Get the URL tag from enclosure XML

Question

I want to get the URL from the enclosure tag with PHP

This is what i get from the RRS feed

<item>
    <title>Kettingbotsing met auto&#039;s en vrachtwagen op A2</title>
    <link>https://www.1limburg.nl/kettingbotsing-met-autos-en-vrachtwagen-op-a2</link>
    <description>&lt;p&gt;Drie auto&amp;#39;s en een vrachtauto zijn woensdagochtend met elkaar gebotst op de A2.&amp;nbsp;&amp;nbsp;&lt;/p&gt;</description>
    <pubDate>Wed, 21 Nov 2018 07:37:56 +0100</pubDate>
    <guid permalink="true">https://www.1limburg.nl/kettingbotsing-met-autos-en-vrachtwagen-op-a2</guid>
    <enclosure type="image/jpeg" url="https://www.1limburg.nl/sites/default/files/public/styles/api_preview/public/image_16_13.jpg?itok=qWaZAJ8v" />
 </item>

This is the code im using now

$xmlDoc = new DOMDocument();
$xmlDoc->loadXML($xml_string);

foreach ($xmlDoc->getElementsByTagName('item') as $node) {
    $item = array(
        'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
        'img' => $node->getElementsByTagName('enclosure')->item(0)->attributes['url']->nodeValue
    );
    echo "<pre>";
    var_dump($item);
    echo "</pre>";
}

And this is the result

array(2) {
    ["title"]=>
    string(46) "Kettingbotsing met auto's en vrachtwagen op A2"
    ["img"]=>
    string(10) "image/jpeg"
}

I'm currently getting the type of the enclosure tag, but i'm searching for the url.

Can someone help me, Thanks in advance

As an alternative to using DOMDocument, it's much clearer (IMHO) to use SimpleXML in this sort of case. The code ends up as...

$doc = simplexml_load_string($xml_string);
foreach ($doc->item as $node) {
    $item = array(
        'title' => (string)$node->title,
        'img' => (string)$node->enclosure['url']
    );
    echo "<pre>";
    var_dump($item);
    echo "</pre>";
}

You need to use getAttribute() instead of attributes property

$node->getElementsByTagName('enclosure')->item(0)->getAttribute('url')

DOM supports Xpath expressions to fetch node lists and single values from an XML.

$document = new DOMDocument();
$document->loadXML($xml_string);
$xpath = new DOMXpath($document);

// iterate any item node in the document
foreach ($xpath->evaluate('//item') as $itemNode) {
    $item = [
        // first title child node cast to string
        'title' => $xpath->evaluate('string(title)', $itemNode),
        // first url attribute of an enclosure child node cast to string
        'img' => $xpath->evaluate('string(enclosure/@url)', $itemNode)
    ];
    echo "<pre>";
    var_dump($item);
    echo "</pre>";
}

something simple like

$node->enclosure['url']

should work i guess? At least with simplexml https://www.php.net/manual/en/book.simplexml.php
