Method

ListparseArray(final Node array)
Utility method to parse a 'array' node of the iTunes meta pList. 
final List<String> arrayList = new ArrayList<>();
if (array != null && array.getNodeType() == Node.ELEMENT_NODE && "array".equals(array.getNodeName())) {
    final NodeList children = array.getChildNodes();
    if (children != null) {
        for (int i = 0; i < children.getLength(); ++i) {
            final Node node = children.item(i);
            if (node != null && node.getNodeType() == Node.ELEMENT_NODE
                    && "dict".equals(node.getNodeName())) {
...
Map>parseDictionary(final Node dictionary)
Utility method to parse a 'dict' node of the iTunes meta pList. 
final Map<String, List<String>> iTunesMap = new HashMap<>();

voidparseModule(Node module, PrintWriter out)
Parses a giving module and writes it into the giving output stream 
ArrayList<Node> nodes = getNodesByName("Implements", module.getChildNodes());
if (nodes.size() == 0) {

MapparseProperties(Node doc)
Parse the childnodes of a node and look for <property> elements with attributes name and value. 
NodeList propertyNodes = doc.getChildNodes();
Map<String, String> properties = new HashMap<String, String>();
for (int i = 0; i < propertyNodes.getLength(); i++) {
    Node node = propertyNodes.item(i);
