php - Parse feed media group with array of children -

i have xml feed:

<item>     <title>title</title>     <media:group>         <media:content url="http://example.it/image.jpg" type="image/jpeg">             <media:thumbail url="http://example.it/image.jpg" type="image/png"/>             <media:credit>credit</media:credit>         </media:content>         <media:content url="http://example.it/image2.jpg" type="image/jpeg">             <media:thumbail url="http://example.it/image2.jpg" type="image/png"/>             <media:credit>credit2</media:credit>         </media:content>     </media:group> </item> 

this php code read it:

$rss = new simplexmlelement($url); foreach ($rss->channel->item $item) {     $title = $item->title; } 

no problem reading "title" item, how can read "url", "thumbnail", "credit" each media:content?

-------solved-------

$rss = new simplexmlelement($url); foreach ($rss->channel->item $item) {     $title = $item->title;     $gallerie = $item->children('http://search.yahoo.com/mrss/')->group->content;     foreach($gallerie $g) {         echo $g->attributes()['url'] ."<br/>";     } }
