A
lso, I saw what you meant that the docs are not quite complete. Perhaps
you would like to add this example to ClojureDocs?
http://clojuredocs.org/clojure_core/clojure.core/re-find
Also, note that it re-seq is aimed to finding a sequence of results within
a single string. For this problem, you really want to process a sequence
of strings (broken up by line) and just filter out the ones you want to
keep. So, re-find seems like the right tool here.
