我想解析这个文件并将每个事务标记属性作为treeview的根读取，例如Home将是treeview的根节点，然后URL标记值作为其子节点，所有事务和URL标记的含义相同以根节点登录，而不是相应的URL标记值作为其子节点。

Answer 1

你可以使用命令行调用为它创建xml的方案而不是cs-class：

xsd xml.xml
xsd xml.xsd /c

将生成xml.cs文件。您可以使用常见的xml序列化程序对其进行反序列化。

    XmlSerializer ser = new XmlSerializer(typeof(Performance));
    var t = ser.Deserialize(new XmlTextReader(@"C:\temp\xml.xml"));

反序列化后，您确实拥有具有树结构的普通c＃对象：

如果您在创建cs文件时遇到问题，请执行以下操作：

//------------------------------------------------------------------------------
// <auto-generated>
//     This code was generated by a tool.
//     Runtime Version:4.0.30319.42000
//
//     Changes to this file may cause incorrect behavior and will be lost if
//     the code is regenerated.
// </auto-generated>

using System.Xml.Serialization;

XmlDocument xml = new XmlDocument();
            xml.Load("E://session1.xml"); // suppose that myXmlString contains "<Names>...</Names>"
            string roots = xml.DocumentElement.Name;
            treeView1.Nodes.Add(roots);
            TreeNode ParentNode = new TreeNode();
            XmlElement root = xml.DocumentElement;

            if (root.HasAttribute("name"))
            {
                {
                    String name = root.GetAttribute("name");
                    ParentNode.Text = name;
                    treeView1.Nodes.Clear();
                    treeView1.Nodes.Add(ParentNode);
                }
            }
            //while(xml.)
            XmlNodeList xnList = xml.DocumentElement.SelectNodes("/transaction/request");
            foreach (XmlNode xn in xnList)
            {

                string url = xn["URL"].InnerText;
                ParentNode.Nodes.Add(url);
                treeView1.ExpandAll();
            }

上面提到的代码帮助生成带有第一个标记和标记值的树视图，但它不适用于第二个和第三个事务标记。它是正确的继续方式，否则我必须通过其他方式尝试它。

使用XML Linq。从这段代码开始。您可以在结果中使用您的代码。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);

            var results = doc.Descendants("transaction").Select(x => new
            {
                name = x.Attribute("name").Value,
                request = x.Elements("request").Select(y => new {
                    transaction = y.Attribute("transaction").Value,
                    URLs = y.Element("URL").Value
                }).ToList()
            }).ToList();
        }
    }
}

或使用此代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Xml;
using System.Xml.Linq;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
            const string FILENAME = @"c:\temp\test.xml";
        public Form1()
        {
            InitializeComponent();

            XDocument doc = XDocument.Load(FILENAME);
            TreeNode root = new TreeNode();
            treeView1.Nodes.Clear();

            foreach (XElement transaction in doc.Descendants("transaction"))
            {
                string name = transaction.Attribute("name").Value;
                TreeNode transactionNode = treeView1.Nodes.Add(name);

                foreach (XElement request in transaction.Elements("request"))
                {
                    string transactionName = request.Attribute("transaction").Value;
                    string URLs = request.Element("URL").Value;
                    string node = string.Format("Transaction : {0}, URL : {1}", transactionName, URLs);
                    transactionNode.Nodes.Add(node);
                }

            }

            treeView1.ExpandAll();
        }
    }
}
