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>

                Node subchild = child.getFirstChild();

                System.out.println("Subchild child of the Location is: " + subchild.getNodeName());

        

                //Returns the node immediately following this node.

                System.out.println("Node immediately following Location is :" +

                        subchild.getNextSibling().getNodeName());

            }

        }

Output of the program:-

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