Unless you're dealing with documents of incredible depth, walking up the tree
should really not be all that costly. What's more, since you're dealing with a
tree that doesn't change, you can walk the tree once and precompute the
language value for every element and cache it so that you only have to walk the
tree once.
But even without that note, have you looked at using
document.querySelectorAll("element:lang(en-us)")? It doesn't do exactly what
you want, but it should provide a decent starting place. If you're using XPath
instead, it has a lang() function that does more or less the same thing.
Oh, and happy birthday!
