xml::doctype::attdef(3)

NAME

XML::Doctype::AttDef - A class representing a definition
in an <!ATTLIST> tag

$attr = $elt->attribute( $name ) ;
$attr->name ;

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: $dtd = XML::Doctype::AttDef->new( $name, $type,; $default ) ;
default: ( $spec, $value ) = $attr->default ;
$attr->default( '#REQUIRED' ) ;
$attr->default( '#IMPLIED' ) ;
$attr->default( '', 'foo' ) ;
$attr->default( '#FIXED', 'foo' ) ;
Sets/gets the default value. This is a
quant: $attdef->quant( $q ) ;
$q = $attdef->quant ;
Sets/gets the attribute quantifier: '#REQUIRED', '#FIXED', '#IMPLIED', or ''.
name: $attdef->name( $name ) ;
$name = $attdef->name ;
Sets/gets this attribute name. Don't change the name while an attribute is in an element's attlist, since it will then be filed under the wrong name.
default_on_write: $attdef->default_on_write( $value ) ;
$value = $attdef->default_on_write ;; $attdef->default_on_write( $attdef->default ) ;
Sets/gets the value which is automatically output for this attribute if none is supplied to $writer->start Tag. This is typically used to set a document-wide default for #REQUIRED attributes (and perhaps plain attributes) so that the attribute is treated like a #FIXED tag and emitted with a fixed value.
The default_on_write does not need to be the same as the default unless the quantifier is #FIXED.

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