I'm not that familiar with Enlive, so I can't comment on the ease of that
approach.
However, the way I'd personally do it is that I'd make use of Crouton and
the zipper functions in clojure.zip and clojure.data.zip. A zipper is a
functional way of navigating an immutable data structure.
So first add Crouton and data.zip to your dependencies:
[[crouton "0.1.2"]
[org.clojure/data.zip "0.1.1"]]
Then use Crouton to parse the body of the response from clj-http:
(crouton.html/parse (:body response))
This will give you a data structure that's compatible with clojure.xml, and
therefore compatible with the XML zipper functions
(dzx/xml1-> (z/xml-zip parsed-html)
dz/descendents
(dzx/tag= "input")
(dzx/attr= "name" "foo")
In the above case I'm using the following namespace aliases:
(require '[clojure.zip :as z]
'[clojure.data.zip :as dz]
'[clojure.data.zip.xml :as dzx])
It's been a while since I've needed to traverse X/HTML in Clojure though,
so my code might be a little off.
