Hi Linus, Zippers and their associated helpers are woefully undocumented, so I'm not surprised you fell into the swamp.
I think that the help you're looking for can be found in the clojure.data contrib project (see https://github.com/clojure/data.zip for the source and http://clojure.github.com/data.zip for the autodoc). Using that, the xpathy thing you're looking for is something like this: (ns play.xml-example (:require [clojure.zip :as zip] [clojure.data.zip :as zf] [clojure.xml :as xml]) (:use clojure.data.zip.xml)) (def mz (zip/xml-zip (xml/parse "dataabove.xml"))) (defn get-all-dimensions [] (doseq [id (xml-> mz zf/descendants (attr= :id "2") zf/children :e (attr :id))] (println (apply str id)))) Note that I had to make a couple of fixes to the above XML to make it right. I hope that's useful!
