Note that textContent property of a comment is not entity decoded, it is decoded in DOMElement::textContent :



<?php 



   $xml = new DOMDocument();

    $xml->loadXML('<?xml version="1.0" encoding="utf-8"?>

      <configuration version="2">

      <!-- test &#45;&#45;&gt; -->

      test &#45;&#45;&gt;

      </configuration>'

    );

$xpath = new DOMXPath($xml);

$comments = $xpath->query('//comment()');

$elements = $xpath->query('//configuration');



echo $comments[0]->textContent;

// result: test &#45;&#45;&gt;



echo $elements[0]->textContent;

// result: test -->



?>
