Website scraping - How can I load a 'partial' page?

[Roger Eller]

I have a webpage that I grab with LiveCode, then parse out what I need.
The data I keep is within the first 1/4th of the page.

Rather than loading the entire page into a variable or a browser object,
how can I load just the portion that I need and then stop the transmission
instead of wasting the time and bandwidth to load the entire page?
