Getting media:thumbnail from RSS using simplexml_load_file

Question

I want to get media:thumbnail url from this RSS. It's a wordpress blog:

http://blog.khayyamkar.ir/category/news/feed/

I did some research and found this solution:

https://www.sitepoint.com/parsing-xml-with-simplexml/

But thumbnail attribute is always NULL! and I cannot find the problem

UPDATE: -> 'group' was a miss understanding.

the new code is this. But it's a "object(SimpleXMLElement)[33]" and I don't know how to extract Url:

$item->children($namespace['media'])

This is my code:

$url = $this->config->config['wp_news_feed'];
$xml = simplexml_load_file($url, null, LIBXML_NOCDATA);
$namespace = $xml->getNamespaces(true);

foreach ($xml->channel->item as $item)
{    
    // $group = $item->children($namespace['media'])->group;
       $group = $item->children($namespace['media']);
    var_dump($group->thumbnail);// <------ This is object(SimpleXMLElement)[32]
}

See php.net/manual/en/simplexml.examples-basic.php#example-6432 how to access attributes. — Dormilich

Because there is no <group> element in the first item. To be more precise, there is not even the string 'group' contained anywhere in the XML!

Also 'thumbnail' is an element, not an attribute.
