C# 解析XML「建议收藏」

大家好，又见面了，我是你们的朋友全栈君。

解析文件内容：

<?xml version="1.0" encoding="utf-8" ?>

<users>
  <user id="1001">
    <name>张三</name>
    <email>123456789@136.com</email>
    <phone>13400000000</phone>
  </user>
  <user id="1002">
    <name>李四</name>
    <email>123456789@126.com</email>
    <phone>15800000000</phone>
  </user>
</users>

解析代码：

static void ReadParseXml()
{
    XmlDocument xmlDoc = new XmlDocument();
    xmlDoc.Load("E:/Data/VisualStudio/C#/app001/ConsoleApp/App01/userlist.xml");
    //查找<users>
    XmlNode root = xmlDoc.SelectSingleNode("users");
    //获取到所有<users>的子节点
    XmlNodeList nodeList =root.ChildNodes;
    //遍历所有子节点
    foreach (XmlNode xn in nodeList)
    {
        XmlElement xe = (XmlElement)xn;
        XmlNodeList subList = xe.ChildNodes;
        foreach (XmlNode xmlNode in subList)
        {
            if ("name".Equals(xmlNode.Name))
            {
                Console.WriteLine("姓名：" + xmlNode.InnerText);
            }
            else if ("email".Equals(xmlNode.Name))
            {
                Console.WriteLine("邮箱：" + xmlNode.InnerText);
            }                  
        }            
    }
}



static void ReadParseXml2()
{
    XmlDocument xmlDoc = new XmlDocument();
    xmlDoc.Load("E:/Data/VisualStudio/C#/app001/ConsoleApp/App01/userlist.xml");
    //查找<users>
    XmlNode root = xmlDoc.SelectSingleNode("users");
    //获取到所有<users>的子节点
    XmlNodeList nodeList = xmlDoc.SelectSingleNode("users").ChildNodes;
    //遍历所有子节点
    foreach (XmlNode xn in nodeList)
    {
        XmlElement xe = (XmlElement)xn;
        Console.WriteLine("节点的ID为： " + xe.GetAttribute("id"));
        XmlNodeList subList = xe.ChildNodes;
        foreach (XmlNode xmlNode in subList)
        {
            Console.WriteLine(xmlNode.InnerText);
        }
    }
}
