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.
