title: How do I parse XML using Nokogiri and split a node value?
body: <p>I'm using Nokogiri to parse XML.</p>
  
  <pre><code>doc = Nokogiri::XML("http://www.enhancetv.com.au/tvguide/rss/melbournerss.php")
  </code></pre>
  
  <p>I wasn't sure how to actually retrieve node values correctly.</p>
  
  <p>I'm after the <code>title</code>, <code>link</code>, and <code>description</code> nodes in particular that sit under the <code>item</code> parent nodes.</p>

  <p>What I'd like to do is <code>title.split("-")</code> in such a way that I can convert the date and time strings into a valid <code>DateTime</code> object to use later on down the track.</p>
