php - if no results from xml api call then

I'm running a basic api call and it returns a xml file..i go through the data and set them equal to variables and then echo..all works fine unless there are no results and then it is just blank. How can I add an if statement to check if the api call returned any results?

 if($url_headers[0] == 'HTTP/1.1 200 OK' && (!empty($searchCode))) {
        $xml = simplexml_load_file($searchCode);
foreach ($xml->result->result as $result):
    $cake=$result->{'cakename'};
    $icecream=$result->{'icecreamname'};


   echo "<ul class='cakes' >";
        echo "<li>$cake and $icecream</li>";
    echo "</ul>";
