If your exception refines an existing exception class, then you may also inherit from that instead of from the base class. .SH "THROWING EXCEPTIONS" .IX Header "THROWING EXCEPTIONS" This is as simple as exemplified in the \s-1SYNOPSIS\s0. In fact, there's nothing more to know. All you have to do is: .PP .Vb 1 \& throw XML::SAX::Exception::MyException( Message => 'Something went wrong' ); .Ve .PP and voila, you've thrown an exception which can be caught in an eval block.
