NAME¶
XML::Doctype::AttDef - A class representing a definition in an <!ATTLIST>
tag
SYNOPSIS¶
$attr = $elt->attribute( $name ) ;
$attr->name ;
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
-
$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->startTag. 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.
SUBCLASSING¶
This object uses the fields pragma, so you should use base and fields for any
subclasses.
