title: XML tagname is a PHP function
body: <p>I'm trying to parse an XML file in PHP with the <code>simplexml_load_file</code> function. Everything is fine, except my XML file has a <code>&lt;TIME&gt;</code> tag, which is a PHP function.</p>
  
  <p>So the following code fails to get the tag value :</p>
  
  <pre><code>$xml = simplexml_load_file('some_xml_file.xml');
  $value = $xml-&gt;SOME_TAG-&gt;TIME;
  </code></pre>
  
  <p>How do I get this value?</p>
