Does inserting clojure.zip/down between the two :thing's help?
If these examples are representative, then clojure.core/xml-seq could be
simpler than zippers:
(def xmlstuff (first example1)) ;; you got a list from parse; get the root
element
(->> xmlstuff xml-seq (filter #(= :thing (:tag %))) (mapcat :content)
(filter string?))
;; ("Want this" "Select this")
Other techniques to consider:
- If capable selectors are important, consider Enlive. It, too, starts
with what you get from clojure.xml/parse, and it, too, uses zippers inside.
- If you like zippers, with a plain old loop you may use clojure.zip/next
to traverse the tree and harvest the text nodes you need. You could even
look only at text nodes, and query the zipper for their parent...
- If you like zippers and xml->, the functions you can use in an xml-> path
are not a closed set -- you may make a function that does what you want.
