   protected void Button1_Click(object sender, EventArgs e)
        {

            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(Server.MapPath("books.xml"));

 

            XmlNode root = xmlDoc.SelectSingleNode("books");//查找<books>
            XmlElement xe1 = xmlDoc.CreateElement("book");//创建一个<book>节点
            //xe1.SetAttribute("author", "李红");//设置该节点author属性
            //xe1.SetAttribute("isbn", "2-3631-4");//设置该节点ISBN属性

            XmlElement xesub0 = xmlDoc.CreateElement("author");
            xesub0.InnerText = "齐志超";
            xe1.AppendChild(xesub0);

            XmlElement xesub4 = xmlDoc.CreateElement("date");
            xesub4.InnerText = "2012-12-21";
            xe1.AppendChild(xesub4);

            XmlElement xesub1 = xmlDoc.CreateElement("name");
            xesub1.InnerText = "W3C从入门到精通";//设置文本节点
            xe1.AppendChild(xesub1);//添加到<book>节点中

            XmlElement xesub2 = xmlDoc.CreateElement("publisher");
            xesub2.InnerText = "河软CSDN乐知学院";
            xe1.AppendChild(xesub2);
            XmlElement xesub5 = xmlDoc.CreateElement("isbn");
            xesub5.InnerText = "978-7-310-12341-8";
            xe1.AppendChild(xesub5);

            XmlElement xesub3 = xmlDoc.CreateElement("price");
            xesub3.InnerText = "100.00";
            xe1.AppendChild(xesub3);

 

            root.AppendChild(xe1);//添加到<books>节点中
            xmlDoc.Save(Server.MapPath("books.xml"));
