NewsManger / xml question

[rigor789]

Hey all!

I customized NewsManager for my needs (added read more function)!
And it works perfect, but i saw the xml writing part and im not sure where the: XMLsave and @getXML comes from!

Code:

if (!file_exists($file)) {
    $date = date('d. m. Y.');
  } else {
    $data = @getXML($file);
    $date = $data->date;
  }

  $xml = @new SimpleXMLElement('<?xml version="1.0" encoding="UTF-8"?><item></item>');
  $xml->addChild('title', $title);
  $xml->addChild('date', $date);
  $xml->addChild('short', $short);
  $xml->addChild('content', $content);
  
  
  XMLsave($xml, $file);

I need to know where that comes from, becasue i need it in one of my projects!
