Here's the snipet. Every time it goes into the loop the elements are read but not added and there value is always null

public static List<Element> getChildrenByTagName() throws XPathExpressionException, ParserConfigurationException, SAXException, IOException {


DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse("Input.xml");

XPathFactory xpathFactory = XPathFactory.newInstance();
XPath xpath = xpathFactory.newXPath();
xpath.setNamespaceContext(new wdXMLNamespaceResolver(doc, false));
//XPathExpression xPathQuery = xpath.compile(query);

Node links = (Node)xpath.evaluate("/userdata/David/tester[@id='1000']", doc, XPathConstants.NODE);

List<Element> nodeList = new ArrayList<Element>();
for (Node child = links.getFirstChild(); child != null; child = child.getNextSibling()) {
if (child.getNodeType() == Node.ELEMENT_NODE ) {
nodeList.add((Element) child);


}


Please help .. In a new role


}
// System.out.println(nodeList.toString()); //Testing
return nodeList;

}

Welcome to JR! Before you get any answers on this forum, you might want to change your display name.

i'd also suggest you learn to use the 'code' tags. When pasting source, just click the little "code" button and the tags will auto-populate. then paste your source code between them. It preserves the indentation and makes reading what you have MUCH easier.

I'd add them to your post, but you don't have proper indentation anyway, so it won't matter.

How do you know it's null? Where does the null appear? You can't tell that from your code (which is difficult to read without the code tags; please use the "edit" button and add code tags).
 
It is sorta covered in the JavaRanch Style Guide.
