Method

NodefindNode(Node node, String attr, String value)
Returns the first node where attr equals value. 
String tmp = (node instanceof Element) ? ((Element) node).getAttribute(attr) : null;
if (tmp != null && tmp.equals(value)) {
    return node;
node = node.getFirstChild();
while (node != null) {
    Node result = findNode(node, attr, value);
    if (result != null) {
...
ElementfindNodeByAttributeValue(NodeList nodeList, String attributeName, String attributeValue)
find Node By Attribute Value 
int len = nodeList.getLength();
String tmp;
Element property;
for (int i = 0; i < len; i++) {
    property = (Element) nodeList.item(i);
    tmp = property.getAttribute(attributeName);
    if (attributeValue.equals(tmp)) {
        return property;
...
ElementgetElementByAttribute(Element root, String tagname, String attribute, String att_value)
get Element By Attribute 
NodeList nl = root.getElementsByTagName(tagname);
for (int i = 0; i < nl.getLength(); i++) {
    Element elem = (Element) nl.item(i);
    if (elem.getAttribute(attribute).equals(att_value)) {
        return elem;
return null;
...
ElementgetElementByAttribute(String attr, String value, Element root)
get Element By Attribute 
Element found = null;
if (root.hasAttribute(attr) && root.getAttribute(attr).equals(value)) {
    return root;
NodeList nl = root.getChildNodes();
for (int i = nl.getLength() - 1; i >= 0; i--) {
    if (nl.item(i).getNodeType() == Node.ELEMENT_NODE) {
        found = getElementByAttribute(attr, value, (Element) nl.item(i));
...
ElementgetElementByAttributeValue(List elements, String attName, String attValue)
get Element By Attribute Value 
for (Element e : elements) {
    String s = e.getAttribute(attName);
    if (attValue.equals(s))
        return e;
return null;
ElementgetElementByAttributeValue(Node start, String tagName, String attrName, String attrValue)
equivalent to the XPath expression './/tagName[@attrName='attrValue']' 
NodeList nl = ((Element) start).getElementsByTagName(tagName);
int l = nl.getLength();
if (l == 0) {
    return null;
Element e = null;
String compareValue = null;
for (int i = 0; i < l; i++) {

intgetElementIntAttribute(Element e, String whichAttribute)
get Element Int Attribute 
int val = -1;
String number = e.getAttribute(whichAttribute);
if (number != null) {
    try {
        val = Integer.parseInt(number.trim());
    } catch (NumberFormatException ex) {
        val = -1;

LinkedListgetElementsWithAttribute(Element element, String attribute)
Get the elements descendant having the specified attribute name. 
LinkedList elements = new LinkedList();
if (element.hasAttribute(attribute)) {
    elements.add(element);
NodeList childs = element.getChildNodes();
for (int i = 0; i < childs.getLength(); i++) {
    Node node = childs.item(i);
    if (Node.ELEMENT_NODE == node.getNodeType()) {
...
voidgetElementsWithAttribute(Element element, String namespaceURI, String localName, String value, Collection elements)
get Elements With Attribute 
if (element.hasAttributeNS(namespaceURI, localName)) {
    String attr = element.getAttributeNS(namespaceURI, localName);
    if (attr.equals(value))
        elements.add(element);
NodeList childs = element.getChildNodes();
for (int i = 0; i < childs.getLength(); i++) {
    Node node = childs.item(i);
...
ListgetElementsWithAttributeEquals(Element root, String attribute, String value)
Retrieve the list of the elements which have an attribute equal to the given value. 
List<Element> list = new ArrayList<Element>();
getElementsWithAttributeEquals(root, attribute, value, list);
return list;
