NAME¶
XML::Doctype::ElementDecl - A class representing an <!ELEMENT> tag
SYNOPSIS¶
$elt = $dtd->element( 'foo' ) ;
$elt->name() ;
$elt->attr( 'foo' ) ;
DESCRIPTION¶
This module is used to represent <!ELEMENT> tags in an XML::Doctype
object. It contains <!ATTLIST> tags as well.
STATUS¶
This module is alpha code. It's developed enough to support XML::ValidWriter,
but need a lot of work. Some big things that are lacking are:
METHODS¶
- new
-
# Undefined element constructors:
$dtd = XML::Doctype::ElementDecl->new( $name ) ;
$dtd = XML::Doctype::ElementDecl->new( $name, undef, \@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 element 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 elements of this type.
Right now, this must be called only when an element's end tag is emitted. It
can be broadened to be incremental if need be.
SUBCLASSING¶
This object uses the fields pragma, so you should use base and fields for any
subclasses.
