当存在双xml标记时从xml soap响应中获取元素值

Question

I HAVE THIS XML RESPONSE FROM A SOAP CALL:

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><loginResponse xmlns="http://wws.adomain.com/"><loginResult><xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"><xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:MainDataTable="replay" msdata:UseCurrentLocale="true"><xs:complexType><xs:choice minOccurs="0" maxOccurs="unbounded"><xs:element name="replay"><xs:complexType><xs:sequence><xs:element name="code" type="xs:string" minOccurs="0" /><xs:element name="description" type="xs:string" minOccurs="0" /></xs:sequence></xs:complexType></xs:element></xs:choice></xs:complexType></xs:element></xs:schema><diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1"><DocumentElement xmlns=""><replay diffgr:id="replay1" msdata:rowOrder="0" diffgr:hasChanges="inserted"><code>OK</code><description>

I want to be able to get the values of element (eg token) in the second xml tag (<?xml version="1.0" encoding="UTF-8"?>) Any prompt assistance will be appreciated.

HERE IS MY CODE:

$s = new soapclientw($wsdlfile);
if (empty($proxyhost))
{

}
else{
    $s->setHTTPProxy($proxyhost,$proxyport,$proxyusr,$proxypassword);
}
$result = $s->send($msg,'http://wws.domain.com/login',60);

$myXMLData = $s->responseData;

libxml_use_internal_errors(true);

$xml = simplexml_load_string($myXMLData);

if ($xml === false) {
    echo "Failed loading XML: ";
    foreach(libxml_get_errors() as $error) {
        echo "<br>", $error->message;
    }
} 
else{
    echo $xml->token;
}

Given your original, highly dubious xml, the following is a bit of a hack but it works..

    $strxml='
