A simple translation to condp:
(defn parse-group [group-identifier line]
(condp = group-identifier
"ID1" (handle-id1 line)
"ID2" (handle-id2 line)
"ID3" (handle-id3 line)))
But you may want something more extensible:
(def group-handlers
{"ID1" handle-id1,
"ID2" handle-id2,
"ID3" handle-id3})
(defn parse-group [group-identifier line]
(if-let [handler (group-handlers group-identifier)]
(handler line)
(println "unknown group identifier")))
A multimethod might also be an appropriate way forward for you.
