Java Utililty Methods XML Node Tree

void dump(final Node node)
Recursively walks the DOM tree starting at the given Node printing the gory details of its construction to System.out.

doDump(System.out, node, 0);

void dump(Node node)
dump

System.out.println("Node: " + node.getNodeName());
NamedNodeMap nnm = node.getAttributes();
if (nnm != null) {
 for (int i = 0; i < nnm.getLength(); i++) {
 Node n = nnm.item(i);
 System.out.println(" " + n.getNodeName() + ":" + n.getNodeValue());

String dumpTree(Node node)
dump Tree

StringBuilder sb = new StringBuilder();
Stack<Node> stack = new Stack<Node>();
int level = 0;
while (node != null || !stack.isEmpty()) {

Node moveSubTree(Node from, Node to, Node context)
Copies all child nodes from the first Element tree into the second Element tree inserted before the given context node.

NodeList children = from.getChildNodes();
Node[] asArray = convertToArray(children);
Document fromDoc = from.getOwnerDocument();
Document toDoc = to.getOwnerDocument();
for (int n = 0; n < asArray.length; ++n) {
 from.removeChild(asArray[n]);
 if (fromDoc != toDoc)
 asArray[n] = toDoc.importNode(asArray[n], true);
