Java XPath scan file looking for a word

Im building an application that will taka a word from user and then scan file using XPath returning true or false depending on wheather the word was found in that file or not.

I have build following class that implements XPath, but i am either missunderstanding how it should work or there is something wrong with my code. Can anyone explain to me how to use Xpath to make full file search?

public XPath() throws IOException, SAXException, ParserConfigurationException, XPathExpressionException {
        FileInputStream fileIS = new FileInputStream("text.xml");
        DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = builderFactory.newDocumentBuilder();
        Document xmlDocument = builder.parse(fileIS);
        XPathFactory xPathfactory = XPathFactory.newInstance();
        javax.xml.xpath.XPath xPath = xPathfactory.newXPath();
        XPathExpression expr = xPath.compile("//text()[contains(.,'java')]");
        System.out.println(expr.evaluate(xmlDocument, XPathConstants.NODESET));
    }

And the xml file i am currently testing on.

<?xml version="1.0"?>

Found the solution, i was missing correct display of the found entries and as someone pointed out in comment 'java' is in arguments and i want to scan only text fields so it would be never found, after adding following code and changing the word my app will look for, application works

Object result = expr.evaluate(xmlDocument, XPathConstants.NODESET);
        NodeList nodes = (NodeList) result;
        for (int i = 0; i < nodes.getLength(); i++) {
            System.out.println(nodes.item(i).getNodeValue());
        }
