NAME

XML::Doctype::ElementDecl - A class representing an <!ELE
MENT> tag

$elt = $dtd->element( 'foo' ) ;
$elt->name() ;
$elt->attr( 'foo' ) ;

This module is used to represent <!ELEMENT> tags in an
XML::Doctype object. It contains <!ATTLIST> tags as well.

This module is alpha code. It's developed enough to sup
port XML::ValidWriter, but need a lot of work. Some big
things that are lacking are:

new: # Undefined element constructors:
$dtd = XML::Doctype::ElementDecl->new( $name ) ;
$dtd = XML::Doctype::ElementDecl->new( $name, un; def, @attdefs ) ;; # Defined element constructors
$dtd = XML::Doctype::ElementDecl->new( $name,; @kids, @attdef ) ;
$dtd = XML::Doctype::ElementDecl->new( $name, [],; @attdefs ) ;
add_attdef: $elt_decl->add_attdef( $att_def ) ;
attdef: $attr = $elt->attdef( $name ) ;
Returns the XML::Doctype::AttDef named by $name or undef if there is no such attribute.
attdefs: $attdefs = $elt->attdefs( $name ) ;
Returns the list of XML::Doctype::AttDef instances associated with this element.
attribute_names: Returns a list of the attdefs' names.
child_names: @names = $elt->child_names ;
Returns a list of names of elements in this element decl's content model.
is_declared: if ( $elt_decl->is_declared ) ...
$elt_decl->is_declared( 1 ) ;
Returns TRUE if there is any data defined in the ele ment other than name and attributes or if is_declared has been set by calling is_declared( 1 ) or passing DECLARED => 1 to new().
is_empty is_any is_mixed name: $n = $elt_decl->name ;
Gets the name of the element.
validate_content: $v = $elt_decl->validate_content( @seq ) ;
Takes an ARRAY ref of tag names (or '#PCDATA') and checks to see if it would be valid content for ele ments of this type.
Right now, this must be called only when an element's end tag is emitted. It can be broadened to be incre mental if need be.

This object uses the fields pragma, so you should use base
and fields for any subclasses.
