Getting next Tag in the XML File


This Example shows you how to get the next Tag from the XML File. 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.There are some of the methods used in code given below for Modifying a DOM Tree:-

XMLInputFactory Factory = XMLInputFactory.newInstance():-By this method we create a new instance of the factory.

XMLStreamReader reader = Factory.createXMLStreamReader(new FileInputStream(file)):-Creates a new StreamReader which allows forward, read-only access to XML.

eventTypeID = reader.nextTag():-This method is used to skip events i.e COMMENT and PROCESSING_INSTRUCTION until a START_ELEMENT or END_ELEMENT is reached.

eventTypeID = using this method we get the next parsing event.


Xml code for the program generated is:-

<?xml version="1.0" encoding="UTF-8"?>
<!-- Information About Employees -->
  <Employee Id="Rose-2345">
  <name>Girish Tewari</name>
 <Doj>May 2008</Doj>
  <!-- Information about other  Employee -->  
  <Employee Id="Rose-2346">
 <name>Mahendra Singh</name>
  <Doj>May 2008</Doj>

  XMLInputFactory Factory = 

  XMLStreamReader reader = 
new FileInputStream(file));
  //Cursor is at the root of the xmlfile.
  int eventTypeID = reader.nextTag();
  eventTypeID = reader.nextTag();
  eventTypeID =;
  eventTypeID =;
  eventTypeID =;
  System.out.println("Text of the  first Node is:  " 
  + reader.getText());

  eventTypeID = reader.nextTag();
  eventTypeID =;
  eventTypeID =;
  eventTypeID =;
  System.out.println("Text of the Second Node is:  " 
  + reader.getText());


Output of the program:-

Text of the  first Node is:  Newstrack

Text of the Second Node is:  Rohini
