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

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( $attdef->default ) ;
Sets/gets the value which is automatically output for this attribute if none is supplied to CW$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.
