I did a bit of performance testing on this just for fun; Native vs.
prototype.js's xpath version vs. prototype.js's DOM traversal version

native: 303ms
xpath: 5,706ms
js/dom: 26,660ms

:)

I also tried out aroben's second suggestion, but it seemed like a bit of a
wash. Made the getElementsByClassName callsite a little nicer, and the
NamedMappedAttrMap one a little less nice. What about making a regular
constructor that takes a class attribute string and calls through to
parseClassAttribute? Is that sort of minor convenience method generally
considered worthwhile in webkit?
