Method

StringgetNodeValue(Element node)
This will get the text value of an element. 
String retval = "";
NodeList children = node.getChildNodes();
for (int i = 0; i < children.getLength(); i++) {
    Node next = children.item(i);
    if (next instanceof Text) {
        retval = next.getNodeValue();
return retval;
StringgetNodeValue(Element node)
This will get the text value of an element. 
StringBuilder sb = new StringBuilder();
NodeList children = node.getChildNodes();
int numNodes = children.getLength();
for (int i = 0; i < numNodes; i++) {
    Node next = children.item(i);
    if (next instanceof Text) {
        sb.append(next.getNodeValue());
return sb.toString();
StringgetText(Element parentNode)
Extracts the String content of a TXT element. 
Text text = getTextNode(parentNode);
return (text == null) ? null : text.getData();
TextgetTextNode(Element element)
Returns element's TEXT child node (if it has one). 
return (Text) getChildByType(element, Node.TEXT_NODE);
StringgetTextTrim(Element elto)
get Text Trim 
StringBuffer content = new StringBuffer();
NodeList contentE = elto.getChildNodes();
int i = 0;
while (contentE.item(i) != null
        && (contentE.item(i).getNodeType() == Node.TEXT_NODE || contentE
                .item(i).getNodeType() == Node.CDATA_SECTION_NODE)) {
