Standalone Javascript layout engine?

Assuming I retrieved HTML content from a website (over which I have no control), and that content contains lots of Javascript code that's a significant part of what's actually rendered by a layout engine (e.g. WebView).

Is there a way I can render it myself?

For example, in the extreme case, suppose I am visiting a website that has almost nothing in its but displays very rich TEXT content, via a host of Javascript functions (which obviously results in HTML).

How do access/read that HTML result?

I am looking to do this on Android only.

Update, trying to provide more context to @abesto. If you go to facebook.com and copy/paste rendered content into a text file, you'll receive:

But if you look at the actual source (what you get in HttpResponse) you'll see much more monstrous text... mostly javascript.

I am only interested in the result of that Javascript. Any ideas how to accomplish this?

I think the answer is yes, but don't do that.

If I had to implement a solution for translating 'Facebook' to a mobile phone, I could set up a server, maybe on Amazon EC2 and run the browser there, using a browser automation solution, such as Watir to simulate the clicks and scrape the data off the page. I think it's too much to hope for that you could run that efficiently behind the scenes on the phone itself.

However, the better solution might be to use Firebug/Fiddler etc to reverse engineer the ajax calls being sent and find a way to get the underlying data? Or maybe you just need to reverse-engineer the JS :(.

It sounds like you want something like this :

http://jsconsole.com/

You basically load the url and mess with it. You just need to hook something into it to do it programmatically.

Take a look at their remote debugging explanation.

Since it's hooked upto to your android over a stream you can use any old PC technology you want to sniff the HTML.
