This Example shows you how to Load Properties from the XML file via a DOM document. JAXP (Java API for XML Processing) is an interface which provides parsing of xml documents.Javax.xml.parsers is imported to provide classes for the processing of XML Documents. Here the Document BuilderFactory is used to create new DOM parsers. Some of the methods used for reading XML from a file are described below :-
File f = new File("Document2.xml"):-Creating File from where properties are to be loaded.
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance():-Declaring DocumentBuilderFactory to create new DOm parsers.
Element root = doc.getDocumentElement():-By this method we can have direct access to the root of the DOM Document.
NodeList list = doc.getElementsByTagName("Employee"):-NodeList is an interface that provides an ordered collection of nodes.We can access nodes from the Nodelist by their index number.
NodeList nodelist = element.getElementsByTagName("name"):-This method returns a list of element with a given tagname i.e ("name").
