DOM for Web Services, Part 1

In this first article of a three-part series, I offer a tutorial of the W3C Document Object Model (DOM) with particular application to web services. Here we will discuss, explain, and demonstrate what DOM can do for the XML authoring and processing required by web service applications. We will consider each of the three DOM levels and apply the DOM functionality to explain why, when, and how to use the various features that W3C DOM offers. Each level provides a certain collection of XML authoring and processing features. Levels 1 and 2 have become W3C recommendations, while the third level is currently a working draft at W3C.
