Example usage for javax.xml.xpath XPathFactory newInstance

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:au.edu.rmit.GalagoSearchClient.java

protected NodeList xpathGetNodeList(Document doc, String expr)
        throws XPathExpressionException, UnsupportedEncodingException {
    XPath xpath = XPathFactory.newInstance().newXPath();
    return (NodeList) xpath.compile(expr).evaluate(doc, XPathConstants.NODESET);
}
