Answer 1

XPath has a special construct for dealing with xml:lang attribute:

$xml = new SimpleXMLElement($strXML);
$data = $xml->describe->data[0];
$elCode = $data->xpath("code[lang('en')]"); // returns array of SimpleXMLElement
assert(count($elCode)==1);
$code_en = (string) $elCode[0];

P.S. greetings to the Sirena ;)
