Method

StringgetValue(final String expression, final String xml)
Evaluates the XPath expression against the xml and returns the selected value. 
final InputSource source = new InputSource(new StringReader(xml));
final XPathFactory factory = XPathFactory.newInstance();
final XPath xpath = factory.newXPath();
return xpath.evaluate(expression, source);
StringgetValueByPath(Node node, String path)
get Value By Path 
XPathExpression expr = compile(path);
try {
    return expr.evaluate(node);
} catch (Exception e) {
    throw new RuntimeException(e);
StringgetValueByXpath(Node doc, String xquery)
get Value By Xpath 
try {
    XPathFactory factory = XPathFactory.newInstance();
    XPath xpath = factory.newXPath();
    XPathExpression expression = xpath.compile(xquery);
    String result = (String) expression.evaluate(doc, XPathConstants.STRING);
    return result;
} catch (Exception e) {
return null;
StringgetValueFromXML(final String inputXML, final String xPathQuery, final int index)
get Value From XML 
return getValueFromXML(inputXML, xPathQuery, index, null);
ListgetValues(final String expression, final String xml)
Evaluates the XPath expression against the xml and returns the selected values. 
final NodeList xpathResults = getNodes(expression, xml);
final List<String> results = new ArrayList<String>(xpathResults.getLength());
for (int i = 0; i < xpathResults.getLength(); i++) {
    results.add(xpathResults.item(i).getNodeValue());
return results;
XPathgetX_PATH()
get PATH 
if (X_PATH == null) {
    X_PATH = XPathFactory.newInstance().newXPath();
return X_PATH;
NodexGetNode(Node targetNode, String expression)
Uses the passed XPath expression to locate a single node in the passed element. 
Node node = null;
XPath xpath = null;
try {
    xpath = XPathFactory.newInstance().newXPath();
    XPathExpression xpathExpression = xpath.compile(expression);
    node = (Node) xpathExpression.evaluate(targetNode, NODE);
