[jdom-interest] Namespaces and XMLOutputter

[Jason Hunter]

It works on my machine.  I saved your file to ns.xml, and ran this code
on it:

import java.util.*;
import org.jdom.*;
import org.jdom.input.*;
import org.jdom.output.*;

public class Tester2 {

  public static void main(String[] args) throws Exception {
    Document d = new SAXBuilder().build(args[0]);
    XMLOutputter outp = new XMLOutputter("", false);
    outp.output(d, System.out);
  }
}

Here's the output:

% java Tester2 ns.xml
<?xml version="1.0" encoding="UTF-8"?>
<a:messagelist xmlns:a="http://www.a.com" xmlns:b="http://www.b.com"
xmlns:c="http://www.c.com">
<b:message1>
<c:item1 value="500" />
</b:message1>
</a:messagelist>C:/tmp/jdom 30 %
