In this section, you will learn about Locate a node by using method Sibling .

Locating a Node by Using Siblings

     

This Example describes a method to Locate a node by using method Sibling .Methods which are used for locating a node in a DOM tree are described below :-

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

Node child = root.getFirstChild():-gets the first child of the root.

subchild.getNextSibling().getNodeName():-method gets the next sibling of this node & gets its name also.

Xml code for the program generated is:-

<?xml version="1.0" encoding="UTF-8"?> <Company>   <Location>   <Companyname>Roseindia .Net</Companyname>   <Employee>Girish Tewari</Employee>   </Location> </Company>

UsingSibling.java:-

Output of the program:-

First child of the root is: Location Subchild child of the Location is: Companyname Node immediately following Location is :Employee
