Grab specific Web content?

Hi everyone, I am looking to find out how to grab a specific content on a particular Website and put it on my Website. Of course, I will get permissions before doing so. Any ideas? I have found a sample ASP script that shows how to grab the entire page, but certain sections of the page. Any help would be appreciated, thankyou!

The ASP script below grabs the entire Webpage. How do you grab only the desire content within that page?

<%
Response.Buffer = True
Dim objXMLHTTP, xml

' Create an xmlhttp object:
Set xml = Server.CreateObject("Microsoft.XMLHTTP")
' Or, for version 3.0 of XMLHTTP, use:
' Set xml = Server.CreateObject("MSXML2.ServerXMLHTTP")

' Opens the connection to the remote server.
xml.Open "GET", "http://www.yahoo.com", False

' Actually Sends the request and returns the data:
xml.Send

'Display the HTML both as HTML and as text
Response.Write "<h1>The HTML text</h1><xmp>"
Response.Write xml.responseText
Response.Write "</xmp><p><hr><p><h1>The HTML Output</h1>"

Response.Write xml.responseText


Set xml = Nothing
%>
