come posso estrapolare i vari valori?
ho usato:

$xml = new SimpleXMLElement($data);
echo $xml->methodResponse->params->param->data->member[0]->name 

ma non va...
come posso fare?
thanks

[neorf]

ho provato questa chiamata:

echo $xml->params->param->value->array->data->value->struct->member[1]->value->int; 

funzionare funziona, ma è corretto fare così?
