private static void removeWhitespaceInner(Node n, Node parent) {
 // This n is removed from the parent if n is a whitespace node
 if (parent != null && n instanceof Text && (!(n instanceof CDATASection))) {

  if (t.getData().matches("[ \t\n]*")) {
   parent.removeChild(t);
  }
 }
 if (n.hasChildNodes()) {
  int length = n.getChildNodes().getLength();
  List<Node> toBeProcessed = new ArrayList<Node>();
  // We collect all the nodes to iterate as the child nodes will change 
  // upon removal
  for (int i = 0; i < length; i++) {
   toBeProcessed.add(n.getChildNodes().item(i));
  }
  // This changes the child nodes, but the iterator of nodes never changes
  // meaning that this is safe
  for (Node childNode : toBeProcessed) {
   removeWhitespaceInner(childNode, n);
  }
 }
}
