Just be warned with the above - this wont work with webpages that use AJAX as the result is taken on the initial load.  Not the subsequent data

If you have access to PHP, it's very easy.  Best, ~Ray
$html = file_get_contents('');
echo htmlentities($html);

The code from aherps is perhaps thestart point to begin with. 
All you need is to write a custom parser for html and identify your landmark tags in html source. From these tang you can read the inner html or text, attribute and other values.
Even you can manipulate ajax calls by identifying their url and attempt to download partial data from those urls.
