Xml Soap parsing (wsdl)

[ricman]

Mi date una mano a prelevare i singoli dati (in php 5..) da un xml del genere?

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
	<GetHistoricalSpotPriceRangeResponse xmlns="http://www.xignite.com/services/">
		<GetHistoricalSpotPriceRangeResult>
			<Outcome>RegistrationError</Outcome>
			<Message>
				XigniteMetals: Maximum number of unregistered requests exceeded...
			</Message>
			<Identity>IP</Identity>
			<Delay>0</Delay>
			<Type>ARE</Type>
			<Currency>USD</Currency>
		</GetHistoricalSpotPriceRangeResult>
	</GetHistoricalSpotPriceRangeResponse>
</soap:Body>
</soap:Envelope>

Questo file lo ottengo dinamicamente dal sito Xignite (quotazioni/statistiche varie) tramite uno scrpt in php (ma le info che trovo sono scarse...)
Allego qui sotto il codice d'esempio che ho trovato...

// define the SOAP client using the url for the service
$client = new soapclient('http://www.xignite.com/xMetals.asmx?WSDL', array('trace' => 1));

// create an array of parameters 
$param = array(
               'Type' => "XAU",
               'Currency' => "USD",
               'StartDate' => "11/6/2010",
               'EndDate' => "12/5/2010");



// call the service, passing the parameters and the name of the operation 
$result = $client->GetHistoricalSpotPriceRange($param);
// assess the results 
if (is_soap_fault($result)) {
     echo '<h2>Fault</h2><pre>';
     print_r($result);
     echo '</pre>';
} else {
     echo '<h2>Result</h2><pre>';
     print_r($result);
     echo '</pre>';
}
// print the SOAP request 
echo '<h2>Request</h2><pre>' . htmlspecialchars($client->__getLastRequest(), ENT_QUOTES) . '</pre>';
// print the SOAP request Headers 
echo '<h2>Request Headers</h2><pre>' . htmlspecialchars($client->__getLastRequestHeaders(), ENT_QUOTES) . '</pre>';
// print the SOAP response 
$xmlString= '<h2>Response</h2><pre>' . htmlspecialchars($client->__getLastResponse(), ENT_QUOTES) . '</pre>';
