@Genzer Hi, I have tried to read the file by using BufferedReader but I don't know how to add the required elements into it. I tried it by seeing this example- stackoverflow.com/questions/8563294/… — RahulD

Java already has a parser, called DOM that could help you. You could use something like this:

File theXML = new File("C:\\path\\to\\file.xml");
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(theXML);
doc.getDocumentElement().normalize();

If you've ever used JavaScript DOM, you should know what to do now, use doc.getElementsByTagName or the like. If you don't, check out the oracle tutorial

You can use this way to read your html (into a String). After that, your task is actualy to do some String splitting, replacing and inserting, and, finally, writing it all to the html file on your HDD using a simiar method as you read it from the HDD.
