// File opening in read mode
$file_pointer = fopen($xml_file, 'r');
  
// Reading data from the file stream
while ($xml_data = fread($file_pointer, 4096)) {
     
    // Parse the data chunk
    if(!xml_parse($xml_parser, $xml_data,
                        feof($file_pointer))) {
         
        // Displaying errors
        die( print "ERROR: " . 
         
            // Error string
            xml_error_string(xml_get_error_code($xml_parser)) . 
             
            "<br/>Error Code: " . 
             
            // Error code
            xml_get_error_code($xml_parser) .
