Method

Element[]getChildElements(Element element, String namespace, String localName)
Returns all Element children of an Element that belong to the given namespace and have the given local name. 
ArrayList elements = new ArrayList();
NodeList nodeList = element.getChildNodes();
for (int i = 0; i < nodeList.getLength(); i++) {
    Node node = nodeList.item(i);
    if (node instanceof Element && namespace.equals(node.getNamespaceURI())
            && localName.equals(node.getLocalName())) {
        elements.add(node);
return (Element[]) elements.toArray(new Element[elements.size()]);
ListgetChildElements(Element element, String tag)
get single element by tag name. 
return toElements(element.getChildNodes(), tag);
ListgetChildElements(Element element, String tagName)
get Child Elements 
List<Element> elements = getElementList(element);
int numElements = elements.size();
List<Element> childElements = new ArrayList<Element>(numElements);
