.net里流模式操作xml小记

 1.XmlTextReader读XML文件

1. protected void Page_Load(object sender, EventArgs e) 
2. { 
3.     string xmlFile = Server.MapPath("films.xml"); 
4.     XmlTextReader reader = new XmlTextReader(xmlFile); 
5.     while (reader.Read()) 
6.     { 
7.         if (reader.NodeType == XmlNodeType.Element) 
8.         { 
9.             if (reader.Name == "title") 
10.             { 
11.                 Response.Write("<b>名称:</b>" + reader.ReadString()); 
12.             } 
13.             if (reader.Name == "author") 
14.             { 
15.                 Response.Write("<b>导演:</b>" + reader.ReadString()); 
16.                 Response.Write("<br />"); 
17.             } 
18.         } 
19.     } 
20.     reader.Close(); 
21. } 

films.xml:

1. <?xml version="1.0" encoding="utf-8" ?>  
2. <films> 
3.     <film> 
4.         <title>建国大业</title> 
5.         <author>黄建新</author> 
6.     </film> 
7.     <film> 
8.         <title>山楂树</title> 
9.         <author>张艺谋</author> 
10.     </film>     
11. </films> 

  2.XmlTextWriter写XML文件

1. protected void Page_Load(object sender, EventArgs e) 
2. { 
3.     string xmlFile = Server.MapPath("new.xml"); 
4.     XmlTextWriter writer = new XmlTextWriter(xmlFile, null); 
5.     writer.WriteStartDocument(true); 
6.     writer.WriteStartElement("students"); 
7.     for (int i = 1; i <= 5; i++) 
8.     { 
9.         writer.WriteElementString("student", "学生" + i.ToString()); 
10.     } 
11.     writer.WriteEndElement(); 
12.     writer.WriteEndDocument(); 
13.     writer.Close(); 
14.     Response.Write("文档new.xml生成成功!"); 
15. } 

new.xml:

1. <?xml version="1.0" standalone="yes" ?>  
2. <students> 
3. <student>学生1</student>  
4. <student>学生2</student>  
5. <student>学生3</student>  
6. <student>学生4</student>  
7. <student>学生5</student>  
8. </students>
