php if else statement not echoing else

I'm trying to echo Norwegian language if there is a xmllang="no" if not echo "noname". Like

000000000121698001,text 000000000121699001,noname

But this is only returning all productids that have a xmllang="no" and not printing productid with no xmllang="no"

XML

<catalog>
<product productid="000000000121698001">
    <displayname xmllang="da">text</displayname>
    <displayname xmllang="fi">text</displayname>
    <displayname xmllang="no">text</displayname>
    <displayname xmllang="sv">text</displayname>    
</product>

<product productid="000000000121699001">
    <displayname xmllang="da">test</displayname>
    <displayname xmllang="x-default">test</displayname>
    <displayname xmllang="sv">test</displayname>
</product>

PHP

foreach ($xml->product as $product) {


foreach ($product->displayname as $name) { 
switch((string) $name['xmllang']) {
case 'no':


  echo $product->attributes()->productid. ",";

  if (isset($name)){
    echo $name. ",", PHP_EOL;
    } else {
    echo 'noname ,';
    }
  echo "<br>\n";
    }
}

}
