title: how to get a raw from a DOMNodeList
body: <p>I have a <code>DomDocument</code>, which is impossible to <code>var_dump</code> (it really makes me angry) on which I do : </p>
  
  <pre><code>var_dump($dom-&gt;getElementsByTagName('url'));
  </code></pre>
  
  <p>on a response like this :</p>
  
  <pre><code>&lt;?xml version="1.0" ?&gt;
  &lt;rss version="2.0"&gt;
    &lt;channel&gt;
        &lt;url&gt;beaute-mode/cheveux/11460--choisir-un-headband&lt;/url&gt;
        &lt;title&gt;get_url_article&lt;/title&gt;
        &lt;host&gt;myhost&lt;/host&gt;
    &lt;/channel&gt;
  &lt;/rss&gt; 
  </code></pre>
  
  <p>But I got the <code>var_dump</code> echoing : <code>object(DOMNodeList)[262]</code> instead of my raw data (which is an URL).</p>
  
  <p><strong>So my question is pretty simple but how do I get my raw data without being encapsulated in an <code>DomNodeList</code> ?</strong></p>
  
  <p>thanks.</p>
