Why is my SimpleXML Object Null?

[mtorbin]

Hey all,

 

I'm probably missing something super easy, but for whatever reason, my simpleXML object call is coming back null.  Here is my code:

<?php
class VenueData {
public function __construct($key,$name) {
	$this->searchURL = 'http://ws.audioscrobbler.com/2.0/?method=venue.search&api_key=' . $key . '&limit=1&venue=' . $name;
	$this->searchXML = simplexml_load_file($this->searchURL);
	$this->venueMatches = $this->searchXML->venuematches->{venue};
	print(gettype($this->venueMatches) . "\n");
}
}
?>

 

Without giving away my key, here is a url that you can use to see the xml that's being pulled back:

 

http://ws.audioscrobbler.com/2.0/?method=venue.search&api_key=b25b959554ed76058ac220b7b2e0a026&venue=arena

 

Please help me figure out what I'm missing here.

 

Thanks,

Ah, got it!  I didn't go up high enough on the chain:

<?php
class VenueData {
public function __construct($key,$name) {
	$searchURL = 'http://ws.audioscrobbler.com/2.0/?method=venue.search&api_key=' . $key . '&limit=1&venue=' . $name;
	$searchXML = simplexml_load_file($searchURL);

	foreach($searchXML->results->venuematches->venue as $venue) {
		print($venue->id . "\n");
	}
}
}
?>
