For nodes that are blank node.getChildNodes()==null
For nodes that only contain whitespace:

isBlank=true;
NodeList nl=node.getChildNodes();
for(int i=0;i<nl.getLength();i++) {
  Node eachItem=nl.item(i);
  if (!eachItem instanceof TextElement) {
     isBlank=false;
     break;
  } else {
     if (eachItem.getNodeValue().trim().length>0) {
       isBlank=false;
       break;
     }
  }
}

Not sure if i understand that code example although i think


>>if (eachItem.getNodeValue().trim().length>0) {


should be

if (eachItem.getNodeValue().trim().length()>0) {

You may want to add the blank nodes to a List so you know which ones to avoid

Sorry, didn't compile code.  Here is correct version:

        boolean isBlank=true;
        NodeList nl=node.getChildNodes();
        for(int i=0;i<nl.getLength();i++) {
            Node eachItem=nl.item(i);
            if (!(eachItem instanceof Text)) {
                isBlank=false;  //This node in the tree is NOT a leaf (i.e. it has children that are Element Nodes)
                break;
            } else {
                if (eachItem.getNodeValue().trim().length()>0) {
                    isBlank=false;  //This node has non-whitespace data as children
                    break;
                }
            }
           
        }
