Document

Creates a FileInputStream by using the file descriptor fdObj, which represents an existing connection to an actual file in the file system.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    XPathFactory xPathFactory = XPathFactory.newInstance();
    XPath xPath = xPathFactory.newXPath();

    InputSource doc = new InputSource(new InputStreamReader(new FileInputStream(new File("file.xml"))));

    String expression = "//Home/data";
    XPathExpression xPathExpression = xPath.compile(expression);

    NodeList elem1List = (NodeList) xPathExpression.evaluate(doc, XPathConstants.NODESET);
    xPathExpression = xPath.compile("@type");

    for (int i = 0; i < elem1List.getLength(); i++) {
        System.out.println(xPathExpression.evaluate(elem1List.item(i), XPathConstants.STRING));
    }//w w  w. j  av a2s.c om
