Interesting, I find the documention of dom-elements confusing:

what are the "elements" then? attributes not tags/ dom entries? But yes
that would be a bugreport about the documentation also that dom-elements
is not even listed in the gnu doku seem strange to me.
But maybe I am just not good enough in xml lingo.
Could you explain a bit or show a example of the dom-search function or
explain it's parameters. I have no idea what in the docstring
"predicate" means and in what format it's expected, is Predicate a known
term for something specific?
