Yes, yes, innerHTML is "the debil." Direct DOM manipulation is much to be preferred. It's faster, smells less, and gives you shiny white teeth. But innerHTML, when combined with XHR, can allow you to scrape data from the existing HTML pages of a site.

Wouldn't the XMLHTTPRequest be denied as cross site scripting?
I've used a similiar technique in a project of mine, and it only worked for pulling pages directly from the callers domain. As it should.

That's correct. You would use it to pull HTML from the current domain. As the article explains, you would use this in only certain circumstances, such as when you can't get the backend system to generate XML.
FlySwat replied ago:
Screen Scraping would be of rather limited use if you already have access to the domain.

Ah, FlySwat. Stay tuned for some of the interesting things you can do with screen scraping and bookmarklets.
