Usage

From source file:Main.java

public static void main(String[] args)
        throws ParserConfigurationException, SAXException, IOException, XPathExpressionException {

    DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
    domFactory.setNamespaceAware(true);//from   ww w .  j  a  v a 2s  .c  o m
