The DOM breaks down the page into successively smaller parts until each element and its specific properties are identified. Dreamweaver MX 2004 integrates a subset of objects properties and methods from the W3C DOM Level 1 with a subset of properties from the Internet Explorer DOM. The resultant Dreamweaver DOM also includes some useful features not implemented in either of the other DOMs. Understanding nodes Dreamweaver s DOM makes available or exposes virtually every element on a Web page. The DOM is often described using a tree metaphor with the HTML document as the trunk. Instead of regarding the head and the body as the major branches however Dreamweaver s DOM like the W3C DOM uses four separate branches or nodes to divide the document DOCUMENT_NODE Enables access to objects directly relating to the overall document ELEMENT_NODE Contains references to all tags in the HTML document TEXT_NODE Describes the contiguous block of text within tags COMMENT_NODE Represents the comments
