Part III: XML and the Document Object Model (DOM)

1. Generating a DOM from XML data

Reading an XML Document into a DOM

Create the Skeleton
Import the Required Classes

Looking Ahead

2. Generating XML from an Arbitrary Data Structure

How It Works
Modify the "Parser" to Generate SAX Events
Implement the org.xml.sax.Parser Interface
Create a Factory
Wire Your "Parser" to an XmlDocumentBuilder
Write it Out
Run It
