Method

StringgetText(Node node)
Return the text associated with a node, or null if no text section is present. 
if (node == null)
    return null;
Node child = findChild(node, "#text");
if (child == null)
    return null;
return child.getNodeValue();
StringgetText(Node node)
Extract the textual content from a Node. 
StringBuffer reply = new StringBuffer();
NodeList children = node.getChildNodes();
for (int i = 0; i < children.getLength(); i++) {
    Node child = children.item(i);
    if ((child instanceof CharacterData && !(child instanceof Comment))
            || child instanceof EntityReference) {
        reply.append(child.getNodeValue());
    } else if (child.getNodeType() == Node.ELEMENT_NODE) {
...
StringgetText(Node node)
get Text 
if (node == null)
    return null;
if (node instanceof Text)
    return node.getNodeValue();
NodeList children = node.getChildNodes();
for (int i = 0; i < children.getLength(); i++)
    if (children.item(i) instanceof Text)
        return children.item(i).getNodeValue();
...
StringgetTextBefore(Node node)
Get all the text DOM sibling nodes before the supplied node and concatenate them together into a single String. 
Node parent = node.getParentNode();
if (parent == null) {
    System.out.println("Cannot get text before node [" + node + "]. [" + node + "] has no parent.");
    return "";
NodeList siblings = parent.getChildNodes();
StringBuffer text = new StringBuffer();
int siblingCount = siblings.getLength();
...
StringgetTextBetween(Node node1, Node node2)
Get all the text DOM sibling nodes before the supplied node and concatenate them together into a single String. 
Node parent1 = node1.getParentNode();
if (parent1 == null) {
    System.out.println("Cannot get text between nodes [" + node1 + "] and [" + node2 + "]. [" + node1
            + "] has no parent.");
    return "";
Node parent2 = node2.getParentNode();
if (parent2 == null) {
...
voidgetTextBuffer(Node e, StringBuilder sb)
get Text Buffer 
for (Node kid = e.getFirstChild(); kid != null; kid = kid.getNextSibling()) {
    switch (kid.getNodeType()) {
    case Node.TEXT_NODE: {
        sb.append(kid.getNodeValue());
        break;
    case Node.ELEMENT_NODE: {
        getTextBuffer(kid, sb);
...
StringgetTextContent(final Node node)
get Text Content 
boolean hasTextContent = false;
final StringBuffer buffer = new StringBuffer();
final NodeList nlist = node.getChildNodes();
for (int i = 0; i < nlist.getLength(); i++) {
    final Node child = nlist.item(i);
    if (child.getNodeType() == Node.TEXT_NODE) {
        buffer.append(child.getNodeValue());
        hasTextContent = true;
...
StringgetTextContent(final Node node)
get Text Content 
switch (node.getNodeType()) {
case Node.ELEMENT_NODE:
case Node.ATTRIBUTE_NODE:
case Node.ENTITY_NODE:
case Node.ENTITY_REFERENCE_NODE:
case Node.DOCUMENT_FRAGMENT_NODE:
    return mergeTextContent(node.getChildNodes());
case Node.TEXT_NODE:
...
StringgetTextContent(final Node node, final String defaultValue)
Returns the text content of the given Node , null safe. 
if (node == null) {
    return defaultValue;
return node.getTextContent();
voidgetTextContent(final Node node, final StringBuffer sb)
Internally used by getTextContent(Node node) method. 
Node child = node.getFirstChild();
while (child != null) {
    if (child.getNodeType() == Node.TEXT_NODE) {
        sb.append(child.getNodeValue());
    } else {
        getTextContent(child, sb);
    child = child.getNextSibling();
