    echo $item->xpath('media:thumbnail',1)->url.'<br />';
    echo $item->xpath('bc:duration').'<br />';
    echo '<hr />';
}
?>

How to parse some node like media:player,media:thumbnail, bc:duration? I met some wrong, 2 string array and 2 wrong...

Array

Heh, for some reason, a _lot_ of people can't seem to do it ;) To be fair, knowing it is called a 'namespace' does help a lot... — Wrikken, Jan 31 '12 at 20:17

This gets you, what you want:

$hlp = $item->xpath('media:thumbnail[1]');
echo $hlp[0]['url'];

Maybe, there are better methods...I'll see, if I can find some.

Regarding the errormessage, ThinkingMonkey is right - you used the function incorrectly.

edit: This is probably a faster and more beautiful solution:

$media = $item->children('http://search.yahoo.com/mrss/');
$hlp = $media->player->attributes();
echo $hlp['url'].'<br />';
$hlp = $media->thumbnail[0]->attributes();
echo $hlp['url'].'<br />';
$hlp = $media->thumbnail[1]->attributes();
echo $hlp['url'].'<br />';

Most part of your code looks fine except for the use of function xpath()

From SimpleXMLElement::xpath ^manual

public array SimpleXMLElement::xpath ( string $path )

It accepts only one parameter! you are passing 2 params:

echo $item->xpath('media:thumbnail',0)->url.'<br />';
echo $item->xpath('media:thumbnail',1)->url.'<br />';

You have used it correctly here!

echo $item->xpath('media:player').'<br />';

Just do this to access your media:thumbnail. Since, they will be parsed & stored as array:

echo $item->xpath('media:thumbnail[0]')->url.'<br />';
echo $item->xpath('media:thumbnail[1]')->url.'<br />';
