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??
