Method

ElementgetFirstChild(Element root, String name)
Returns the first node that is a direct child of root with the coresponding name. 
NodeList nl = root.getChildNodes();
int size = nl.getLength();
for (int i = 0; i < size; i++) {
    Node node = nl.item(i);
    if (!(node instanceof Element))
        continue;
    Element ele = (Element) node;
    if (ele.getTagName().equals(name))
...
ElementgetFirstChild(Element tag, String childTagName)
get First Child 
NodeList nodes = tag.getElementsByTagName(childTagName);
if (nodes == null || nodes.getLength() == 0) {
    return null;
return (Element) nodes.item(0);
ElementgetFirstChild(final Element el, final String name)
Retrieves the given DOM element's first child element with the specified name. 
final NodeList nodes = el.getChildNodes();
final int len = nodes.getLength();
for (int i = 0; i < len; i++) {
    final Node node = nodes.item(i);
    if (!(node instanceof Element))
        continue;
    final Element e = (Element) node;
    if (name == null || e.getTagName().equals(name))
...
ElementgetFirstChild(final Element parent, final String childName)
Gets the first child element node with the specified tag name of a specified parent node. 
final NodeList childrenList = parent.getChildNodes();
final int childrenCount = childrenList.getLength();
for (int i = 0; i < childrenCount; ++i) {
    final Node child = childrenList.item(i);

...
ElementgetFirstChild(final Element parentElem, final String childName)
Gets the first child element with the specified name.

    return null;
return (Element) children.item(0);
NodegetFirstChildByNodeName(Node parent, String nodeName)
get First Child By Node Name 
for (Node n = parent.getFirstChild(); n != null; n = n.getNextSibling())
    if (n.getNodeName().equals(nodeName))
        return n;
