Description

The list of methods to do XML Node Value are organized into topic(s).

Method

StringgetNodeVal(Node node)
get Node Val 
NodeList nl = node.getChildNodes();
for (int i = 0; i < nl.getLength(); ++i) {
    if (nl.item(i).getNodeType() == Node.TEXT_NODE) {
        if (nl != null) {
            String v = ((Text) (nl.item(0))).getData();
            return v;
return null;
StringgetNodeValue(final Node iNode)
This method gets the text node of an input node. 
String value = new String();
if (iNode != null) {
    NodeList children = iNode.getChildNodes();
    int numChildren = children.getLength();
    if (children != null) {
        for (int i = 0; i < numChildren; i++) {
            if ((children.item(i).getNodeType() == Node.TEXT_NODE)
                    || (children.item(i).getNodeType() == Node.CDATA_SECTION_NODE)) {
...
StringgetNodeValue(final Node node)
get Node Value 
if (node.getNodeType() == Node.ELEMENT_NODE) {
    Node n = node.getFirstChild();
    if (n != null) {
        do {
            if (n.getNodeType() == Node.TEXT_NODE) {
                return n.getNodeValue();
        } while ((n = n.getNextSibling()) != null);
...
StringgetNodeValue(final Node node)
Retrieve a DOM node value as a string depending on its type. 
String result = "";
if (node == null) {
    return result;
switch (node.getNodeType()) {
case Node.ATTRIBUTE_NODE:
    result = node.getNodeValue();
    break;
...
StringgetNodeValue(List elements, String nodeName, String defaultValue)
Return the text value of the first child of the named node, or the specified default if the node can't be found.
For example, calling getNodeValue(el, "Mode", "whatever") on a list of elements which contains the following XML: survival should return "survival". 
if (elements != null) {
    for (Element el : elements) {
        if (el.getNodeName().equals(nodeName)) {
            if (el.getFirstChild() != null) {
                return el.getFirstChild().getTextContent();
return defaultValue;
StringgetNodeValue(Node aNode)
------------------------------------------------------------ Gets the String value of a node. 
String value = null;
if (aNode.getNodeValue() != null) {
    value = aNode.getNodeValue() != null ? aNode.getNodeValue().trim() : null;
} else {
    NodeList list = aNode.getChildNodes();
    if (list.getLength() == 1) {
        Node child = list.item(0);
        if (child != null) {
...
StringgetNodeValue(Node fatherNode, String nodeName)
Gets a node's text value given its parent node and the name of the wanted child node.
String value = null;
if (((Element) fatherNode).getElementsByTagName(nodeName) != null) {
    Node node = ((Element) fatherNode).getElementsByTagName(nodeName).item(0);
    value = node.getTextContent();
    if (value != null) {
        value = value.trim();
return value;
StringgetNodeValue(Node iNode)
This method gets the text node of an input node. 
String value = new String();
if (iNode != null) {
    NodeList children = iNode.getChildNodes();
    int numChildren = children.getLength();
    if (children != null) {
        for (int i = 0; i < numChildren; i++) {
            if ((children.item(i).getNodeType() == Node.TEXT_NODE)
                    || (children.item(i).getNodeType() == Node.CDATA_SECTION_NODE)) {
...
StringgetNodeValue(Node iNode)
This method gets the text node of an input node. 
String value = new String();
if (iNode != null) {
    NodeList children = iNode.getChildNodes();
    int numChildren = children.getLength();
    if (children != null) {
        for (int i = 0; i < numChildren; i++) {
            if ((children.item(i).getNodeType() == Node.TEXT_NODE)
                    || (children.item(i).getNodeType() == Node.CDATA_SECTION_NODE)) {
...
StringgetNodeValue(Node n)
get Node Value 
if (n == null)
    return null;
return n.getTextContent();
