Pardon the tangent.... Assistive technologies have a need for this (e.g.
a screen reader providing a list of headings for quick navigation). And
we walk the (accessibility) tree. :-/ If you have a need to obtain all
the elements which match a set of criteria, and I have a similar need,
maybe others embedding or interacting with WebKit do too. And if that is
indeed the case, maybe the (long-term) answer is for new WK2 API which
would make this easier for all of us?
