JAXP (Java API for XML Processing) is an interface which provides parsing of xml documents. Here the Document BuilderFactory is used to create new DOM parsers.These are some of the methods used in code given below for reading an XML document using JDOM:-

SAXBuilder builder = new SAXBuilder():-SAXBuilder is a class that bulids a JDOMDocument from file,stream,reader etc.Here we are creating SAXbuilder object which is used to Builds a JDOM document from files.

Element root = document.getRootElement():-Through this method we can have direct access to the root of the DOM document.

List row = root.getChildren("Companyname"):-List is an Interface through which we have a precise control over each element inserted in the List.Here we have created interface row which has precise control over each element inserted in the List.

public class ReadingxmlusingJdom {

  public static void main(String[] args) throws Exception {
  String data =
  "<root>" +

  Document document = builder.build(
 
new ByteArrayInputStream(data.getBytes()));
  Element root = document.getRootElement();
  List row = root.getChildren("Companyname");
  for (int i = 0; i < row.size(); i++) {
  Element Companyname = (Element) row.get(i);
 

  List column = Companyname.getChildren("Employee");
  for (int j = 0; j < column.size(); j++) {
 Element Employee = (Element) column.get(j);
 String name = Employee.getAttribute("name").getValue();
 String value = Employee.getText();
 int length = Employee.getAttribute("Age").getIntValue();

 System.out.println("Name = " + name);
 System.out.println("Profile = " + value);
