non-object and invalid argument

Hi,

I have a problem with reading an xml file... and am not sure why I'm getting the error.
So here is a part of the xml:

<status>
<shard name="Blightweald" online="True" locked="False" population="high" queued="0" language="English" pvp="False" rp="False" recommend="False"/>
<shard name="Cloudborne" online="True" locked="False" population="high" queued="0" language="English" pvp="True" rp="False" recommend="False"/>
<shard name="Steampike" online="True" locked="False" population="high" queued="0" language="English" pvp="False" rp="False" recommend="False"/>
</status>

Select allOpen in new window

and here is my code:

$url = "http://eu.riftgame.com/en/status/eu-status.xml";

		// READ THE EXTERNAL DATA
		$xml = simplexml_load_file($url);

		foreach ($xml->status["shard"] as $shard)
		{
			if ($shard["name"] == "Blightweald")
			{
				echo $shard->name;
				echo $shard->population;
			}
		}

Select allOpen in new window

I even tried setting
$xml->status["shard"]

to

$xml->status->shard

But no use. That would be an invalid argument.

Any ideas?
