Method

StringgetFirstChildTextValue(Element parent, String childName)
get First Child Text Value 
NodeList children = parent.getChildNodes();
for (int i = 0; i < children.getLength(); i++) {
    Node child = children.item(i);
    if (child instanceof Element) {
        Element elem = (Element) child;
        if (childName.equals(elem.getNodeName())) {
            return getOrCreateFirstTextChild(elem).getTextContent();
return null;
ElementgetFirstChildWithTagName(Element parent, String tagName)
get First Child With Tag Name 
final NodeList elements = parent.getElementsByTagName(tagName);
return (elements.getLength() > 0) ? (Element) (elements.item(0)) : null;
ElementgetFirstChildWithTagName(Node data, String tagName)
The function getFirstChildWithTagName() returns the first child node from a node, identified by its node name. 
for (Node element = data.getFirstChild(); element != null; element = element.getNextSibling()) {
    if (!(element instanceof Element)) {
        continue;
    if (element.getNodeName().equals(tagName)) {
        return (Element) element;
throw new NoSuchElementException(tagName);
ElementgetFirstElement(Element element, String childName)
get First Element 
NodeList children = element.getChildNodes();
for (int i = 0; i < children.getLength(); i++) {
    Node child = children.item(i);
    if (child instanceof Element && ((Element) child).getTagName().equals(childName)) {
        return (Element) child;
return null;
...
ElementgetFirstElementChild(Element aElement)
Gets the first DOM Element Node of the aElement DOM Element. 
NodeList children = aElement.getChildNodes();
