XML::SAX::DocumentLocator - phpMan

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.
