SYNOPSIS

  use HTML::DOM::Exception 'INVALID_CHARACTER_ERR';

  eval {
          die new HTML::DOM::Exception
                  INVALID_CHARACTER_ERR,

DESCRIPTION

This module implementations the W3C's DOMException and EventException interfaces. HTML::DOM::Exception objects stringify to the message passed to the constructer and numify to the error number (see below, under 'EXPORTS').

METHODS

$errr = new HTML::DOM::Exception $type, $message

This class method creates a new exception object. $type is expected to be an integer (you can use the constants listed under 'EXPORTS'). $message is the error message.

$errr->code

Returns the error code. Same as 0+$errr.

INVALID_CHARACTER_ERR (5)

If an invalid character is specified, such as in a name.

NO_DATA_ALLOWED_ERR (6)

If data is specified for a node which does not support data

NO_MODIFICATION_ALLOWED_ERR (7)
