How to remove #text from my Node parsing in Java dom xml parsing Code Answer

Hello Developer, Hope you guys are doing great. Today at Tutorial Guruji Official website, we are sharing the answer of How to remove #text from my Node parsing in Java dom xml parsing without wasting too much if your time.

The question is published on by Tutorial Guruji team.

So I have the following code which I pretty much copied from here. But the problem is my text nodes do not contain any text they just have attributes. So I have like

<Random name="Katie" num="5"></Random>

and I’m using this code to parse it:

  private void listNodes(Node node, String indent)
  {
    String nodeName = node.getNodeName();
    System.out.println(indent + " Node is: " + nodeName);
    
    if(node instanceof Element && node.hasAttributes())
    {
      System.out.println(indent + "Attributes are: ");
      NamedNodeMap attrs = node.getAttributes();
      for (int i = 0; i < attrs.getLength(); i++) 
      {
        Attr attribute = (Attr) attrs.item(i);
        System.out.println(indent + attribute.getName() + "=" + attribute.getValue());
      }
    }
    
    NodeList list = node.getChildNodes(); 
    
    if (list.getLength() > 0) 
    {
      for (int i = 0; i < list.getLength(); i++)
      {
        listNodes(list.item(i), indent + " "); 
      } 
    }
  }

For some reason my empty text nodes all say

Node is: #text

Does anyone know how to skip empty node text when parsing the xml file?

Thanks,

Josh

Answer

With DTD validation you can have the parser automatically suppress the whitespace between elements. However to modify your specific implementation, you can test for Text nodes, and ignore them if they are empty.

private void listNodes(Node node, String indent)
{
    if (node instanceof Text) {
        String value = node.getNodeValue().trim();
        if (value.equals("") ) {
            return;
        }
    }

    String nodeName = node.getNodeName();
    System.out.println(indent + " Node is: " + nodeName);
    ...
