Method

StringgetElementValue(Element elem, String path)
Returns the text value of the named descendent. 
Element child = getElement(elem, path);
if (child == null)
    return "";
String ret = "";
NodeList nl = child.getChildNodes();
for (int i = 0, len = nl.getLength(); i < len; i++) {
    Node node = nl.item(i);
    if (node.getNodeType() == Node.TEXT_NODE)
...
StringgetElementValue(Element element)
get Element Value 
if (element != null) {
    NodeList nodes = element.getChildNodes();
    if ((nodes != null) && (nodes.getLength() > 0)) {
        for (int i = 0; i < nodes.getLength(); i++) {
            Node node = nodes.item(i);
            if ((node instanceof Text)) {
                return ((Text) node).getData();
return null;
StringgetElementValue(Element element)
Returns the node value of the element's first child if there is any, otherwise null. 
Node child = element.getFirstChild();
if (child != null) {
    return child.getNodeValue();
return null;
StringgetElementValue(Element element)
Check if the element contains just a text/cdata, in which case return that value. 
if (element.getAttributes().getLength() > 0) {
    return null;
NodeList children = element.getChildNodes();
String value = null;
int nbrChildren = children.getLength();
for (int i = 0; i < nbrChildren; i++) {
    Node child = children.item(i);
...
StringgetElementValue(Element element)
Get the value of the specified element 
NodeList nl = element.getChildNodes();
for (int i = 0; i < nl.getLength(); i++) {
    if (nl.item(i).getNodeType() == Node.TEXT_NODE) {
        return element.getFirstChild().getNodeValue();
return null;
StringgetElementValue(Element element)
Gets the value of an element. 
if (element == null) {
    return null;
StringBuffer sb = new StringBuffer(1000);
NodeList nl = element.getChildNodes();
Node child = null;
int length = nl.getLength();
for (int i = 0; i < length; i++) {
...
StringgetElementValue(Element element, String elementName)
This method return role name from xml file. 
String roleName = "";
NodeList elementList = element.getElementsByTagName(elementName);
Element ele = (Element) elementList.item(0);
NodeList valueNodeList = ele.getChildNodes();
Node node = ((Node) valueNodeList.item(0));
if (node != null) {
    roleName = node.getNodeValue();
return roleName;
StringgetElementValue(Element element, String name)
Gets the value of a named child element. 
return ((Element) element.getElementsByTagName(name).item(0)).getFirstChild().getNodeValue();
StringgetElementValue(Element element, String tag)
get Element Value 
Element by = getElement(element, tag);
if (!(by == null)) {
    return by.getFirstChild().getNodeValue();
return null;
StringgetElementValue(Element element, String tagName)
get Element Value 
return getElementValue(element, tagName, 0);
