C#修改XML的简单例子
接上一篇《C#写XML的简单例子》
这个例子要修改XML文件中结点的属性和和元素的文本
1 原xml文件 bookstore.xml
<?xml version="1.0" encoding="gb2312"?>
<bookstore>
<book genre="love" ISBN="1234123">
<title>who am i </title>
<author>who</author>
<price>999</price>
</book>
<book leixing="music" ISBN="56756">
<title>CS从入门到精通</title>
<author>候捷</author>
<price>222</price>
</book>
</bookstore>
2 program.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{
//实例化一个XmlDocument对象
XmlDocument xmlDoc = new XmlDocument();
//实例对象读取要写入的XML文件
xmlDoc.Load("bookstore.xml");
//获取bookstore节点的所有子节点
XmlNodeList nodeList = xmlDoc.SelectSingleNode("bookstore").ChildNodes;
//遍历所有子节点
foreach (XmlNode xn in nodeList)
{
//将子节点类型

public class Cls_XML
{
#region 创建xml文件

MSXML2::IXMLDOMDocumentPtr pDoc;
MSXML2::IXMLDOMElementPtr xmlRoot ;
// 创建DOMDocument对象
HRESULT hr = pDoc.CreateInstance(__uuidof(MSXML2::DOMDocument40));

这个例子要把bookstore.xml文件增加一条book记录
1 bookstore.xml
<?xml version="1.0" encoding="gb2312"?>
<bookstore>
<book genre="love" ISBN="1234123">
<title>who am i </title>
<author>who</author>
