What to do with Zend_Rest_Client_Result? - zend-framework

Question

I'm trying to do searches with the API from last.fm with Zend_Rest_Client.
What am I to do with the response? How do I get the values from the response?
object(Zend_Rest_Client_Result)[226]
protected '_sxml' =>
object(SimpleXMLElement)[228]
public '#attributes' =>
array
'status' => string 'ok' (length=2)
public 'results' =>
object(SimpleXMLElement)[229]
public '#attributes' =>
array
...
public 'trackmatches' =>
object(SimpleXMLElement)[230]
...
protected '_errstr' => null
How do I loop over trackmatches? Everything I try returns null.

Answer 1

$results = $object->getIterator();
foreach($result as $result) {
...
}
Above code will do the magic.

Answer 2

You have to keep dereferencing until you get to something that isn't a SimpleXMLElement object. Trying to print a SimpleXMLElement object doesn't work.
$results = $object->getIterator();
foreach($results->results->trackmatches as $t) {
echo $t->sometagname;
}

Answer 3

I did not manage to be able to do it with Zend. Looks like a useless class like Zend_Http. I had to use the gool 'ol SPL:
$url = $this->host . '?method=track.search';
$url .= '&api_key=' . $this->apikey;
$url .= '&track=' . urlencode($value);
try {
$xmlstr = file_get_contents($url);
$xml = new SimpleXMLElement($xmlstr);
//var_dump($xml->results->trackmatches);
return $xml->results->trackmatches;
} catch (Exception $e) {
echo '<h4>url = ' . $url . '</h4>';
var_dump($e);
}
