Just learned about the W3C Selectors API from Simon's blog. Turns out a native implementation is forthcoming in Firefox 3.1 (as well as Opera, IE 8, and WebKit), but in the meantime many Javascript libraries already implement the spec, Mootools, jQuery, and Prototype to name a few.
WebKit provides a speed test of a native implementation of querySelectorAll vs popular Javascript libraries (obviously the native implementation won't work for you unless you're using a Firefox beta). It's based on Mootools' test.
