Clojure XML Parsing

Question

I can not find any info on how to parse xml documents and access elements.

I have found two ways to parse the xml document

(clojure.zip/xml-zip (cloj         


        

Answer 1

The above answer works, but I find it a lot easier to use clojure.data.zip.xml (used to be clojure-contrib.zip-filter.xml prior to Clojure 1.3).

file:

myfile.xml:

  Track one
  Track two

code:

; Clojure 1.3
(ns example
  (:use [clojure.data.zip.xml :only (attr text xml->)]) ; dep: see below
  (:require [clojure.xml :as xml]
            [clojure.zip :as zip]))

(def xml (xml/parse "myfile.xml"))
(def zipped (zip/xml-zip xml))
(xml-> zipped :track :name text)       ; ("Track one" "Track two")
(xml-> zipped :track (attr :id))       ; ("t1" "t2")

Unfortunately, you need to pull in a dependency on data.zip to get this nice read/filter functionality. It's worth the dependency :) In lein it would be (as of 17-Aug-2013):

[org.clojure/data.zip "0.1.1"]

And as for docs for data.zip.xml ... I just look at the relatively small source file here to see what is possible. Another good SO answer here, too.
