I'm not totally sure about XPath APIs in Java, but XPath is just the ticket
for this sort of thing. Something like:
//a[ends-with(@href, 'rpm')]
Much like I don't do complicated text processing without regexes (or
perhaps a parser), I wouldn't do complicated DOM stuff without at least
considering XPath.
