The getNextNode will skip your desired endNode recursively if its a parent node.

Perform the conditional break check inside of the getNextNode instead:

var getNextNode = function(node, skipChildren, endNode){
  //if there are child nodes and we didn't come from a child node
  if (endNode == node) {
    return null;
  }
  if (node.firstChild && !skipChildren) {
    return node.firstChild;
  }
  if (!node.parentNode){
    return null;
  }
  return node.nextSibling 
         || getNextNode(node.parentNode, true, endNode); 
};

and in while statement:

while (startNode = getNextNode(startNode, false , endNode));
