// File opening in read mode
$file_pointer = fopen($xml_file, 'r');
// Reading data from the file stream

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) .
"<br/>Line: " .
// Line number where the error occurred
