NAME
HTML::DOM::Node - A Perl class for representing the nodes of an HTML DOM tree
VERSION
Version 0.055
SYNOPSIS
use HTML::DOM::Node ':all'; # constants
use HTML::DOM;
$doc = HTML::DOM->new;
$doc->isa('HTML::DOM::Node'); # true
$doc->nodeType == DOCUMENT_NODE; # true
$doc->firstChild;
$doc->childNodes;
# etcDESCRIPTION
This is the base class for all nodes in an HTML::DOM tree. (See "CLASSES AND DOM INTERFACES" in HTML::DOM.) It implements the Node interface, and, indirectly, the EventTarget interface (see HTML::DOM::EventTarget.
METHODS
Attributes
The following DOM attributes are supported:
- nodeName
- nodeType
-
These two are implemented not by HTML::DOM::Node itself, but by its subclasses.
- nodeValue
- parentNode
- childNodes
- firstChild
- lastChild
- previousSibling
- nextSibling
- attributes
- ownerDocument
- namespaceURI
- prefix
- localName
-
Those last three always return nothing.
There is also a _set_ownerDocument method, which you probably do not need to know about.
Other Methods
See the DOM spec. for descriptions of most of these. The first four automatically trigger mutation events. (See HTML::DOM::Event::Mutation.)
- insertBefore
- replaceChild
- removeChild
- appendChild
- hasChildNodes
- cloneNode
- normalize
- hasAttributes
- isSupported
- trigger_event
-
This overrides HTML::DOM::EventTarget's (non-DOM) method of the same name, so that the document's default event handler is called.
- as_text
- as_HTML
-
These two (non-DOM) methods of HTML::Element are overridden, so that they work correctly with comment and text nodes.
