Node

a node in a document tree

DOM Level 1

Subclasses

Attr, Comment, Document, DocumentFragment, Element, Text

Constants

All nodes in an HTML document are instances of one of the Node

subclasses listed above. Every Node object has a

nodeType prop-

erty that specifies which of the subclasses it is an instance of. The

following constants are the legal values for

nodeType. Note that

these are static properties of

Node, not properties of individual

Node objects. They are not defined in Internet Explorer 4, 5, or 6;

in those browsers you must use the corresponding integer literals.

Node.ELEMENT_NODE = 1; // Element

Node.ATTRIBUTE_NODE = 2; // Attr

Node.TEXT_NODE = 3; // Text

Node.COMMENT_NODE = 8; // Comment

Node.DOCUMENT_NODE = 9; // Document

Node.DOCUMENT_FRAGMENT_NODE=11; // DocumentFragment

Properties

attributes[]

If this Node is an Element, the attributes property is a read-

only array of Attr objects that represent the attributes of the

element. The array can be indexed by number or by attribute

name. All HTML attributes have corresponding Element

properties, however, so it is uncommon to use the

attributes[] array.

childNodes[]

This read-only array of Node objects contains the children of

this node. If the node has no children, this property is a zero-

length array.

firstChild

This read-only property refers to the first child Node of this

node, or

null if the node has no children. ...
