voidprintChildElements(Element root, PrintStream out, boolean recurse, String prefix)
Whenever you'd need to print a configuration node and/or its children. 
out.print(prefix + "<" + root.getNodeName());
NamedNodeMap attrs = root.getAttributes();
Node node;
for (int i = 0; i < attrs.getLength(); i++) {
    node = attrs.item(i);
    out.print(" " + node.getNodeName() + "=\""
            + node.getNodeValue() + "\"");
out.println(">");
String data = getText(root);
if (data != null && data.trim().length() > 0)
    out.println(prefix + "\t" + data);
data = getCData(root);
if (data != null && data.trim().length() > 0)
    out.println(prefix + "\t<![CDATA[" + data + "]]>");
NodeList nodes = root.getChildNodes();
for (int i = 0; i < nodes.getLength(); i++) {
    node = nodes.item(i);
    if (node.getNodeType() == Node.ELEMENT_NODE) {
        if (recurse)
            printChildElements((Element) node, out, recurse, prefix
                    + "\t");
        else
            out.println(prefix + node.getNodeName());
