Well, we could work harder on that regular expression and correct the problem, but yeah, your CSS trick works a lot better.

FWIW, in my replacement for getElementsByClassName I simply look for the given string to be contained in the className. Yes, I know that means that looking for "one" will incorrectly find "one-active" or even "none" or "lonesome". But that just means I'm really careful about making sure my class names don't have potential problems like that.
