Importing Data from Website into App Lab

I have a student who is looking to import data that is collected from an external website and use it in a program he is creating. Before he gets too far I am wondering if this is even possible? The data is updated often and he wants to be able to pull from it for his App. He wants to know if he can make calls to the HTML ID Tags from the website (or if there is another way). Hopefully that makes sense! Anyone have any thoughts? Thanks!
