Yes. And I would further suggest stopping at the first ancestor node
(counting from the target node) with an id attribute, making for an
xpath like //something[@id="something"]/rest/of/path. This generally
improves the quality / longevity of the match, as page structure
changes over time, since it doesn't matter if the beginning of the
page grows additional content, changing the beginning of the xpath
signature of the target node.
