SAX is meant to use exceptions as much as possible to flag problems.=head1 CREATING NEW EXCEPTION CLASSESAll you need to do to create a new exception class is: @XML::SAX::Exception::MyException::ISA = ('XML::SAX::Exception')The given package doesn't need to exist, it'll behave correctly this way. If your exception refines an existing exception class, then youmay also inherit from that instead of from the base class.=head1 THROWING EXCEPTIONSThis is as simple as exemplified in the SYNOPSIS. In fact, there's nothing more to know. All you have to do is: throw XML::SAX::Exception::MyException( Message => 'Something went wrong' );and voila, you've thrown an exception which can be caught in an eval block.=cut
