ASP中利用execute实现动态包含文件的方法

Function include(filename)
Dim re,content,fso,f,aspStart,aspEnd
set fso=CreateObject("Scripting.FileSystemObject")
set f=fso.OpenTextFile(server.mappath(filename))
content=f.ReadAll
f.close
set f=nothing
set fso=nothing
set re=new RegExp
re.pattern="^\s="
aspEnd=1
aspStart=inStr(aspEnd,content,"<%")+2
do while aspStart>aspEnd+1
 Response.write Mid(content,aspEnd,aspStart-aspEnd-2)
 aspEnd=inStr(aspStart,content,"%\>")+2
 Execute(re.replace(Mid(content,aspStart,aspEnd-aspStart-2),"Response.Write "))
 aspStart=inStr(aspEnd,content,"<%")+2
loop
Response.write Mid(content,aspEnd)
set re=nothing
End Function

Dim objAbc 
Set objAbc = New clsAbc 
objAbc.output 
Set objAbc = Nothing 

Dim strAbc,objAbc 
strAbc = "Test" 
Server.Execute("sub.asp") 
Response.Write strAbc 
Set objAbc = New clsAbc 
objAbc.output 
Set objAbc = Nothing 

strAbc = "Execute" 
Class clsAbc 
 Public Function output 
 Response.Write "Class" 
 End Function 
End Class
