Method

NodeevaluateXPathExpressionAndReturnNode(String expression, Node node)
Evaluates a XPath expression from a XML node, returning a Node object 
try {
    return (Node) xPath.get().evaluate(expression, node, XPathConstants.NODE);
} catch (XPathExpressionException e) {
    return null;
NodeListevaluateXPathExpressionAndReturnNodeList(String expression, Node node)
Evaluates a XPath expression from a XML node, returning a NodeList. 
try {
    return (NodeList) getXPath().get().evaluate(expression, node, XPathConstants.NODESET);
} catch (XPathExpressionException e) {
    return null;
NodeListevaluateXPathQuery(Document doc, NamespaceContext context, String xPathQuery)
evaluate X Path Query 
XPathExpression expr = createXPathExpression(context, xPathQuery);
return (NodeList) expr.evaluate(doc, XPathConstants.NODESET);
ObjectevalXPath(Node d, String expr, QName returnType)
Gets the object at the given XPath in the given XML node. 
return XPathFactory.newInstance().newXPath().compile(expr).evaluate(d, returnType);
ListevalXPath(Node node, String xPath)
eval X Path 
synchronized (xpath) {
    try {
        NodeList nodes = (NodeList) xpath.evaluate(xPath, node, XPathConstants.NODESET);
        int size = nodes.getLength();
        ArrayList<Node> list = new ArrayList<Node>(size);
        for (int i = 0; i < size; i++)
            list.add(nodes.item(i));
        return list;
...
TevalXPath(String expression, Object item, Class type)
Evaluates an XPath returning null if not found. 
Object val;
if (type == String.class)
    val = evalXPath(expression, item, XPathConstants.STRING);
else if (type == CharSequence.class)
    val = evalXPath(expression, item, XPathConstants.STRING);
else if (type == Boolean.class)

NodeListevalXpath(String xpath, Object item)
eval Xpath 
XPath xp = XPathFactory.newInstance().newXPath();
XPathExpression expr = xp.compile(xpath);
return (NodeList) expr.evaluate(item, XPathConstants.NODESET);
StringevalXPathAsString(Object item, String xpath, XPathFactory factory)
eval X Path As String 
XPath path = factory.newXPath();
XPathExpression expr = path.compile(xpath);
return (String) expr.evaluate(item, XPathConstants.STRING);
ListevalXPathAsStringList(Object item, String xpath, XPathFactory factory, boolean includeDuplicates)
eval X Path As String List 
NodeList nl = evalXPathAsNodeList(item, xpath, factory);
List<String> result = new ArrayList<String>(nl.getLength());
for (int i = 0; i < nl.getLength(); i++) {
    String text = nl.item(i).getTextContent();
    if (includeDuplicates || !result.contains(text)) {
        result.add(text);
return result;
