Method

ElementgetChildElement(Node node, String childName)
get Child Element 
NodeList childNodes = node.getChildNodes();
int length = childNodes.getLength();
for (int i = 0; i < length; i++) {
    Node item = childNodes.item(i);
    if (item instanceof Element && item.getNodeName().equals(childName)) {
        return (Element) item;
return null;
ElementgetChildElement(Node parent, String childLocalName, String childNamespaceURI)
Returns the first child element that matches the given local name and namespace. 
if (parent != null) {
    NodeList children = parent.getChildNodes();
    for (int i = 0; i < children.getLength(); i++) {
        Node child = children.item(i);
        if (child.getNodeType() == Node.ELEMENT_NODE && childLocalName.equals(child.getLocalName())
                && childNamespaceURI.equals(child.getNamespaceURI())) {
            return (Element) child;
return null;
ElementgetChildElement(Node parent, String childName)
Gets a named child node. 
return (Element) getChildNode(parent, childName, Node.ELEMENT_NODE);
NodegetChildElement(Node parent, String elementName)
get Child Element 
NodeList childNodes = parent.getChildNodes();
for (int i = 0; i < childNodes.getLength(); i++) {
    Node childNode = childNodes.item(i);
    if (elementName.equals(childNode.getNodeName()))
        return childNode;
return null;
ElementgetChildElement(Node parent, String name)
Returns a node child with the specified tag name of the specified parent node, or null if no such child node is found. 
NodeList childList = parent.getChildNodes();
for (int i = 0; i < childList.getLength(); i++) {
    Node node = childList.item(i);
    if (node.getNodeType() == Node.ELEMENT_NODE
            && (name.equals(node.getLocalName()) || name.equals(node.getNodeName()))) {
        return (Element) node;
return null;
ElementgetChildElement(Node start, String name)
__UNDOCUMENTED__ 
NodeList nl = null;
if (start.getNodeType() == Node.DOCUMENT_NODE) {
    nl = ((Document) start).getDocumentElement().getChildNodes();
} else {
    nl = start.getChildNodes();
int len = nl.getLength();
Node n = null;
...
ElementgetChildElement(NodeList childs, Node parent)
Method provides getting Element objects out of a NodeList. 
Node childNode;
String parentName;
parentName = parent.getNodeName();
for (int i = 0; i < childs.getLength(); i++) {
    childNode = childs.item(i);
    if ((childNode instanceof Element) && (childNode.getParentNode().getNodeName().equals(parentName))) {
        return (Element) childNode;
return null;
ElementgetChildElement(String name, Element el)
Gets the given element's first child DOM element with the specified name. 
if (name == null || el == null)
    return null;
NodeList list = el.getChildNodes();
int size = list.getLength();
for (int i = 0; i < size; i++) {
    Node node = list.item(i);
    if (!(node instanceof Element))
        continue;
...
ElementgetChildElement(String name, Element elem)
Get a child element with a specific name. 
NodeList l = elem.getChildNodes();
for (int i = 0; i < l.getLength(); i++) {
    Node n = l.item(i);
    if (n instanceof Element && n.getNodeName().equals(name))
        return (Element) n;
return null;
ListgetChildElements(Element element, String childrenName)
Given an XML element, this method returns nested elements which are direct children of the given element - but only those that have the element-name "childrenName" (the second parameter). 
List<Element> ret = new LinkedList<Element>();
NodeList nodeList = element.getChildNodes();
for (int index = 0; index < nodeList.getLength(); ++index) {
    Node node = nodeList.item(index);
    if (node instanceof Element) {
        Element elementOfNode = (Element) node;
        if (elementOfNode.getTagName().equals(childrenName)) {
            ret.add(elementOfNode);
