导读：复制代码代码如下:

url="http://www.csdn.net/"
wstr=getHTTPPage(url)
start=Newstring(wstr,"资源精选")
over=Newstring(wstr,"<div class=""friendlink"">")
body=mid(wstr,200,500)

res

复制代码代码如下:

url="http://www.csdn.net/"
wstr=getHTTPPage(url)
start=Newstring(wstr,"资源精选")
over=Newstring(wstr,"<div class=""friendlink"">")
body=mid(wstr,200,500)

response.write body

Function getHTTPPage(url)
dim objXML
set objXML=createobject("MSXML2.XMLHTTP")'定义
objXML.open "GET",url,false'打开
objXML.send()'发送
If objXML.readystate<>4 then '判断文档是否已经解析完，以做客户端接受返回消息
exit function
End If
getHTTPPage=bBytesToBstr(objXML.responseBody)'返回信息，同时用函数定义编码
set objXML=nothing'关闭
if err.number<>0 then err.Clear
End Function

Function Newstring(wstr,strng)
Newstring=Instr(lcase(wstr),lcase(strng))
if Newstring<=0 then Newstring=Len(wstr)
End Function

Function bBytesToBstr(body)
dim objstream
set objstream = CreateObject("adodb.stream")
objstream.Type = 1
objstream.Mode =3
objstream.Open
objstream.Write body
objstream.Position = 0
objstream.Type = 2
objstream.Charset = "gb2312"
'转换原来默认的UTF-8编码转换成GB2312编码，否则直接用XMLHTTP调用有中文字符的网页得到的将是乱码
bBytesToBstr = objstream.ReadText
objstream.Close
set objstream = nothing
end Function

Function BytesToBstr(body)
dim objstream
set objstream = CreateObject("adodb.stream")
objstream.Type = 1
objstream.Mode =3
objstream.Open
objstream.Write body
objstream.Position = 0
objstream.Type = 2
objstream.Charset = "utf-8"
'转换原来默认的UTF-8编码转换成GB2312编码，否则直接用XMLHTTP调用有中文字符的网页得到的将是乱码
BytesToBstr = objstream.ReadText
objstream.Close
set objstream = nothing
end Function
