Example

{

        "student": [{ 

                       "firstName": "Mithilesh",

                        "lastName": "Kumar" 

                       }, 

                    { 

                   "firstName": "Sanjeev",

                    "lastName": "Kumar" 

                }, {

                   "firstName": "Sonu", 

                   "lastName": "Singh" 

}

] }

In the above snippet, We have stored three student records and we can write above Code in XML as below –

<?xml version="1.0" encoding="UTF-8" ?>

 <student> 

<firstName>Mithilesh</firstName>

 <lastName>Kumar</lastName> 

</student>

<student> 

<firstName>Sanjeev</firstName>

 <lastName>Kumar</lastName>

 </student>

 <student> 

<firstName>Sonu</firstName>

 <lastName>Singh</lastName> 

</student>
