sceen grab

I am looking for a way to retrieve data from another website, parse through it and then display it as I would like to. Basically a screen grab from say espn.com, then I take the data that is there and form it to fit on my site. The catch here is that my target is an asp page that requires a login to get to the page I would like to get to. They do allow for the check here so i will be remembered next time, but will that work with a php screen grab. Any help at all would be appreciated. Thanks Matt
