| 97 | =head1 NAME | |||
| 98 | ||||
| 99 | XML::SAX::DocumentLocator - Helper class for document locators | |||
| 100 | ||||
| 101 | =head1 SYNOPSIS | |||
| 102 | ||||
| 103 | my $locator = XML::SAX::DocumentLocator->new( | |||
| 104 | sub { $object->get_public_id }, | |||
| 105 | sub { $object->get_system_id }, | |||
| 106 | sub { $reader->current_line }, | |||
| 107 | sub { $reader->current_column }, | |||
| 108 | sub { $reader->get_encoding }, | |||
| 109 | sub { $reader->get_xml_version }, | |||
| 110 | ); | |||
| 111 | ||||
| 112 | =head1 DESCRIPTION | |||
| 113 | ||||
| 114 | This module gives you a tied hash reference that calls the | |||
| 115 | specified closures when asked for PublicId, SystemId, | |||
| 116 | LineNumber and ColumnNumber. | |||
| 117 | ||||
| 118 | It is useful for writing SAX Parsers so that you don't have | |||
| 119 | to constantly update the line numbers in a hash reference on | |||
| 120 | the object you pass to set_document_locator(). See the source | |||
| 121 | code for XML::SAX::PurePerl for a usage example. | |||
| 122 | ||||
| 123 | =head1 API | |||
| 124 | ||||
| 125 | There is only 1 method: C<new>. Simply pass it a list of | |||
| 126 | closures that when called will return the PublicId, the | |||
| 127 | SystemId, the LineNumber, the ColumnNumber, the Encoding | |||
| 128 | and the XMLVersion respectively. | |||
| 129 | ||||
| 130 | The closures are passed a single parameter, the key being | |||
| 131 | requested. But you're free to ignore that. | |||
