Generating XML Documents

You now know how to write Java programs that read XML. Let us now turn to the opposite process, producing XML output. Of course, you could write an XML file simply by making a sequence of print calls, printing the elements, attributes, and text content, but that would not be a good idea. The code is rather tedious, and you can easily make mistakes if you don't pay attention to special symbols (such as " or <) in the attribute values and text content.

A better approach is to build up a DOM tree with the contents of the document and then write out the tree contents. To build a DOM tree, you start out with an empty document. You can get an empty document by calling the newDocument method of the DocumentBuilder class.
