Introduction

In this page you can find the example usage for javax.xml.xpath XPathFactory newInstance.

Prototype

public static XPathFactory newInstance()

Source Link

Document

Get a new XPathFactory instance using the default object model, #DEFAULT_OBJECT_MODEL_URI , the W3C DOM.

This method is functionally equivalent to:

 newInstance(DEFAULT_OBJECT_MODEL_URI)

Since the implementation for the W3C DOM is always available, this method will never fail.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    XPathFactory xpf = XPathFactory.newInstance();
    XPath xpath = xpf.newXPath();
    InputSource xml = new InputSource(new FileReader("input.xml"));
    Node result = (Node) xpath.evaluate("/tag1", xml, XPathConstants.NODE);
    System.out.println(result);/* ww w  .  jav  a  2  s .c o m*/
}

From source file:Main.java

    NodeList titleNodes = (NodeList) xPath.evaluate("//item/title", xml, XPathConstants.NODESET);

    for (int x = 0; x < titleNodes.getLength(); x++) {
