util.xtemplate: Test the each template function It iterates over childtags, so a template like {foo|each{...}} would be equivalent to root:childtags("foo"), while a deeper query needs the bit that becomes arguments to :childtags as an argument to each, e.g. {foo/bar|each(baz)} would behave like root:get_child("foo"):get_child("bar"):childtags("baz")
