Is it possible to get information with just link?

Hello all, i have a question. Is there possible to get a data (for example some word in website) and then use the sentence to our own JSP page?
To make clearly, example : www.facebook.com , is it possible to get the word "Sign Up" (in the middle right of page) ? How to get that?
Thanks!

In my opinion, yes, it's possible. I've already made one. Using some Web Parser Library like JSoup. But it's really hard(maybe I was just at the beginning of that). But JSoup is really easy to use.

JSoup? what is the different with RSS? Could you show the code JSoup work? Because my advisor told me to use RSS but i never know RSS before :D
