Regenerating XML Document
Previous Home Next

In this page of tutorials, we will be learn to get the elements and its value using DOM APIs. In this program parses a xml file and regenerates it at the console using the DOM APIs. In This program we are take a XML file and check it is available or not . If file is exist then it creates DocumentBuilderFactory. This object creates a DocumentBuilder which parses the XML document using the parser() method. It invokes the DocumentBuilder object and creates a Document object. Through this object you create DOM tree nodes by using the getDocumentElement() method and passes it to the DOMSource(). The DOMSource constructor creates a new input source with a DOM node. And the destination source uses the StreamResult() constructor.
