【XML操作】XMLTextWriter 创建、读取XML文档

 1             //创建XmlTextWriter类的实例对象
 2              XmlTextWriter textWriter = new XmlTextWriter("D:\\introduce1.xml",null);
 3             //设置格式，对元素内容进行缩进
 4              textWriter.Formatting = Formatting.Indented;
 5             //书写版本为“1.0”的XML声明
 6              textWriter.WriteStartDocument();
 7             //写出在名称和文本之间带有空格的处理指令
 8             string PItext = "type = 'text/xsl' href = 'book.xsl' ";
 9             textWriter.WriteProcessingInstruction("xml-stylesheet", PItext);
10             //增加指定名称和可选属性的DocType声明
11             textWriter.WriteDocType("学生",null,null,"<!ENTITY sex '男'>");
12             //增加注释
13             textWriter.WriteComment("XML注释");
14             //开始创建元素
15             textWriter.WriteStartElement("学生");
16             //创建属性
17             textWriter.WriteAttributeString("专业","计算机");
18             textWriter.WriteAttributeString("日期","2011-05-19");
19             //创建元素
20             textWriter.WriteElementString("姓名","好大一棵草");//创建元素1
21             textWriter.WriteStartElement("性别"); //创建元素2
22             textWriter.WriteEntityRef("sex");  //创建对上面实体的引用，显示时自动替换为：男
23             textWriter.WriteEndElement();
24             textWriter.WriteElementString("年龄","24");
25             //写CData信息
26             textWriter.WriteCData("年龄大了，该找女朋友了！");
27             //关闭根
28             textWriter.WriteEndElement();
29             textWriter.WriteEndDocument();
30             //最后写XML文件，并关闭textWriter
31             textWriter.Flush();
32             textWriter.Close();
33             Response.Write("写入成功");

 1             //创建一个XmlTextReader类的对象并调用Read方法来读取文件
 2             XmlTextReader textReader = new XmlTextReader("D:\\introduce1.xml");
 3 
 4             //节点非空这执行循环体
 5             textReader.Read();
 6             while (textReader.Read())
 7             {
 8             }
 9             //得到当前节点类型，执行相应处理
10             XmlNodeType nType = textReader.NodeType;
11             switch (nType )
12             {
13                 case XmlNodeType.XmlDeclaration:
14                     break;
15                 case XmlNodeType.Comment:
16                     break;
17                 case XmlNodeType.Attribute:
18                     break;
19                 case XmlNodeType.Element:
20                     break;
21                 case XmlNodeType.DocumentType:
22                     break;

24                     break;
25             }
26             //读取该元素的各种属性值
27             textReader.MoveToElement();
28             Response.Write("Name:" +textReader.Name);
29             Response.Write("Base URI:" + textReader.BaseURI);
