Collecting NonForm Data from a page

[eluser]JoeLongstreet[/eluser]
I'm new to CodeIgniter and PHP in general, but I was looking for a way to collect information from a page that's not in a form field. All the tutorials I've seen collect information from input/textarea with a button press.

I've seen some helpers that use screen scraping. Is this the best option?

Any pointers or tutorial suggestions would be much appreciated.

Thanks,

Joe
