title: PHP / SimpleXML not showing all content
body: <p>I have the following PHP code:</p>
  
  <pre><code>&lt;?php
  $url = 'https://api.datamarket.azure.com/Data.ashx/opendata.rdw/VRTG.Open.Data/v1/KENT_VRTG_O_DAT(\'96TDR3\')';
  $xml = simplexml_load_file($url);
  print_r($xml);
  ?&gt;
  </code></pre>
  
  <p>Output is:</p>
  
  <pre><code>SimpleXMLElement Object
