Not sure right away, but perhaps it might give you some inspiration

Thanks, I'll take a look 🙂

I think you could combine it at least to move to the map with the right id and then remove or replace it using a zipper operation

In case anyone is interested, this is the closest I came up with...

(defn filterz [zloc f] (z/find zloc #(->> % z/string f)))

  (defn replace-entry [content id new-content]
    (-> (z/of-string content)
        z/down
        (filterz #(= (:id (clojure.edn/read-string %)) id))
        (z/replace new-content)
        z/root-string))

z/sexpr may be useful to you in the future, rather than comparing strings.

z/sexpr may blow up in your face sometimes though ;)

I'll look it up, thanks
