Summary and Resources

In this article, you've taken a very basic look at the use of DOM in the JavaScript of a Web page. You can use the same principles anywhere JavaScript is in use, such as within an XSLT style sheet.

The Document Object Model represents elements, text, and other types of nodes within an XML document as a series of parent-child relationships. By manipulating these individual nodes, you can affect the page itself. In addition to DOM Core methods, an XHTML page can also expose properties and methods that are part of the DOM HTML module, which attempts to integrate many of the DHTML properties that programmers have been using for years.
