I have the following structure:

<div class="xGh" style="background-image: url('name_file.jpg');"></div>

Where I need to capture:

name_file.jpg

I tried to use the solution presented in this reply, but it is not working, it presents a syntax error:

See the test with the error in Ideone

$img = $xpath->query(substring-before(substring-after(//div[@class='xGh']/@style, "background-image: url('"), "')"));    

echo $img->item($i)->nodeValue."<br/>";

I know how to do with regex, but wanted to use xpath, it is possible?

Yes, it is possible. The code path is correct, it is only necessary to fix the syntax and xpath.

<?php
$dom = new DOMDocument;
$dom->loadHTML('<div class="xGh" style="background-image: url(\'name_file.jpg\');"></div>');

$xpath = new DOMXpath($dom);
$xpatyQ = "substring-before(substring-after(//*[@class=\"xGh\"]/@style, \"background-image: url('\"), \"')\")";
$img = $xpath->query($xpatyQ);

$result = $xpath->evaluate($xpatyQ);
echo $result; // name_file.jpg
