NAME

6       XML::SAX::Exception - Exception classes for XML::SAX
7

SYNOPSIS

9         throw XML::SAX::Exception::NotSupported(
10                 Message => "The foo feature is not supported",
11                 );
12

DESCRIPTION

14       This module is the base class for all SAX Exceptions, those defined in
15       the spec as well as those that one may create for one's own SAX errors.
16
17       There are three subclasses included, corresponding to those of the SAX
18       spec:
19
20         XML::SAX::Exception::NotSupported
21         XML::SAX::Exception::NotRecognized
22         XML::SAX::Exception::Parse
23
24       Use them wherever you want, and as much as possible when you encounter
25       such errors. SAX is meant to use exceptions as much as possible to flag
26       problems.
27

CREATING NEW EXCEPTION CLASSES

29       All you need to do to create a new exception class is:
30
31         @XML::SAX::Exception::MyException::ISA = ('XML::SAX::Exception')
32
33       The given package doesn't need to exist, it'll behave correctly this
34       way. If your exception refines an existing exception class, then you
35       may also inherit from that instead of from the base class.
36

THROWING EXCEPTIONS

38       This is as simple as exemplified in the SYNOPSIS. In fact, there's
39       nothing more to know. All you have to do is:
40
41         throw XML::SAX::Exception::MyException( Message => 'Something went wrong' );
42
43       and voila, you've thrown an exception which can be caught in an eval
44       block.
