NAME

SGML::SData - an SGML, XML, or HTML document SData replacement

SYNOPSIS

$sdata = SGML::SData->new ($replacement[, $entity_name]);

$name = $sdata->name;
$data = $sdata->data;

$sdata->as_string([$context, ...]);

$sdata->iter;

$sdata->accept($visitor, ...);
$sdata->accept_gi($visitor, ...);
$sdata->children_accept($visitor, ...);
$sdata->children_accept_gi($visitor, ...);

DESCRIPTION

An SGML::SData contains the entity name and replacement value of a character entity reference.

$sdata->name returns the entity name of the SData object.

$sdata->data returns the data of the SData object.

The Perl module Text::EntityMap can be used to map commonly used character entity sets to common output formats.

$sdata->as_string([$context, ...]) returns data surrounded by brackets (`[ ... ]') unless $context->{sdata_mapper} is defined, in which case it returns the result of calling the sdata_mapper subroutine with data and the remaining arguments. The actual implementation is:

&{$context->{sdata_mapper}} ($self->data, @_);

$sdata->iter returns an iterator for the sdata object, see Class::Visitor for details.

$sdata->accept($visitor[, ...]) issues a call back to $visitor->visit_SGML_SData($sdata[, ...]). See examples visitor.pl and simple-dump.pl for more information.

$sdata->accept_gi($visitor[, ...]) is implemented as a synonym for accept.

children_accept and children_accept_gi do nothing.
