Inserting a New Entry in a List


This Example shows you how to Insert a new Entry in a list  in a DOM document. 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. Here we use "javax.xml.transform" package that defines the generic APIs to process transformation instructions, also performs a transformation from source to result. There are some of the methods used in code given below for Inserting a new Entry in List:-

Element person = doc.createElement("Roseindia"):-This method creates an Element Node. Here "Roseindia" is the String that specifies the name of the element node.

person.appendChild(Node):-This method adds a node after the last child node of the specified node.

Text nametextNode = doc.createTextNode(name):-This method creates a Text Node.

root.insertBefore(person, firstNode):-This method insert person node before firstNode.

TransformerFactory factory = TransformerFactory.newInstance():-TransformerFactory is a class that is used to create Transformer objects. A TransformerFactory instance can be used to create Transformer and Templates objects.

transformer.setOutputProperty(OutputKeys.INDENT, "yes"):-This method set an output property for the transformation. Here OutputKeys.INDENT is an output property name and "yes" is the value of the output property.

transformer.transform(source, result):-This function organize data according to a style sheet as we are retrieving it from the File.

Xml code for the program generated is:-

<?xml version="1.0" encoding="UTF-8"?>
  <Employeename>Girish Tewari</Employeename>

  StreamResult result = new StreamResult(sw);
  DOMSource source = new DOMSource(doc);
  transformer.transform(source, result);
  String xmlString = sw.toString();



Output of the program:-

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
