Javascript - Screen scraping

[Ed999]

I've posted in this forum before about Javascript.

I use a simple javascript script, in a batch file, to download audio and video - radio and tv shows - from the BBC iPlayer.

Part of the script extracts data from the BBC's xml pages.

I now want to try extracting data from a html page. Can anyone point me to a javascript method for extracting data from an ordinary .htm or .html page?

I'm anxious to keep things simple, by having a javascript routine which I can include in a html page on my website, so I'm only interested in javascript solutions. Thanks.
