Clojure and enlive are great. In trying to fathom the power of Enlive I'm attempting to apply two transformations to an html page.
The HTML page has 2 areas (divs) that I want to transform. The first div in question gets cloned ~16 times. The second div in question gets cloned 5 times. The original divs (from the html file) should be overwritten or just not appear at all.
Enlive has the idiomatic approach
(apply str (enlive-html/emit* ze-contant-transferm))
this works beautifully well for one transform.
however, I would like to apply two transforms to the page, so I tried something like:
(str
(apply str (enlive-html/emit* ze-first-wan))
(apply str (enlive-html/emit* ze-secand-wan)))
the transformations, done alone, do exactly what I wish: they eat up the original HTML and display the clones that I use for populating with infos.
However, done together in this way, the original html-page divs are preserved, so I end up having the original html file divs along with my clones, and that behavior is no bueno.
Please help.
Thanks-a-much-a.
Enlive-html provides the do-> function for this purpose.
(defn do->
"Chains (composes) several transformations. Applies functions from left to right."
[& fns]
#(reduce (fn [nodes f] (flatmap f nodes)) (as-nodes %) fns))
Which you can use something like this:
(apply str (enlive-html/emit* (enlive-html/do-> ze-first-wan ze-second-wan)))
