I think the XPath should do the trick.

Provided you already have parsed the document as org.w3c.dom.Document:

String expression = "/rootnode/foo/bar";
NodeList nodeList = (NodeList)   xPath.compile(expression).evaluate(document, XPathConstants.NODESET);
for (int i = 0; i < nodeList.getLength(); i++) {
    System.out.println(nodeList.item(i).getFirstChild().getNodeValue()); 
}
