Quick & dirty technique:
(ns tst.demo.core
(:use demo.core tupelo.core tupelo.test)
(:require
[clojure.java.io :as io]
[clojure.walk :as walk]
[tupelo.parse.tagsoup :as tagsoup] ))
(dotest
(let [txt (slurp (io/resource "test.html"))
>> (println txt)
enlive-data (tagsoup/parse txt)
>> (spyx-pretty enlive-data)
found-comment? (atom false)
tx-fn (fn [item]
(when (and (map? item)
(= :comment (:type item))
(= "more" (:data item)))
(reset! found-comment? true))
(if @found-comment?
nil
item))
enlive-keep (walk/prewalk tx-fn enlive-data) ]
(newline)
(spyx-pretty enlive-keep)
) )
with result:
