Class XmlBuilder

java.lang.Object

net.sf.practicalxml.builder.XmlBuilder

public class XmlBuilder
extends Object

A tool for building XML, avoiding the mistakes of simple text output and the hassle of the DOM API. Primarily intended for building small snippets of XML for unit tests, but usable for all types of output.

This class takes a declarative approach to creating XML, using static factory methods to create Node objects. These are a lightweight representation of the DOM Node, focused on creation rather than manipulation. You can also append children to nodes imperatively, using the methods in this class to create the node objects.

This is best explained by example. To create the following XML:

You would have a program that looks like this:
