asp读取数据库中的信息存储生成XML文件的例子

这里是一个asp读取数据库中的信息存储生成XML文件的例子，这种效果通常应用于接口文件
把下面的asp程序保存为一个asp文件即可，注意一下里面的表名和字段名

<!-- #include file="adovbs.inc" --> 
<% 
' Constants file included above. 
' 如果文件存在则删除 
Dim objFSO 
Set objFSO = Server.CreateObject("Scripting.FileSystemObject") 
If objFSO.FileExists(Server.MapPath("db_xml.xml")) Then 
objFSO.DeleteFile Server.MapPath("db_xml.xml") 
End IF 
Set objFSO = Nothing 
'变量声明 
Dim cnnXML ' ADO connection 
Dim rstXML ' ADO recordset 
'创建数据连接对象 
Set cnnXML = Server.CreateObject("ADODB.Connection") 
' 这是连接access数据库的例子: 
'cnnXML.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _ 
' & Server.MapPath("db_scratch.mdb") & ";" 
' 下面以Sqlserver为例子讲解: 
cnnXML.Open "Provider=SQLOLEDB;Data Source=10.2.1.214;" _ 
& "Initial Catalog=samples;User Id=samples;Password=password;" _ 
& "Connect Timeout=15;Network Library=dbmssocn;" 
Set rstXML = Server.CreateObject("ADODB.Recordset") 
Set rstXML = cnnXML.Execute("SELECT * FROM scratch ORDER BY id;") 
Response.Write "<p>Saving data as XML...</p>" & vbCrLf 
' 保存至xml格式. 
rstXML.Save Server.MapPath("db_xml.xml"), adPersistXML 
' 关闭对象、释放资源 
rstXML.Close 
Set rstXML = Nothing 
cnnXML.Close 
Set cnnXML = Nothing 
Response.Write "<p>XML file written...</p>" & vbCrLf 
Response.Write "<p>Click <a href=""db_xml.xml"">here</a> to view the file.</p>" & vbCrLf 
%>
