Overrides existing values, if such exist. When multiple L</set_attribute>
calls are made against the same or overlapping selection sets, the final
Adds a value to an existing attribute, or creates one if the attribute does not
yet exist. You may call this method with either an Array or HashRef of Args.
-Here's the 'long form' HashRef:
-
$html_zoom
->select('p')
- ->set_attribute(class=>'paragraph')
- ->then
- ->add_to_attribute({name=>'class', value=>'divider'});
-
-And the exact same effect using the 'short form' Array:
-
- $html_zoom
- ->select('p')
- ->set_attribute(class=>'paragraph')
+ ->set_attribute({class => 'paragraph', name => 'test'})
->then
->add_to_attribute(class=>'divider');
->then
->remove_attribute('class');
