RE: NullPointer Exception error while reading a XML

Hi –

I am getting following error while trying to read and display a content from an XML file.

Exception in thread “main” java.lang.NullPointerException
at firstPackage.ReadXml.main(ReadXml.java:33)

Code:


public class ReadXml {
public static void main(String[] args) throws ParserConfigurationException,

SAXException, IOException {
File xmlFile = new File(System.getProperty("user.dir") + "//Meals.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();

DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();

Document doc = dBuilder.parse(xmlFile);
NodeList nlXml = doc.getChildNodes();

Node nXml = nlXml.item(0);

Element element = (Element) nXml;
System.out.println("Meal: "

+ element.getElementsByTagName("Elements").item(0)

.getTextContent());
}
}

Could you please help with this error? Thanks so much!

Hi Aruna

If i was you then probably i would have used File.seprator instead of hardcoded slashes
new File(System.getProperty("user.dir")+File.seprator+ "Meals.xml");

Using this you can run your code on any platform

Thanks

Kapilag – I think it can read the XML file, thats not at all an issue. The problem is with the Node, dunno why that is passing the null value.
