Method

Node[]convertToArray(NodeList list)
convert To Array 
int length = list.getLength();
Node[] copy = new Node[length];
for (int n = 0; n < length; ++n)
    copy[n] = list.item(n);
return copy;
ListconvertToElementList(org.w3c.dom.NodeList _nodeList)
Convert a NodeList to a Java List of Element s. 
List<org.w3c.dom.Element> elemList = new ArrayList<>();
for (int i = 0; i < _nodeList.getLength(); i++) {
    Element elem = (org.w3c.dom.Element) _nodeList.item(i);
    elemList.add(elem);
return elemList;
ListcopyNodeList(NodeList nodeList)
Copy a given NodeList into a List 
ArrayList<Node> copy = new ArrayList<Node>();
int length = nodeList.getLength();
for (int i = 0; i < length; i++) {
    copy.add((Node) nodeList.item(i));
return copy;
CollectioncreateNodeCollection(final NodeList nodeList)
create Node Collection 
return new Collection<Node>() {
    @Override
    public int size() {
        return nodeList.getLength();
    @Override
    public boolean isEmpty() {
        return nodeList.getLength() > 0;
...
ListcreateRealNodeList(NodeList nodeList)
create Real Node List 
List<Node> realNodeList = new LinkedList<Node>();

...
booleanequalNodes(NodeList sourceNodeList, NodeList targetNodeList)
equal Nodes 
ArrayList sourceNodes = new ArrayList();
ArrayList targetNodes = new ArrayList();

NodeList node = config.getElementsByTagName(tag);
return check1Most(node, tag, required);
