Method

ElementgetChildElement(Element parentElement, String name)
get Child Element 
Node node = parentElement.getFirstChild();
do {
    if (node.getNodeType() == Node.ELEMENT_NODE) {
        Element element = (Element) node;
        if (name.equals(element.getTagName())) {
            return element;
} while ((node = node.getNextSibling()) != null);
return null;
ElementgetChildElement(Element parentElement, String tagName)
This method returns the child element with the particular name. 
NodeList nodes = parentElement.getElementsByTagName(tagName);
if (nodes != null && nodes.getLength() != 0) {
    return (Element) nodes.item(0);
} else {
    return null;
ElementgetChildElement(Element root, String name)
getChildElement purpose. 
try {
    return getChildElement(root, name, false);
} catch (SAXException e) {
    return null;
ElementgetChildElement(Element root, String name, boolean mandatory)
getChildElement purpose. 
Node child = root.getFirstChild();
while (child != null) {
    if (child.getNodeType() == Node.ELEMENT_NODE) {
        if (name.equals(child.getNodeName())) {
            return (Element) child;
    child = child.getNextSibling();
...
ElementgetChildElement(final Element element, final String namespace, final String tagName)
Obtains the first child element with the specified name inside the specified namespace. 
final NodeList childNodes = element.getChildNodes();
final int numChildren = childNodes.getLength();
for (int i = 0; i < numChildren; i++) {
    final Node childNode = childNodes.item(i);
    if (childNode.getNodeType() != Node.ELEMENT_NODE) {
        continue;
    final Element childElement = (Element) childNode;
...
ElementgetChildElement(final Element parent, final String childName)
get Child Element 
Element child = null;
if (parent != null) {
    NodeList children = parent.getElementsByTagName(childName);
    if (children.getLength() > 0) {
        child = (Element) children.item(0);
return child;
...
ElementgetChildElement(final Element parent, final String ns, final String localName)
Get the first child element matching the local name and namespace 
List<Element> elements = getChildElements(parent);
for (Element element : elements) {
    if ((ns == null || ns.equals(element.getNamespaceURI())
            && (localName == null || localName.equals(element.getLocalName())))) {
        return element;
return null;
...
ElementgetChildElement(final Node parent, final String name)
Look for child node of given name. 
return findElementByName(parent.getFirstChild(), name);
ElementgetChildElement(final Node parentNode, final String childNodeName)
Get the first child element with the specified name from the given parent node. 
final NodeList candidates = parentNode.getChildNodes();
final int childCount = candidates.getLength();
for (int childIndex = 0; childIndex < childCount; childIndex++) {
    final Node singleChild = candidates.item(childIndex);
    if (singleChild instanceof Element && childNodeName.equals(((Element) singleChild).getTagName())) {
        return (Element) singleChild;
return null;
ElementgetChildElement(Node node)
get Child Element 
NodeList nl = node.getChildNodes();
for (int i = 0; i < nl.getLength(); i++) {
    Node n = nl.item(i);
    if (n.getNodeType() == Node.ELEMENT_NODE) {
        return (Element) n;
return null;
