NAME
     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 clo-
     sures 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 Column-
     Number, the Encoding and the XMLVersion respectively.

     The closures are passed a single parameter, the key being requested. But
     you're free to ignore that.
