ASP四个小技巧，抓取网页：GetBody，字节转字符BytesToBstr，正则表达式测试方法，生成静态页

Function GetBody(weburl) 
    '创建对象
    Dim ObjXMLHTTP
    Set ObjXMLHTTP=Server.CreateObject("MSXML2.serverXMLHTTP")
    '请求文件,以异步形式
    ObjXMLHTTP.Open "GET",weburl,False
    ObjXMLHTTP.send
    While ObjXMLHTTP.readyState <> 4
        ObjXMLHTTP.waitForResponse 1000
    Wend
    '得到结果
     GetBody=ObjXMLHTTP.responseBody
    '释放对象
     Set ObjXMLHTTP=Nothing
End Function

Function BytesToBstr(body,Cset)
        dim objstream
        set objstream = Server.CreateObject("adodb.stream")
        objstream.Type = 1
        objstream.Mode =3
        objstream.Open
        objstream.Write body
        objstream.Position = 0
        objstream.Type = 2
        objstream.Charset = Cset
        BytesToBstr = objstream.ReadText 
        objstream.Close
        set objstream = nothing
End Function
