NAME

HTML::DOM::Element - A Perl class for representing elements in an HTML DOM tree

VERSION

Version 0.058

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 HTML::DOM.) 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 CSS::DOM::Style object, representing the contents of the 'style' HTML attribute.

And there is also the following non-DOM 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 (HTML::DOM::Attr).
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.
getElementsByClassName ( $names ): This finds all elements whose class attribute contains all the names in $names, which is a space-separated list; returning the elements 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 HTML::DOM::Node's method to trigger a DOMActivate event after a click.
