Depth of a xml node

Hi;
I have to write an java code, which calculates the maximal depth of a xml node, using DOM.
Has anyone an idea?

your code implies that the depth count begin from the children to the parent. But in my case I know the parent node (root) but I dont know how many children and grandchildren it has.You basically have to search for your Node from the root and keep track of a 'depth' number. Recursion is your friend:
public int getNodeDepth(Node node, Node wanted, int depth) {
   if (node == null) return -1; // nothing to look for here, please walk on
   if (node == wanted) return depth; // found it
   for (Node child : node.getChildren()) {
      int found= getNodeDepth(child, wanted, depth+1)
      if (found >= 0) return found;
   return -1; // not found
}You have to call this method as getNodeDepth(root, wanted, 0) to start the circus.
kind regards,
Jos
ps. warning, untested code
