Method

NodeListgetNodeList(Node fatherNode, String nodeName)
Gets a node list from document, given the father node and the children node name. 
NodeList list = null;
if (((Element) fatherNode).getElementsByTagName(nodeName) != null) {
    list = ((Element) fatherNode).getElementsByTagName(nodeName);
return list;
NodeListgetNodeList(Node node, String tagName)
get Node List 
return getNodeList(NodeToElement(node), tagName);
NodeListgetNodeList(Node pNode, String tagName)
get Node List 
Element nodeElement = (Element) pNode;
NodeList theNodeList = nodeElement.getElementsByTagName(tagName);
return theNodeList;
ArrayListgetNodeList(NodeList nl, String[] names, int pos)
Get the list of nodes matching the given array of tag names in the given node list 
if ((nl == null) || (names.length - pos == 0))
    return null;
if (nl.getLength() == 0)
    return null;
ArrayList<Node> result = null;
if (names.length - pos == 1)
    result = new ArrayList<Node>();
for (int i = 0; i < nl.getLength(); i++) {
...
ListgetNodeList(NodeList nodeList)
get Node List 
List<Node> results = new ArrayList<Node>();
int len = nodeList.getLength();
for (int i = 0; i < len; i++) {
    Node node = nodeList.item(i);
    if (node instanceof Element) {
        results.add(node);
    } else {
        continue;
...
ListgetNodeList(NodeList nodeList)
Method that returns only the Element objects of the specified NodeList 
List<Element> nodes = new ArrayList<>();
for (int i = 0; i < nodeList.getLength(); i++) {
    Node node = nodeList.item(i);
    if (node instanceof Element)
        nodes.add((Element) node);
return nodes;

get Node List As List 
ArrayList<Node> l = new ArrayList<Node>();
for (int i = 0; i < nl.getLength(); i++) {
    l.add(nl.item(i));
return l;
ListgetNodeListByName(Node node, String name, List finalNodeList)
get Node List By Name 
NodeList nodeList = node.getChildNodes();
System.out.println("child node name: " + node.getNodeName());
if (nodeList == null)
    return null;
for (int i = 0; i < nodeList.getLength(); i++) {
    Node candNode = nodeList.item(i);
    if (candNode.getNodeName().equals(name)) {
        finalNodeList.add(candNode);
...
ListgetNodeListItems(NodeList nodeList)
get Node List Items 
List<Node> nodes = Lists.newArrayList();
for (int i = 0; i < nodeList.getLength(); i++) {
    Node node = nodeList.item(i);
    if (node.getLocalName() != null) {
        nodes.add(node);
return nodes;
...
intgetNodeListLength(NodeList list)
get Node List Length 
int length = 0;
try {
    length = list.getLength();
} catch (NullPointerException e) {
return length;
