SYNOPSIS

            

              
              
use HTML::Native;
my $elem = HTML::Native->new (
  a => { class => "active", href => "/home" },
  "Home"
);
my $attrs = \%$elem;
print $attrs;
# prints " class="active" href="/home""
use HTML::Native::Attributes;
my $attrs = HTML::Native::Attributes->new ( {
  class => "active",
  href => "/home",
} );
print $attrs;
# prints " class="active" href="/home""
$attrs->{class}->{nav} = 1;

DESCRIPTION

An HTML::Native::Attributes object represents a set of HTML element attributes belonging to an HTML::Native object. It will be created automatically by HTML::Native as necessary; you probably do not ever need to manually create an HTML::Native::Attributes object.

An HTML::Native::Attributes object is a tied hash (see perltie). You can treat it as a normal Perl hash:

            

              
              
my $attrs = HTML::Native::Attributes->new ( { href => "/home" } );
print $attrs->{home};
# prints "/home"
            
          

Any value stored in the hash will be automatically converted into a new HTML::Native::Attribute object, and can be transparently accessed either as a scalar, or as a hash, or as an array. For example:

            

              
              
my $attrs = HTML::Native::Attributes->new();
$attrs->{class} = "error";
$attrs->{class}->{fatal} = 1;
push @{$attrs->{class}}, "internal";
print $attrs->{class};
# prints "error fatal internal";
            
          

See HTML::Native::Attribute for more documentation and examples.

SUBCLASSING

When subclassing HTML::Native::Attributes, you may wish to override the class that is used by default to hold new attributes. You can do this by overriding the new_attribute() method:

new_attribute()

            

              
              
$attr = $self->new_attribute ( <value> )
            
          

The default implementation of this method simply calls HTML::Native::Attribute->new():

            

              
              
return HTML::Native::Attribute->new ( shift );
