Answer 1

Try to use XPath expression. See sample code below.

Document doc = dBuilder.parse(new ByteArrayInputStream(responseXML.getBytes()));
doc.getDocumentElement().normalize();
XPath xPath =  XPathFactory.newInstance().newXPath();

String expression = "/ns6:ReadPersonReturn/ns6:object/ns3:Person/ns3:Phone/ns3:item";
NodeList nodes = (NodeList) xPath.compile(expression).evaluate(doc, XPathConstants.NODESET);
Element secondNode = null;
if(nodes != null && nodes.getLength() > 0){
    secondNode = (Element) leadCloudPingRecordNodes.item(i);
}
