FWIW I found a solution by mimicking the original tag=:
With data.zip as dz and clojure.zip as zip the following predicate can be
used inside of xml->
(defn tag-is-one-of [tagnames]
(fn [loc]
(filter
(fn [l]
(and (zip/branch? l)
(some #(= % (:tag (zip/node l))) tagnames)))
(if (dz/auto? loc)
(dz/children-auto loc)
(list (dz/auto true loc))))))
(clojure.data.zip.xml/xml-> x :a (tag-is-one-of [:b1 :b3]) :c)
(Now I only need to read about all those auto-functions.)
Regards,
stefan
