Method

NodegetFirstTextChild(Node n)
Return the first text child node of a given node Returns null if there is no text child node 
NodeList children = n.getChildNodes();
for (int i = 0; i < children.getLength(); i++) {
    Node currentChild = children.item(i);
    if (children.item(i).getNodeType() == Node.TEXT_NODE) {
        return currentChild;
return null;
...
StringgetFirstTextChild(Node node)
get First Text Child 
NodeList nodeList = node.getChildNodes();
if (nodeList != null) {
    for (int index = 0; index < nodeList.getLength(); index++) {
        Node child = nodeList.item(index);
        if (child.getNodeType() == Node.TEXT_NODE) {
            if (child.getNodeValue() != null && child.getNodeValue().trim().length() > 0) {
                return child.getNodeValue();
return null;
ElementgetFirstVisibleChildElement(Node parent)
Finds and returns the first visible child element node. 
Node child = parent.getFirstChild();
while (child != null) {
    if (child.getNodeType() == Node.ELEMENT_NODE && !isHidden(child)) {
        return (Element) child;
    child = child.getNextSibling();
return null;
...
StringgetValueOfFirstElementChild(final Element element, final String namespace, final String localname)
get Value Of First Element Child 
Node node = getFirstElementChild(element, namespace, localname);
return (node == null) ? null : getNodeValue(node);
voidinsertBeforeFirstChild(Element object, Element attrId)
insert Before First Child 
if (object.hasChildNodes()) {
    object.insertBefore(attrId, object.getFirstChild());
} else {
    object.appendChild(attrId);
ElementreadFirstChild(Node parentNode, String nodeName)
read First Child 
if (parentNode != null) {
    NodeList children = parentNode.getChildNodes();
    for (int i = 0; i < children.getLength(); i++) {
        if (children.item(i).getNodeName().equals(nodeName))
            return (Element) children.item(i);
return null;
...
voidVectoriseFirstChildrenNodes(Node node, Vector elements)
It creates a vector with contents all the first children of a node (without the node itself) 
NodeList list = node.getChildNodes();
if (list.getLength() > 0)
    for (int i = 0; i < list.getLength(); i++)
        elements.add(list.item(i));
ElementxmlFirstChild(final Element parent, final String childName, final boolean isThrow)
Xml first child. 
final NodeList nodeList = parent.getChildNodes();
if (nodeList == null) {
    if (isThrow) {
        throw new IllegalArgumentException("nodeList == null");
    return null;
final int size = nodeList.getLength();
