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?
