Replacing a Text Node with a New CDATA Section Node

This Example describes a method to replace a Text node with new CDATASection Node in a DOM document. Methods which are used for replacement of the text node in the DOM Document are described below :-

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

Element place = (Element) root.getFirstChild():-access the first child of the root.

Element directions = (Element) place.getLastChild():-access the last child of the node place and stores in the new node direction.

CDATASection dirdata = doc.createCDATASection(dirtext):- creates a cdata node with text in it.

directions.replaceChild(dirdata,directions.getFirstChild()):-replaces a child node direction with CDATASection node.
