How to get the contents of a link

I have a question when I use piwik to some statistics of websites. How to get the contents of a link? For example: TOM I want to get the value of this TOM to do some work. But I cannot find a good way to get the TOM in your api.Could you please give me some suggetions? I know that piwik can get the title of a page, which I don’t really need. The contents of this link is more important for me. I will be very appriciate for it if you can help me solve this question. Thanks a lot!
