Kaboodle Bookmarklet - Method?

Hey,

I was just wondering if anyone had a more in depth concept on how the
Kaboodle Bookmarklet works or how to mimic the concept.

I know there would be some sore of page scraping. I've tried the
Kaboodle bookmarklet on many different pages and not all pages have
descriptive identifiers in the content or the class's/id's the
descriptions sit in. Yet in can still manage to find very relevant
content.

Suggestions or ideas ?
