O que acham do seguinte código:

package br.com.yahoo.renato3110.xmlvomiter.demo;

import java.util.*;
import br.com.yahoo.renato3110.xmlvomiter.*;

public class VomitDemo {

class Evangelion implements Vomitable {
		public String name;
		public String type;
		public String pilot;
		
		public Evangelion (String name, String type, String pilot) {
			this.name = name;
			this.type = type;
			this.pilot = pilot; 
		}
		
		public String getAsXML(XMLFormatter f){

StringBuffer sb = new StringBuffer();

sb.append(f.formatAs("type", type)).append("\n");
			sb.append(f.formatAs("pilot", pilot));

f.addAttribute("name", name);
			f.setIndent(true);

return f.formatAs("evangelion", sb.toString());

}
	}
    
    public VomitDemo() {
    	
		List l = new LinkedList();
		
		l.add(new Evangelion("Eva-00", "Prototype", "Rei Ayanami"));
		l.add(new Evangelion("Eva-02", "Production", "Asuka Langley Soryu"));
		l.add(new Evangelion("Eva-03", "S2 Engine", "Touji Suzuhara"));
		l.add(new Evangelion("Eva-04", "S2 Engine", "Kaworu?"));		
		l.add(new Evangelion("Eva-05", "Mass Production", "Dummy Plug"));
		l.add(new Evangelion("Eva-06", "Mass Production", "Dummy Plug"));
		l.add(new Evangelion("Eva-07", "Mass Production", "Dummy Plug"));
		l.add(new Evangelion("Eva-08", "Mass Production", "Dummy Plug"));
		l.add(new Evangelion("Eva-09", "Mass Production", "Dummy Plug"));
		l.add(new Evangelion("Eva-10", "Mass Production", "Dummy Plug"));
		l.add(new Evangelion("Eva-11", "Mass Production", "Dummy Plug"));
		l.add(new Evangelion("Eva-12", "Mass Production", "Dummy Plug"));
		l.add(new Evangelion("Eva-13", "Mass Production", "Dummy Plug"));
		
		XMLFormatter f = new XMLFormatter();
		
		f.setIndent(true);
		
		f.addCData("Neon Genesis Evangelion\nGod is in his sky. It'a all right with the world.");
		f.addComment("Zankoku na tenshi no teeze\nShounen yo shinwa ni nare");
		                 
		
		f.addElement("evangelions", "default-evangelion", l);

f.addDeclaration("<?xml version=\"1.0\"?>");
		f.addDeclaration("");
		
		System.out.println(f.formatAs("evangelion-world"));
		
		// No caso abaixo não precisamos definir um elemento pai de evangelions, mas o conteúdo
		// adicionado por addCData ficaria fora do elemento raiz o que invalida um XML 
		 
		// System.out.println(f.getDeclarations() + "\n" + f.getContent());                   
    }
    
    public static void main(String[] args) {
    	new VomitDemo();
    }
}

Que gerou a seguinte saída:

<?xml version="1.0"?>

Dífícil? Fácil? Horrível? Legalzinho? Este tópico é horrível?
