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'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

You need to use getAttribute() instead of attributes property

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

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>";

}

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>";

}
