Using XML with Legacy Business Applications

main in XMLToCSVBasic.java

Let's start with this bit of pseudocode:

Set up DOM XML environment (dependent on implementation)
Load input XML Document (dependent on implementation)

In JAXP, we build a DOM Document with the DocumentBuilder class. However, we can't just declare a DocumentBuilder; we must get one from a DocumentBuilderFactory. A real-world analogy would be a metal worker who wants to build a barbecue for his backyard. He needs tools to build it, and the ultimate source of those tools is a tool and die maker. So, we declare a tool and die maker (the DocumentBuilderFactory), who then makes us a tool (the DocumentBuilder) that we can use to build our barbecue (the Document). Here's how the Java code looks.
