For the life of me I cant figure out how to do this simple thing, new to dealing with xml in php.

I am getting an xml from the discogs api and would like to filter my results by the attribute "type" found in the release part of the xml snippet below.

The xml has types "main" "remix" etc in it for the release field. I would like to build loop the array with ONLY the releases that are of type "main". The php pertinent to the release array is below in the code area.

I am trying all i can with stuff like $type = $rel->item(0)->getAttribute("type"); and then an if in the loop, but it's failing. arg.

Thank you for any assistance!
// the structure of the xml I am getting
 
<resp stat="ok" version="1.0" requests="1"> 
  <artist>
    <releases>
      <release id="63114" status="Accepted" type="Main">
        <title></title>  
        <format></format>  
        <label></label>  
        <year></year>
       <release id="63114" status="Accepted" type="Remix">
        <title></title>  
        <format></format>  
        <label></label>  
        <year></year>    
      </release>  
     </releases>  
   </artist>  
</resp>  
 
// the php I am using to build an array, I want only releases with type "main"
 
$doc = new DOMDocument('1.0', 'UTF-8');
$doc->loadXML($response);
$rel = $doc->getElementsByTagName("release");
 
foreach ($rel as $release)
{
    $title = $release->getElementsByTagName("title")->item(0)->nodeValue;
    $format = $release->getElementsByTagName("format")->item(0)->nodeValue;
    $label = $release->getElementsByTagName("label")->item(0)->nodeValue;
    $year = $release->getElementsByTagName("year")->item(0)->nodeValue;
    
    $releases[$title] = array ("title" => $title,
                           "format" => $format,
                           "label" => $label,
                           "year" => $year,
                             );
}
