Method

StringextractText(Element obj, String localName)
extract Text 
NodeList nodelist = obj.getElementsByTagNameNS("*", localName);
if (nodelist != null && nodelist.getLength() > 0) {
    Element node = (Element) nodelist.item(0);
    if (node != null) {
        String str = node.getTextContent();
        if (str != null) {
            str = str.trim();
            if (str.length() > 0)
...
StringextractTextElementValue(final Element textElement)
Trivial convenience method to extract the value of a (text) Element, coping with the possibility that text child Nodes may not have been coalesced. 
NodeList childNodes = textElement.getChildNodes();
String result;
if (childNodes.getLength() == 1) {
    result = ensureExtractTextNodeValue(childNodes.item(0));
} else {
    StringBuilder resultBuilder = new StringBuilder();
    for (int i = 0; i < childNodes.getLength(); i++) {
        resultBuilder.append(ensureExtractTextNodeValue(childNodes.item(i)));
...
InputStreamgetElementAsInputStream(Element xml)
get Element As Input Stream 
Transformer transformer = TransformerFactory.newInstance().newTransformer();
ByteArrayOutputStream out = new ByteArrayOutputStream();
StreamResult res = new StreamResult(out);
transformer.transform(new DOMSource(xml), res);
return new ByteArrayInputStream(out.toByteArray());
StringgetElementText(Element e)
get Element Text 
final StringBuilder val = new StringBuilder();
for (Node n = e.getFirstChild(); n != null; n = n.getNextSibling()) {
    if (n.getNodeType() == Node.TEXT_NODE || n.getNodeType() == Node.CDATA_SECTION_NODE) {
        val.append(n.getNodeValue());
return val.toString();
StringgetNamedElemXml(Element parent, String elementName)
get Named Elem Xml 
String val = null;
NodeList list = parent.getElementsByTagName(elementName);
if (list.getLength() > 0) {
    val = getXmlString(list.item(0));
return val;
StringgetString(Element el, String label)
get String 
NodeList l = el.getElementsByTagName(label);
if (l.getLength() < 1)
    return null;
Node n = l.item(0).getFirstChild();
return n == null ? "" : n.getNodeValue();
StringgetString(Element element)
get String 
StringBuffer buffer = new StringBuffer();
_getString(element, buffer);
return (new String(buffer));
StringgetString(Element element, String expr)
get String 
try {
    XPath xPath = XPathFactory.newInstance().newXPath();
    return xPath.evaluate(expr + "/child::text()", element, XPathConstants.STRING).toString();
} catch (Exception e) {
    return "";
StringgetString(Element element, String name, String def)
Utility to get a String attribute from the given DOM Element. 
if (!element.hasAttribute(name)) {
    return def;
return element.getAttribute(name);
StringgetString(Element root, String name)
get String 
try {
    Element e = (Element) root.getElementsByTagName(name).item(0);
    return e.getTextContent();
} catch (Exception e) {
    System.err.println("Failed to parse String for tag " + name + "!");
return "NOT SET";
