Writing Data in XML file Using JAVA

Writing Data in XML file Using JAVA

DOM provides many handy classes to create XML file easily. Firstly, you have to create a Document withDocumentBuilder class, define all the XML content – node, attribute with Element class. In last, use Transformer class to output the entire XML content to stream output, typically a File.

        lastName.appendChild(doc.createTextNode(lname));

        staff.appendChild(lastName);

        

        

        System.out.print("Enter Salary:");

String usalary=userinput.nextLine();

        Element salary=doc.createElement("Salary");

        salary.appendChild(doc.createTextNode(usalary));

         DOMSource source = new DOMSource(doc);

         StreamResult result =new StreamResult(new FileWriter("person.xml"));

         transformer.transform(source, result);

         System.out.println("Xml File Write Successfully....");

        

       }catch(Exception ex){

            System.out.println("Error: "+ex.getMessage());
