Hi.
Using at and content, I can replace the content of whatever I've
selected with nothing.
For example:
(require '[net.cgrand.enlive-html :as html])
(-> "<html><head><title>asdf</title><body><div id='derp'><a href='#'>I
am a link.</a></div><div id='anotherLink'>moar content</div></body</
html>"
java.io.StringReader.
html/html-resource
(html/at #{[:#derp]} (html/content "")))
Now, div#derp contains nothing instead of the link.
My question is: What if I want to delete div#derp altogether from the
DOM?
Thank you for your time.

Instead of content, use a fn whose return value is nil.

If you *always* need to remove that div, you can also use nil directly.
user> (-> "<html><head><title>asdf</title></head><body><div id='derp'><a href='#'>I am a link.</a></div></body</html>"
java.io.StringReader.
html/html-resource
;; either (html/at #{[:#derp]} (fn [& args] (when (derp-day) identity)))
;; or
(html/at #{[:#derp]} nil))
=>
({:tag :html, :attrs nil, :content ({:tag :head, :attrs nil, :content ({:tag :title, :attrs nil, :content ("asdf")})} {:tag :body, :attrs nil, :content ({:tag :div, :attrs {:id "anotherLink"}, :content ("moar content")})})})
