Hi Base,
Perhaps something like the following:
(defn normalize-creatures [creatures]
(letfn [(split [str] (seq (.split str "\\s")))]
(for [{:keys [animal sound number-of-feet]} creatures]
(map (fn [a s n]
{:animal a :sound s :number-of-feet n})
(split animal) (split sound) (split number-of-feet)))))
;; *foo* is the test data you mentioned
(normalize-creatures *foo*)
=> (({:animal "dog" :sound "woof" :number-of-feet "4"}
{:animal "cat" :sound "meow" :number-of-feet "4"}
{:animal "bird" :sound "chirp" :number-of-feet "2"})
({:animal "horse" :sound "neeeee" :number-of-feet "4"})
({:animal "wolf" :sound "howl" :number-of-feet "4"}
{:animal "pig" :sound "oink" :number-of-feet "4"}))
All the best,
Tayssir
