            <Tutorial>
               <Name>JavaFX</Name>
               <Pages>535</Pages>
               <Author>Krishna</Author>
               <Version>11</Version>
            </Tutorial>";
            $opts = array(
               'http' => array(
                  'user_agent' => 'PHP libxml agent',
               )
            );
            $context = stream_context_create($opts);
            libxml_set_streams_context($context);
          
            $xml = new SimpleXMLElement($str);
            $xml->addAttribute('type', 'test');
            print_r($xml);
         ?>
