I found myself wanting a similar scraper a couple years ago for looking for
job postings hidden behind similar javascript silliness that took forever
to manually check. Never got around to it, though.

"Selenium" looks to be a possible alternative to htmlunit, might be easier
to use?

I'm still interested in what you come up with :)
