Question

In my xml there can be empty tags like

<name/>

The problem is that when I parse the xml, I am getting null pointer exception when I reach this line in the xml. Currently I am fetching like this:

employees.item(k).getFirstChild().getNodeValue()

How should I check tags like this in my parsing file? Please help me out.

Answer 1

Better to check NULL instead of using try..catch block:

if(employees.item(k).getFirstChild() != null) {
    employees.item(k).getFirstChild().getNodeValue()
}

Just a sample code to answer question, doesn’t make it at best performance.
