Method

intgetElementIntValue(Document document, Element parent, String string)
get Element Int Value 
return Integer.parseInt(getElementStringValue(document, parent, string));
Element[]getElements(Document document, Element parent)
get Elements 
if (parent == null) {
    return new Element[] {};
NodeList nl = parent.getChildNodes();
ArrayList al = new ArrayList();
for (int i = 0; i < nl.getLength(); i++) {
    Node n = nl.item(i);
    if (n instanceof Element) {
...
Element[]getElements(Document document, Element parent)
get Elements 
if (parent == null) {
    return new Element[] {};
NodeList nl = parent.getChildNodes();
return toElements(nl);
StringgetElementStringValue(Document document, Element parent, String element)
get Element String Value 
NodeList nl = parent.getElementsByTagName(element);
if (nl.getLength() == 0) {
    return "";
Node n = nl.item(0).getFirstChild();
if (n == null) {
    return "";
return n.getNodeValue();
StringgetElementValueByTagName(Document doc, String parentName, String eleName)
get Element Value By Tag Name 
NodeList nl = doc.getElementsByTagName(parentName);
if (null == nl) {
    return null;
Node item = nl.item(0);
return getChildElementValueByTagName((Element) item, eleName);
ElementgetFirstElement(Node parent)
Gets the first element of a Node 
Node n = parent.getFirstChild();
while (n != null && n.getNodeType() != Node.ELEMENT_NODE) {
    n = n.getNextSibling();
if (n == null) {
    return null;
return (Element) n;
...
ElementgetFirstElement(Node parent)
get First Element 
Node n = parent.getFirstChild();
while (n != null && Node.ELEMENT_NODE != n.getNodeType()) {
    n = n.getNextSibling();
if (n == null) {
    return null;
return (Element) n;
...
NodegetFirstNode(final Node parent, final String... path)
get First Node 
List<Node> nodes = getNodes(parent, path);
if (nodes == null)
    return null;
if (nodes.size() == 0)
    return null;
return nodes.get(0);
StringgetNamedElemValue(Element parent, String elementName)
get Named Elem Value 
String val = null;
NodeList list = parent.getElementsByTagName(elementName);
if (list.getLength() > 0) {
    val = ((Element) list.item(0)).getTextContent();
return val;
NodeListgetNamedNodeList(Element parent, String containerTagName)
Retrieves the DOM NodeList contained by the named element in the given parent element.
In the above example, a NodeList containing the two
elements would be returned by passing the parent element and "named-list" into the function parameters. 
NodeList nl = parent.getElementsByTagName(containerTagName);
if (nl.getLength() < 1) {
    throw new Exception("Missing named list: " + containerTagName);
return nl.item(0).getChildNodes();
