Description

The list of methods to do XML Child Node Get are organized into topic(s).

Method

NodegetChildNode(Node parentNode, String childElementName)
get Child Node 
NodeList l = parentNode.getChildNodes();
for (int i = 0; i < l.getLength(); i++) {
    Node node = l.item(i);
    if (node.getNodeName().equals(childElementName))
        return node;
return null;
NodegetChildNode(Node root, String childName)
Instead of using XPathAPI.selectSingleNode(root, "name")); use getChildNode(root, "name"); This is much quicker! 
NodeList nl = root.getChildNodes();
for (int i = 0; i < nl.getLength(); i++) {
    if (nl.item(i).getNodeName().equals(childName)) {
        return nl.item(i);
System.err.println("Childnode " + childName + " not found!");
return null;
...
NodegetChildNode(Node rootNode, String childName)
Returns the first child node of the given root node that has the given name. 
NodeList nodeList = rootNode.getChildNodes();
for (int nodeIndex = 0, nodeSize = nodeList.getLength(); nodeIndex < nodeSize; nodeIndex++) {
    Node childNode = nodeList.item(nodeIndex);
    if (childNode.getNodeName().equals(childName)) {
        return childNode;
return null;
...
NodegetChildNodeByLocalName(final Node parentNode, final String localNodeName)
Get the a specific child node from its parent node by matching the local name. 
final NodeList children = parentNode.getChildNodes();
for (int i = 0; i < children.getLength(); i++) {
    final Node child = children.item(i);
    if (child.getLocalName() != null) {
        if (child.getLocalName().equals(localNodeName)) {
            return child;
return null;
NodegetChildNodeByName(final Node xnode, final String name, final boolean caseSensitive)
Helper Method. 
NodeList list = xnode.getChildNodes();
for (int i = 0; i < list.getLength(); i++) {
    Node node = list.item(i);
    if (caseSensitive) {
        if (node.getNodeName().equals(name))
            return node;
    } else {
        if (node.getNodeName().equalsIgnoreCase(name))
...
NodegetChildNodeByName(Node element, CharSequence nodeName, boolean caseSensitive)
Helper Method. 
if (element == null)
    return null;
if (nodeName == null)
    return null;
final String name = nodeName.toString().trim();
if (name.isEmpty())
    return null;
NodeList list = element.getChildNodes();
...
NodegetChildNodeByName(Node node, String childName)
get Child Node By Name 
NodeList children = node.getChildNodes();
for (int j = 0; j < children.getLength(); j++) {
    Node child = children.item(j);
    if (child.getNodeName().equals(childName)) {
        return child;
return null;
...
NodegetChildNodeByName(Node node, String name)
get Child Node By Name 
if (node == null)
    return null;
NodeList childs = node.getChildNodes();
for (int i = 0; i < childs.getLength(); i++) {
    Node child = childs.item(i);
    if (child.getNodeName().equalsIgnoreCase(name)) {
        return child;
return null;
NodegetChildNodeByTagName(Node node, String name)
Gets a child node by the given name. 
NodeList children = node.getChildNodes();
if (children != null && children.getLength() > 0) {
    for (int i = 0; i < children.getLength(); i++) {
        Node child = children.item(i);
        if (child instanceof Element) {
            Element element = (Element) child;
            if (name.equals(element.getTagName())) {
                return element;
...
NodegetChildNodeByType(Element element, short nodeType)
get Child Node By Type 
if (element == null)
    return null;
NodeList nodes = element.getChildNodes();
if (nodes == null || nodes.getLength() < 1)
    return null;
Node node;
String data;
for (int i = 0; i < nodes.getLength(); i++) {
