seems so :-)

XMLReader is more powerful and can read/parse files. The big advantage 
is the possibility to read streams for very fast parsing of big files.

Have a look here:
http://php.net/en/xmlreader

Example:
$xml = XMLReader::open($this->content);
$xml->setParserProperty(XMLReader::VALIDATE, true);
if ($xml->isValid()) {...}
