4. Look for any strings that look like a DOI:

	\b((?:http://dx.doi.org/|doi:|)10.[\d.]+/(?:\S+))

(as it sucks to code special things for each database, in case they change or you add a new one)

You can then fall back to #1 if necessary.

I’ve long had jQuery on my “I guess I’m going to have to learn this someday but, um, today I just wanna stick with what I know” list. So is this the kind of thing where it’s going to be quicker to learn something about jQuery before I get started, or can I just as easily muddle along with my existing limited Javascript? (What really are the pros and cons here?)

If depends on what you're going to do with the output -- I'd likely look through the <a href=''> values for http://dx.doi.org DOIs first, then just look at the text displaying on the page.  I don't think you'd need jQuery for that.
