On-the-fly page validation

I wonder if this is possible. I've been dabbling with JavaScript a little recently, in order to produce The Twaddle's Expletatron and this seems like something that should be possible with JS:

I want a script that can load up a given remote page (internally - I don't want to display the page, just to extract info from it), look at an element on that page with a given id, and return its class as a variable.

What's this got to do with validation? Well say the remote page was and the given id was result. Then, if the returned variable is valid (i.e. the class of that element is valid) you've got a valid page; if the returned variable isn't valid you haven't.

So, you could, using JavaScript, whack in a Valid XHTML logo if, and only if, the page is actually valid. If you like, you could throw in an Invalid! image if the page is not valid.

I know it's possible to refer to an element by its id; I know it's possible to get the content of that element. I don't know if it's possible to get an element's class, and I'm guessing it's slightly impossible to do all this for another, remote page.

It'd be nice though.
