SAX::DocumentLocator(3) 				User Contributed Perl Documentation				   SAX::DocumentLocator(3)

XML::SAX::DocumentLocator - Helper class for document locators SYNOPSIS
my $locator = XML::SAX::DocumentLocator->new( sub { $object->get_public_id }, sub { $object->get_system_id }, sub { $reader->current_line }, sub { $reader->current_column }, sub { $reader->get_encoding }, sub { $reader->get_xml_version }, ); DESCRIPTION
This module gives you a tied hash reference that calls the specified closures when asked for PublicId, SystemId, LineNumber and ColumnNumber. It is useful for writing SAX Parsers so that you don't have to constantly update the line numbers in a hash reference on the object you pass to set_document_locator(). See the source code for XML::SAX::PurePerl for a usage example. API
There is only 1 method: "new". Simply pass it a list of closures that when called will return the PublicId, the SystemId, the LineNumber, the ColumnNumber, the Encoding and the XMLVersion respectively. The closures are passed a single parameter, the key being requested. But you're free to ignore that. perl v5.16.2 2009-10-10 SAX::DocumentLocator(3)

XML::SAX::Exception - Exception classes for XML::SAX SYNOPSIS
throw XML::SAX::Exception::NotSupported( Message => "The foo feature is not supported", ); DESCRIPTION
This module is the base class for all SAX Exceptions, those defined in the spec as well as those that one may create for one's own SAX errors. There are three subclasses included, corresponding to those of the SAX spec: XML::SAX::Exception::NotSupported XML::SAX::Exception::NotRecognized XML::SAX::Exception::Parse Use them wherever you want, and as much as possible when you encounter such errors. SAX is meant to use exceptions as much as possible to flag problems. CREATING NEW EXCEPTION CLASSES
All 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 you may also inherit from that instead of from the base class. THROWING EXCEPTIONS
This 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. perl v5.12.1 2010-07-05 XML::SAX::Exception(3)
