'ASP获取远程网页指定内容开始

Dim wstr,str,url,start,over,dtime

a="开始内容" 'ASP获取目标网页内容开始标记

b="结束内容" 'ASP获取网页内容结束标记

url="http://sc.jb51.net/"

wstr=getHTTPPage(url)

start=Newstring(wstr,a)

over=Newstring(wstr,b)

body=mid(wstr,start,over-start)

response.write ""&body&"" '输出获取到的网页内容

'ASP获取远程网页指定内容结束

%>

上面的代码可以获取指定网页的内容，如果是全部获取就更简单了

核心代码:

代码如下:

'ASP获取远程网页指定内容开始

Dim wstr,str,url,start,over,dtime

url="http://sc.jb51.net/"

wstr=getHTTPPage(url)

body=wstr
