ASP.NET----使用XmlDocument读写节点属性

上篇文章中提到XML转换问题，有些朋友颇有疑问，后期答复详解，这次带来使用XmlDocument读写节点属性

using System;
using System.Xml;
namespace NET.MST.Tenth.UseXmlDocument
{
    partial class UseXmlDocument
    {
        static void Main(string[] args)
        {
            String path = "..\\..\\Test.xml";
            XmlDocument xml = new XmlDocument();
            xml.Load(path);
            Console.WriteLine("原先的XML文档是：");
            PringDocument(xml);
            Console.WriteLine("新建了节点之后：");
            AddNode(xml);
            PringDocument(xml);
            Console.WriteLine("修改了节点之后：");
            EditNode(xml);
            PringDocument(xml);
            Console.WriteLine("删除了节点之后：");
            DeleteNode(xml);
            PringDocument(xml);
            Console.Read();
        }
        /// <summary>
        /// 格式化输出XML文档
        /// </summary>
        /// <param name="xml">需要显示的文档</param>
        static void PringDocument(XmlDocument xml)
        {
            xml.Save(Console.Out);
            Console.Write("\r\n");
        }
    }
    partial class UseXmlDocument
    {
        /// <summary>
        /// 删除最后一个Book节点
        /// </summary>
        /// <param name="xml"></param>
        static void DeleteNode(XmlDocument xml)
        {
            XmlNode node = xml.DocumentElement;
            XmlNode remove = node.ChildNodes[node.ChildNodes.Count - 1];
            remove.Attributes.RemoveAt(0);
            node.RemoveChild(remove);
        }
    }
    partial class UseXmlDocument
    {
        /// <summary>
        /// 修改最后一个Book节点的节点值和属性
        /// </summary>
        /// <param name="xml"></param>
        static void EditNode(XmlDocument xml)
        {
            XmlNode node = xml.DocumentElement;
            XmlNode editnode = node.ChildNodes[node.ChildNodes.Count - 1];
            editnode.Attributes["name"].Value = "book4";
            editnode.SelectSingleNode("Auth").InnerText = "z4";
            editnode.SelectSingleNode("Date").InnerText = "2008-1-4";
        }
    }
    partial class UseXmlDocument
    {
        /// <summary>
        /// 增加节点、属性
        /// </summary>
        /// <param name="xml">被操作的XML文档</param>
        static void AddNode(XmlDocument xml)
        {
            //新建新Book节点
            XmlNode newnode = xml.CreateElement("Book");
            //新建name节点
            XmlAttribute newattribute = xml.CreateAttribute("name");
            newattribute.Value = "book3";
            newnode.Attributes.Append((XmlAttribute)newattribute);
            //新建Auth节点
            XmlNode auth = xml.CreateElement("Auth");
            auth.InnerText = "z3";
            //新建Date节点
            XmlNode date = xml.CreateElement("Date");
            date.InnerText = "2008-1-3";
            //添加所有新建的节点和属性
            newnode.AppendChild(auth);
            newnode.AppendChild(date);
            xml.DocumentElement.AppendChild(newnode);
        }
    }
