PHP DOM get nodevalue html? (without stripping tags)

I am trying to get the innerhtml of div tags in a file using nodeValue, however this code is outputting only plain text and seems to strip out all html tag from inside the div. How can I change this code to output the div's HTML content and not plain text, AND also output the main div wrapping it's child elements.

Example:

contents of file.txt:

<div class="1"><span class="test">text text text</span></div>
<div class="2"><span class="test">text text text</span></div>
<div class="3"><span class="test">text text text</span></div>


script.php:

$file= file_get_contents('file.txt');

$doc = new DOMDocument();

@$doc->loadHTML('<?xml encoding="UTF-8">'.$file);

$entries = $doc->getElementsByTagName('div');

for ($i=0;$i<$entries->length;$i++) {
$entry = $entries->item($i);
echo $entry->nodeValue;
}


outputs: text text texttext text texttext text text

what I need it to output:

<div class="1"><span class="test">text text text</span></div>
<div class="2"><span class="test">text text text</span></div>
<div class="3"><span class="test">text text text</span></div>


Notice the parent div's (..etc) are needed to be outputted as well wrapping the span tags...

HELP!

Answer

I have never done what you're attempting to do, but as a stab in the dark, using the API docs, does echo $entry->textContent; work?

Adding an update. This is from the comments located on the docs page for DOMNode:

Hi!

Combining all th comments, the easiest way to get inner HTML of the node is to use this function:

<?php  function get_inner_html( $node ) { 
    $innerHTML= ''; 
    $children = $node->childNodes; 
    foreach ($children as $child) { 
        $innerHTML .= $child->ownerDocument->saveXML( $child ); 
    } 

    return $innerHTML;  }  ?>

Or, maybe a simpler method is just to do:

echo $domDocument->saveXML($entry);
