SYNOPSIS

  use HTML::DOM;
  $doc = HTML::DOM->new;
  $elem = $doc->createElement('a');

  $elem->setAttribute('href', 'http://www.perl.org/');
  $elem->getAttribute('href');
  $elem->tagName;
  # etc

DESCRIPTION

This class represents elements in an HTML::DOM tree. It is the base class for other element classes (see CLASSES AND DOM INTERFACES in the HTML::DOM manpage.) It implements the Element and HTMLElement DOM interfaces.

METHODS

Constructor

You should normally use HTML::DOM's createElement method. This is listed here only for completeness:

  $elem = new HTML::DOM::Element $tag_name;

$elem will automatically be blessed into the appropriate class for $tag_name.

Attributes

The following DOM attributes are supported:

tagName

Returns the tag name.

id

title

lang

dir

className

These five get (optionally set) the corresponding HTML attributes. Note that className corresponds to the class attribute.

style

This returns a the CSS::DOM::Style manpage object, representing the contents of the 'style' HTML attribute.

content_offset: This contains the offset (in characters) within the HTML source of the element’s first child node, if it is a text node. This is set (indirectly) by HTML::DOM’s write method. You can also set it yourself.

Other Methods

getAttribute ( $name ): Returns the attribute's value as a string.
setAttribute ( $name, $value ): Sets the attribute named $name to $value.
removeAttribute ( $name ): Deletes the $named attribute.
getAttributeNode ( $name ): Returns an attribute node (the HTML::DOM::Attr manpage).
setAttributeNode ( $attr ): Sets the attribute whose name is $attr->nodeName to the attribute object itself. If it replaces another attribute object, the latter is returned.
removeAttributeNode ( $attr ): Removes and returns the $attr.
getElementsByTagName ( $tagname): This finds all elements with that tag name under the current element, returning them as a list in list context or a node list object in scalar context.
hasAttribute ( $name ): Returns true or false, indicating whether this element has an attribute named $name, even one that is implied.
click() (HTML 5): This triggers a click event on the element; nothing more.
trigger_event: This overrides the HTML::DOM::Node manpage's method to trigger a DOMActivate event after a click.
