If you are trying to parse an xml file something like this could help you out:

DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();

Document doc = dBuilder.parse(file);
XPath xPath = XPathFactory.newInstance().newXPath();

String expression = "//pqr/@ref1";  // This line defines the element or attribute that you want to retrieve
Node node = (Node) xPath.compile(expression).evaluate(doc, XPathConstants.NODE);
String nodeValue = node.getTextContent();

If your xml file has repeating elements and attributes you might want to store your values in a NodeList. For that you could use:

NodeList nodeList = (NodeList) xPath.compile(expression).evaluate(doc, XPathConstants.NODESET);
