请问是哪个类...怎么用...谢谢了~!!!

XmlWriter

[qimini]

==================== From MSDN 2003

Input

data1|data2|data3|data4|data5

and you would like to transform it to :

Output

<data>
<item> data1 </item>
<item> data2 </item>
<item> data3 </item>
<item> data4 </item>
<item> data5 </item>
</data>

A method is created to tokenize the data in the file into individual data tokens. Each call to this function returns one of the data elements. The method takes in a StreamReader.


[C#]
public static String NextToken(StreamReader stream)
{
int temp = stream.Read();
String t1 = "";
while(temp != -1 && temp != (int)'|')
{
t1 += (char)temp;
temp = stream.Read();
}
return t1;
}

The code iterates through until there are no data tokens remaining; inserting each token into an XML document. This is done in the Main function, which takes two command line arguments. The first argument is the file to read from, the second is the file to write to. The comments within the code provide a description of the actions taking place.

[C#]
using System;
using System.IO;
using System.Xml;

namespace TextFiletoXml
{

class TextFiletoXml
{
public static String file;
public static StreamReader stream;
public static XmlTextWriter xwriter;
public static String val;
public static String NextToken(StreamReader stream)
{
int temp = stream.Read();
String t1 = "";
while(temp != -1 && temp != (int)'|')
{
t1 += (char)temp;
temp = stream.Read();
}

return t1;

}

public static void Main(string[] args)
{
file = args[0];

//Create a new stream representing the file we are
//reading from.
stream = new StreamReader(file, true);

//Create a new XmlTextWriter.
xwriter = new XmlTextWriter(args[1],System.Text.Encoding.UTF8);
//Write the beginning of the document including the
//document declaration. Standalone is true.

xwriter.WriteStartDocument(true);

//Write the beginning of the "data" element. This is
//the opening tag to our data

xwriter.WriteStartElement("data","www.alpineskihouse.com");

// Get the first data element from the file.
val = NextToken(stream);

//create a new element with each data token from //the stream.
while(val != "")
{

xwriter.WriteElementString("item","www.alpineskihouse.com", val);
val = NextToken(stream);
}
//End the "data" element.
xwriter.WriteEndElement();

//End the document
xwriter.WriteEndDocument();

//Flush the xml document to the underlying stream and
//close the underlying stream. The data will not be
//written out to the stream until either the Flush()
//method is called or the Close() method is called.
xwriter.Close();
}
}
}

给你一个简洁的步骤：
1、创建一个XMLDocument对象，用于载入存储信息的XML文件；
XmlDocument xdoc=new XmlDocument();
xdoc.Load(Server.MapPath("XML文件名.xml"));

2、创建一个新的主节点，并将它添加到跟节点下：
XmlElement parentnode=xdoc.CreateElement("MainNode");
xdoc.DocumentElement.PrependChild(parentnode);

3、创建所有用于存储信息的子节点:
XmlElement node1=xdoc.CreateElement("node1");
XmlElement node2=xdoc.CreateElement("node2");
......................

4、将上面创建的各个存储信息的节点添加到主节点下但并不包含最终的值：
parentnode.AppendChild(node1);
parentnode.AppendChild(node2);
...........................

5、将要添加的文本信息添加到各个节点中去：
node1.AppendChild("----文本信息---");
node2.AppendChild("----文本信息---");

6、保存存储信息的XML文件
xdoc.Save(Server.MapPath("xml文件名.xml"));

按照上面的方法创建的 xml文件将具有如下格式：
<?xml version="1.0" encoding="gb2312"?>
<mainnode>
<node1>....</node1>
<node2>.....</node2>
</mainnode>
