Answer 5

 我是这么做的！不知道还有什么好的么！ private void GetXmlData(string Path)
        {
            DataTable dt = new DataTable();            if (Path != string.Empty)
            {
                DataSet ds = new DataSet();
                try
                {
                    ds.ReadXml(Path));
                    dt = ds.Tables["message"];                }
                catch
                {
                    throw new BusinessException("XML文件有问题，请导入正确的XML文件");
                }
                            }        }得到的dt就是你要的id 和 result 的记录表！

Answer 6

XmlDocument xml = new XmlDocument();            string source = "<?xml version=\"1.0\" encoding=\"gbk\" ?>" +
                                        "<soapenv:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" " +
                                        "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\"> " +
                                        "<soapenv:Body> " +
                                        "<ns3:MoSOAPRespBody xmlns:ns3=\"http://smses.zjseol.com.cn/esesms/\">" +
                                        "<ns3:message>" +
                                        "<id>id </id> " +
                                        "<result>处理结果 </result> " +
                                        "</ns3:message> " +
                                        "</ns3:MoSOAPRespBody> " +
                                        "</soapenv:Body> " +
                                        "</soapenv:Envelope> ";            byte[] bytes = Encoding.Default.GetBytes(source);
            MemoryStream ms = new MemoryStream(bytes, 0, bytes.Length);
            xml.Load(ms);
这是把你的字符串转成XmlDocument的...
然后你再从xmlDocument里取值就成了

Answer 7

try:            string str = @"<?xml version=""1.0"" encoding=""gbk"" ?>
  <soapenv:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soapenv=""http://schemas.xmlsoap.org/soap/envelope/"">
  <soapenv:Body>
  <ns3:MoSOAPRespBody xmlns:ns3=""http://smses.zjseol.com.cn/esesms/"">
  <ns3:message>
  <id>id </id>
  <result>处理结果 </result>
  </ns3:message>
  </ns3:MoSOAPRespBody>
  </soapenv:Body>
  </soapenv:Envelope> ";
            XmlDocument doc = new XmlDocument();
            doc.LoadXml(str);
            foreach (XmlNode node in doc.GetElementsByTagName("id"))
                Console.WriteLine(node.InnerXml);
            foreach (XmlNode node in doc.GetElementsByTagName("result"))
                Console.WriteLine(node.InnerXml);

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Xml;namespace WindowsApplication5
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();            System.Xml.NameTable NT = new System.Xml.NameTable();
            XmlNamespaceManager XNM = new XmlNamespaceManager(NT);
            XNM.AddNamespace("soapenv", "http://schemas.xmlsoap.org/soap/envelope/");
            XNM.AddNamespace("ns3", "http://smses.zjseol.com.cn/esesms/");
            XmlDocument Doc = new XmlDocument();
            Doc.Load(@"c:\1.xml");
            XmlNode Node = Doc.SelectSingleNode("/soapenv:Envelope/soapenv:Body/ns3:MoSOAPRespBody/ns3:message/id", XNM);
            MessageBox.Show("id=" + Node.InnerText);
            Node = Doc.SelectSingleNode("/soapenv:Envelope/soapenv:Body/ns3:MoSOAPRespBody/ns3:message/result", XNM);
            MessageBox.Show("result=" + Node.InnerText);
        }
    }
}

Answer 9

使用XPATH应该比较简单吧
 XmlDocument xml = new XmlDocument();
  xml.Load(Server.MapPath(Xml的路径);
  XmlNode xmlnode=xml.SelectSingleNode("id");
  string value=xmlnode.InnerText;
这样就得到你想要的值了，当然也可以使用linq

Answer 10

    XmlDocument doc = new XmlDocument();
    doc.Load("xx.xml");    XmlNodeList elemList = doc.DocumentElement.GetElementsByTagName("id");
    for (int i=0; i < elemList.Count; i++)
    {   
      Console.WriteLine(elemList[i].InnerXml);
    }
    elemList = doc.DocumentElement.GetElementsByTagName("result");
    for (int i=0; i < elemList.Count; i++)
    {   
      Console.WriteLine(elemList[i].InnerXml);
    }
