How to get image element on XML document with PHP? -


i'm trying thumbnail links like:

https://i.pinimg.com/236x/38/8f/c9/388fc91621d9d12db3d1211b39ab0fc1--flying-dog-pure-joy.jpg

but reason getelementsbytagname doesn't return wanted.

$newdom=new domdocument(); $xml=simplexml_load_file("https://www.pinterest.co.uk/sucastro/animals.rss"); $newdom->loadxml($xml); $out=$newdom->getelementsbytagname('img'); print_r($out);

i tried

$out=$newdom->channel->item->description->getelementsbytagname('img');

which failed.

simplexmlelement object (     [@attributes] => array         (             [version] => 2.0         )      [channel] => simplexmlelement object         (             [title] => animals             [link] => https://www.pinterest.com/sucastro/animals/             [description] => simplexmlelement object                 (                 )              [language] => en-us             [lastbuilddate] => fri, 48 jan 2017 33:33:33 +0000             [item] => array                 (                     [0] => simplexmlelement object                         (                             [title] => hi ladies. let's pin                             [link] => https://www.pinterest.com/pin/209628557639623067/                             [description] => <a href="/pin/209628557639623067/"><img src="https://i.pinimg.com/236x/38/8f/c9/388fc91621d9d12db3d1211b39ab0fc1--flying-dog-pure-joy.jpg"></a>hi ladies. let&#39;s pin green , white today ❤️                             [pubdate] => fri, 08 sep 2017 20:04:02 +0000                             [guid] => https://www.pinterest.com/pin/209628557639623067/                         )

i have looked around hours trying different things, reason still doesn't work.

this fetches images descriptions of rss channels.

you can try : 

<?php  $xml=simplexml_load_file("https://www.pinterest.co.uk/sucastro/animals.rss"); foreach ($xml->channel->item $item) {     preg_match('/<img.+src=[\'"](?p<src>.+?)[\'"].*>/i', $item->description, $image);     echo($image['src']);     echo "<br/>"; }  ?>

output :
