Summary:  Even before there was XML, there was the Document Object Model, or DOM. It allows a developer to refer to, retrieve, and change items within an XML structure, and is essential to working with XML. In this tutorial, you will learn about the structure of a DOM document. You will also learn how to use Java™ technology to create a Document from an XML file, make changes to it, and retrieve the output.

Document Object Model summary

Summary

The DOM is a language- and platform-independent API designed for working with XML data. It is a tree-based API that loads all of the data into memory as a parent-child hierarchy of nodes, which may be elements, text, attributes, or other node types.

The DOM API allows a developer to read, create, and edit XML data. This tutorial has covered the concepts behind the DOM and illustrated them with examples in Java code. Implementations of the DOM are also available in C++, Perl, and other languages.
