.net里流模式操作xml小记

 1.XmlTextReader读XML文件

 

protected void Page_Load(object sender, EventArgs e) 
{ 
    string xmlFile = Server.MapPath("films.xml"); 
    XmlTextReader reader = new XmlTextReader(xmlFile); 
    while (reader.Read()) 
    { 
        if (reader.NodeType == XmlNodeType.Element) 
        { 
            if (reader.Name == "title") 
            { 
                Response.Write("<b>名称:</b>" + reader.ReadString()); 
            } 
            if (reader.Name == "author") 
            { 
                Response.Write("<b>导演:</b>" + reader.ReadString()); 
                Response.Write("<br />"); 
            } 
        } 
    } 
    reader.Close(); 
} 

films.xml:

 

<?xml version="1.0" encoding="utf-8" ?>  
<films> 
    <film> 
        <title>建国大业</title> 
        <author>黄建新</author> 
    </film> 
    <film> 
        <title>山楂树</title> 
        <author>张艺谋</author> 
    </film>     
</films> 

  2.XmlTextWriter写XML文件

 

protected void Page_Load(object sender, EventArgs e) 
{ 
    string xmlFile = Server.MapPath("new.xml"); 
    XmlTextWriter writer = new XmlTextWriter(xmlFile, null); 
    writer.WriteStartDocument(true); 
    writer.WriteStartElement("students"); 
    for (int i = 1; i <= 5; i++) 
    { 
        writer.WriteElementString("student", "学生" + i.ToString()); 
    } 
    writer.WriteEndElement(); 
    writer.WriteEndDocument(); 
    writer.Close(); 
    Response.Write("文档new.xml生成成功!"); 
} 

new.xml:

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