NAME

SGML::PI - an SGML, XML, or HTML document processing instruction

SYNOPSIS

$data = $pi->data;

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

$pi->iter;

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

DESCRIPTION

SGML::PI objects are loaded by SGML::SPGrove. An SGML::PI contains the data in a Processing Instruction (PI).

$pi->data returns the data of the PI object.

$pi->as_string returns an empty string.

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

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

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

children_accept and children_accept_gi do nothing.
