这是一个把数据库里的数据生成XML格式，你稍微改一下就可以用在文本文件了。
<%@
Import
Namespace="System.Data"

<%@
Import
Namespace="System.Data.SqlClient"
%>
<html>
<head>
<script
language="C#"
runat="server">
public
DataView
Source;
public
DataSet
ds;
public
bool
getSchema,
getData;
public
void
Submit_Click(Object
sender,
EventArgs
evt)
{
if
(IsPostBack)
{
SqlConnection
myConnection
=
new
SqlConnection(ConnectString.Value);
SqlDataAdapter
myCommand
=
new
SqlDataAdapter(myText.Value,
myConnection);
ds
=
new
DataSet();
myCommand.Fill(ds,
"表");
Source
=
new
DataView(ds.Tables[0]);
getSchema
=
GetSchema.Checked;
getData
=
GetData.Checked;
MyDataGrid.DataSource=Source;
MyDataGrid.DataBind();
}
}
</script>
</head>

用C#来做。要用XmlTextWriter向TXT文件中写内容。
using
System.Xml;
using
System.Text;
XmlTextReader
xmlReader
=
null;
xmlReader
=
new
XmlTextReader(mDocument);
//mDocument参数为xml文档名字
while(xmlReader.Read())
{
if(xmlReader.NodeType
==
XmlNodeType.Element)
{
while(xmlReader.MoveToNextAttribute())
{
//用XmlTextWriter类将xmlReader.Name和xmlReader.Value写入HTML做
//相应的处理
}
if(xmlReader.IsEmptyElement)
{
}
else
{
}
}
else
if(xmlReader.NodeType
==
XmlNodeType.EndElement)
{
//做自己的处理
}
else
if(xmlReader.NodeType
==
XmlNodeType.Text)
{
if
(xmlReader.Value.Length
!=
0)
{
//将xmlReader.Value
写入TXT中的处理
}
}
}
//end
of
~while(xmlReader.Read())
