Hi,
      I am having an xml file like the following
<application>
        <row>
            <id>4</id>
            <name>CLIENTDEMO</name>
            <description/>
        </row>
</application>
        I had written java code to iterate thru this xml and retrieve the values . when the element <description> came I am getting null pointer xception.

    Here is my code.
NodeList application = documentElement.getElementsByTagName("application");
    for (int i = 0; i < application.getLength(); i++)
        {

            NodeList nl = application.item(i).getChildNodes();
            {
                Node ch = application.item(i);
                NodeList nll = ch.getChildNodes();
                ArrayList applicationArrayList = new ArrayList();
                for (int j = 0; j < nll.getLength(); j++)
                {
                    Node chh = nl.item(j);
                    NodeList nlll = chh.getChildNodes();
                    //System.out.println("Animals = " + nlll.getLength());

                    for (int k = 0; k < nlll.getLength()-1; k++)
                    {
                        Node chhh = nlll.item(k);
                        System.out.println("NodeType 1"+ chhh.getNodeType());
                        if (chhh.getNodeType() == 1)
                        {
                            System.out.println("NodeType 1"+ chhh.getNodeName());
                            System.out.println("NodeType 1"             +chhh.getFirstChild().getNodeValue());
                                applicationArrayList.add(chhh.getFirstChild().getNodeValue());

                        }

                    }

                }


            }


        }

    How can I skip when i get null values in the xml??

regards,

ramu
