I can't think of a proper way of capturing just the data I need

First remove the data you don't need, et voilą!

You'll have to be more specific than that, we can't guess what is useful information for you. I can't even understand how you're supposed to read your data. See How do I post a question effectively? Be aware that you shouldn't expect to be given a fully functional solution, but rather advice, and maybe corrections. So you'll have to show some work.
