The Document Object Model (DOM) is a programming interface for HTML, XML and SVG documents. It provides a structured representation of the document as a tree. The DOM defines methods that allow access to the tree, so that they can change the document structure, style and content. The DOM provides a representation of the document as a structured group of nodes and objects, possessing various properties and methods. Nodes can also have event handlers attached to them, and once an event is triggered, the event handlers get executed. Essentially, it connects web pages to scripts or programming languages.
Although the DOM is often accessed using JavaScript, it is not a part of the JavaScript language. It can also be accessed by other languages.
An introduction to the DOM is available.

Obsolete DOM interfaces
The Document Object Model has been highly simplified. To achieve this, the following interfaces present in the different DOM level 3 or earlier specification have been removed. It is still not very clear whether some may be reintroduced or not, but for the time being they have to be considered as obsolete and should be avoided:
HTML interfaces
A document containing HTML is described using the HTMLDocument
interface. Note that the HTML specification also extends the Document
interface.
An HTMLDocument
object also gives access to various features of browsers like the tab or the window, in which a page is drawn using the Window
interface, the Style
associated to it (usually CSS), the history of the browser relative to the context, History
. Eventually, Selection
is done on the document.

SVG data type interfaces
Here are the DOM API for data types used in the definitions of SVG properties and attributes.
Note: Starting in Gecko 5.0, the following SVG-related DOM interfaces representing lists of objects are now indexable and can be accessed ; in addition, they have a length property indicating the number of items in the lists: SVGLengthList
, SVGNumberList
, SVGPathSegList
, and SVGPointList
.
