In the last days in a my program, I should substitute a single node with a set of Node. The DOM interface (in this program I’m using the Xerces library) doesn’t provides an useful method to replace a single Node to a set of Nodes.

For apply this piece of code you should have:

• parent node: The parent of the node that you want substitute;
• target node: The node that you want substitute;
• newNodes nodes: A set of nodes that you want add to the place of target node;

The code is the follow:

   1:  Node previous = null;

   2:  for(int i = newNodes.size() -1 ; i >= 0 ; i--) {

   3:      Node current = newNodes.get(i);

   4:  

   5:      if(i == newNodes.size() -1) {

   6:          parent.replaceChild(current, target);

   7:      } else {

   8:          parent.insertBefore(current, previous);

   9:      }

  10:      previous = current;

  11:  }
