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 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.
