(require '[clj-http.client :as client]
'[clojure.zip :as z]
'[clojure.data.zip :as dz]
'[clojure.data.zip.xml :as dzx]
'[crouton.html :as html])
(def my-html "<html>\n<body>\n<input src='a.png'/>\n</body>\n</html>")
(def my-zipper (z/xml-zip (html/parse-string my-html)))
(dzx/xml1-> my-zipper)
(dzx/xml1-> my-zipper dz/descendants)
(dzx/xml1-> my-zipper :html)
I am starting with this so that I can understand step-by-step what is
happening here. I built a simple HTML string, converted it into an XML
zipper and then tried a few *xml1 *calls on it:
(dzx/xml1-> my-zipper)
gives me the original zipper, which is what I expected.
(dzx/xml1-> my-zipper dz/descendants)
gives me what appears to be the original zipper structure, which I wasn't
expecting. I was expecting a flattened-out seq of the nodes.
(dzx/xml1-> my-zipper :html)
returns *nil*, which I *really *wasn't expecting. Examples on the web led
me to believe that this last call should match on the html tag. Can anyone
provide any explanation on these call and why I got these return values?
