Question

I’m trying to write a script that grabs the URL of the first image from this website: http://www.slothradio.com/covers/?adv=&artist=pantera&album=vulgar+display+of+power

Here’s my script:

$content = file_get_contents($url);
$doc = new DOMDocument();
$doc->loadHTML($content);
$xpath = new DOMXpath($doc);

$elements = $xpath->query("*/div[@class='album0']/img");
echo '<pre>';print_r($elements);exit;

When I run that, it outputs

DOMNodeList Object
(
)

Even when I change my query to $xpath->query("*/img"), I still get nothing. What am I doing wrong?

Answer 1

$doc->loadHTMLFile($content); takes in FILE PATH not HTML content see documentation

http://php.net/manual/en/domdocument.loadhtmlfile.php

Use

$doc = new DOMDocument();
$doc->loadHTMLFile($url);

To Output Element use

var_dump(iterator_to_array($elements)); 
//Or
print_r(iterator_to_array($elements));

Thanks
