Reading XML data into Incanter datasets
One of the most popular formats for data is XML. Some people love it, while some hate it.
However, almost everyone has to deal with it at some point. While Clojure can use Java's
XML libraries, it also has its own package which provides a more natural way to work with
XML in Clojure.
Getting ready
First, include these dependencies in your Leiningen project.clj ile:
(defproject getting-data "0.1.0-SNAPSHOT"
:dependencies [[org.clojure/clojure "1.6.0"]
[incanter "1.5.5"]])
Use these libraries in your REPL or program:
(require '[incanter.core :as i]
'[clojure.xml :as xml]
'[clojure.zip :as zip])
Then, ind a data ile. I visited the website for the Open Data Catalog for Washington, D.C.
( http://data.octo.dc.gov/ ) , and downloaded the data for the 2013 crime incidents.
I moved this ile to data/crime_incidents_2013_plain.xml . This is how the contents
of the ile look:
<?xml version="1.0" encoding="iso-8859-1"?>
<dcst:ReportedCrimes
xmlns:dcst="http://dc.gov/dcstat/types/1.0/">
