Title: How To remove WhiteSpace

Hi,

I had the same problem.

First I though setting the feature    http://apache.org/xml/features/dom/include-ignorable-whitespace to false would solve the problem but then you always need a grammar.

 

Now I just traverse the tree and remove all empty textnodes :

 

private static void removeEmptyTextNodes(Element node) {
    Node el = node.getFirstChild();
    while (el != null) {
      Node next = el.getNextSibling();
      if (el.getNodeType() == Node.TEXT_NODE) {
        String str = el.getNodeValue().trim();
        if (str.equals("")) {
          node.removeChild(el);
        }
      } else {
        if (el.getNodeType() == Node.ELEMENT_NODE) {
          removeEmptyTextNodes((Element)el);
        }
      }
      el = next;
    }
  }

Hello All,
    I constructed a Dom from an xml file.
    I had counted the number of children for the rootnode.
    I am getting #text elements are also the children of root node.
    How to remove this #text?
    This empty element is coming between one element and the other element.

Thanks in Advance,
B.HARIKRISHNA
