How do I capture a live html page?

How do I capture a live html page?

I am new to jQuery. My background is C++ and C#.

Once I have the html using selectors and filters is not hard to understand.

My problem is understanding how to capture a live html page in jQuery and assign the page to an object which I can then use to extract information using basic selector and filter functions.

Any small bit of code would be helpful.

Thanks,
