Hello Mike,
Take a look at hickory, it's more straightforward than enlive if you want
to find something in html: https://github.com/davidsantiago/hickory
(ns ......
(:require [hickory.core :as h]
[hickory.select :as hs]
[cljs.core.async :as a]))
let [html (:body (a/<! (http/get url)))
parsed (-> html h/parse h/as-hickory)
inputs (hs/select
(hs/and
(hs/tag :input)
(hs/attr :href #(re-find #"sop://" %)))
parsed)]
Best regards,
Eduard
