Can't gzdecode on base64decode from soap response - php

Question

I got a problem with this SOAP response :
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetStockResponse xmlns="http://retailexpress.com.au/">
<GetStockResult>base64Binary</GetStockResult>
</GetStockResponse>
</soap:Body>
</soap:Envelope>
So, my code for handle this response look like this :
public function getStock()
{
$soapClient = $this->getSoapClient();
$xmlRequest = soapHead . '<ret:GetStock></ret:GetStock>' . soapFoot;
try {
$request = $soapClient->__anotherRequest('GetStock', $xmlRequest);
$requestDecoded = base64_decode($request);
$stock = gzdecode($requestDecoded);
} catch (SoapFault $e ){
var_dump($e);
exit();
}
$response = new Response($stock);
$response->headers->set('Content-Type', 'text/xml');
return $response;
}
With this code I always got this error :
Warning: gzdecode(): data error
But if I var_dump $request decoded and I try to gzdecode this string it works !
I can't find my mistake here ...
And for each try I got to wait 5 minutes ^^'
I hope I'm enough understandable
Thanks by advance

I find the solution,
The soap response is an xml so you need to create a SimpleXmlElement to get the content
$request = $soapClient->__anotherRequest('GetStock', $xmlRequest);
$xmlRequest = new \SimpleXMLElement($request);
$response = $xmlRequest->children('http://schemas.xmlsoap.org/soap/envelope/')->Body->children()->GetStockResponse;
$result = (string) $response->GetStockResult;
$requestDecoded = base64_decode($result);
$stock = gzdecode($requestDecoded);
