title: Parsing XML using PHP
body: <p>I've consistently had an issue with parsing XML with PHP and not really found "the right way" or at least a standardised way of parsing XML files.</p>
  
  <p>Firstly i'm trying to parse this:</p>
  
  <pre><code>  &lt;item&gt; 
       &lt;title&gt;2884400&lt;/title&gt; 
       &lt;description&gt;&lt;![CDATA[ &gt;&lt;img width="126" alt="" src="http://userserve-ak.last.fm/serve/126/27319921.jpg" /&gt; ]]&gt;&lt;/description&gt; 
       &lt;link&gt;http://www.last.fm/music/+noredirect/Beatles/+images/27319921&lt;/link&gt; 
       &lt;author&gt;anne710&lt;/author&gt; 
       &lt;pubDate&gt;Tue, 21 Apr 2009 16:12:31 +0000&lt;/pubDate&gt; 
       &lt;guid&gt;http://www.last.fm/music/+noredirect/Beatles/+images/27319921&lt;/guid&gt; 
       &lt;media:content url="http://userserve-ak.last.fm/serve/_/27319921/Beatles+2884400.jpg" fileSize="13065" type="image/jpeg" expression="full"  width="126" height="126" /&gt; 
       &lt;media:thumbnail url="http://userserve-ak.last.fm/serve/126/27319921.jpg" type="image/jpeg" width="126" height="126" /&gt; 
    &lt;/item&gt; 
  </code></pre>
  
  <p>I'm using this code:</p>
  
  <pre><code>$doc = new DOMDocument();
  $doc-&gt;load('http://ws.audioscrobbler.com/2.0/artist/beatles/images.rss');
  $arrFeeds = array();
  foreach ($doc-&gt;getElementsByTagName('item') as $node) {
      $itemRSS = array ( 
          'title' =&gt; $node-&gt;getElementsByTagName('title')-&gt;item(0)-&gt;nodeValue,
          'desc' =&gt; $node-&gt;getElementsByTagName('description')-&gt;item(0)-&gt;nodeValue,
          'link' =&gt; $node-&gt;getElementsByTagName('link')-&gt;item(0)-&gt;nodeValue,
          'date' =&gt; $node-&gt;getElementsByTagName('pubDate')-&gt;item(0)-&gt;nodeValue
          );
      array_push($arrFeeds, $itemRSS);
  }
  </code></pre>
  
  <p>Now I want to get the "media:content" and "media:thumbnail" url attributes, how would i do that? Now i think i should be using DOMElement::getAttribute but i haven't managed to get it to work :/ Can anyone shed some light on this, and also let me know if this is a good way to parse XML?</p>
