Moved xpath into boostrap java

And removed complex-find while at it.

Submitting to @bootstraponline for review.

I'm working now on changing the getPageSource code to reuse the same code here.
I probably had code following the try/catch, which I later deleted.
It's nice to have the `continue` in there, so if a developer casually added some logic to that iteration, they wouldn't accidentally forget to add it.
