NAME ^

SGML::Grove - an SGML, XML, or HTML document

SYNOPSIS ^

  use SGML::Grove;
  $grove = A::GroveBuilder->new ($sysid);
  $root = $grove->root;
  $errors = $grove->errors;
  $entities = $grove->entities;
  $notations = $grove->notations;

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

  $grove->iter;

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

DESCRIPTION ^

SGML::Grove represents a loaded document instance returned from a grove building or parsing module, i.e. for SGML documents this may be SGML::SPGroveBuilder. The returned grove contains the root, or top, element of the document and an array of any warnings or errors that may have been generated while parsing the document.

$grove->root returns the SGML::Element of the outermost element of the document.

$grove->errors returns a reference to an array containing any errors generated while parsing the document.

$grove->entities returns a reference to a hash containing any entities referenced in this grove (as opposed to entities that may have been declared but not used).

$grove->notations returns a reference to an array containing any notations referenced in this grove.

$grove->as_string returns the entire grove as a string, possibly modified by $context. See SGML::SData and SGML::PI for more detail.

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

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

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

children_accept and children_accept_gi call accept and accept_gi, respectively, on the root element.
