i am trying to get at all of the elements in enumeration but cant seem to get it right. This is homework so please no full solutions, just guidance if possible.

$feed = simplexml_load_file('http://www.webservicex.net/CurrencyConvertor.asmx?WSDL');

foreach($feed->simpleType as $val){
    $ns s = $val->children('http://www.webserviceX.NET/');
    echo $ns_s -> enumeration;
}

what am i doing wrong?

thanks
