问题描述

我有以下格式的xml文件：

我想解析该文件并读取每个交易标签属性作为Treeview的根，例如，Home将是Treeview的根节点，然后将URL标记值作为其子节点，并且所有交易和URL标记的相同之处意味着以root身份登录节点，而不是各自的URL标记值作为其子节点。

您可以使用命令行创建xml方案，然后创建cs类： 

xsd xml.xml
xsd xml.xsd /c

这将产生xml.cs文件。 您可以使用常见的xml序列化器反序列化它。 

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

反序列化之后，您确实具有带有树结构的普通c＃对象：

在此处输入图片说明

如果您在创建cs文件时遇到问题，则为：

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();
            }

上面提到的代码可帮助ne生成具有第一个标签和标签值的树状视图，但不适用于第二个和第三个交易标签。这是继续进行的正确方法，还是我必须通过其他方法进行尝试。

使用XML Linq。 从此代码开始。 您可以对结果使用代码。 

 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();
        }
    }
}
