Modifying Text by Replacement

This Example describes a method to modify the Text in a DOM document . Some of the methods which are used to modify text in the DOM Document are described below :-

Element root = doc.getDocumentElement():- allows direct access to the root of the DOM Document.

Node node = root.getFirstChild().getFirstChild():-Direct access to the subchild of the root

Text text = (Text) node.getFirstChild():-creating a text node and storing the child of node created above in it.

text.getData():-Retrives the data from the text node.

text.setData("Girish Tewari"):-Modify the text by Replacement

          text.setData("Girish Tewari");

          System.out.println("Text after Replacement is: " 

   + text.getData());

        

          }

        }
