<%@ taglib prefix = "x" uri = "http://java.sun.com/jsp/jstl/xml" %>

   <head>
      <title>JSTL x:out Tags</title>

      <h3>Books Info:</h3>

      <c:set var = "xmltext">
         <books>
            <book>
               <name>Padam History</name>
               <author>ZARA</author>
               <price>100</price>
            </book>
            
            <book>
               <name>Great Mistry</name>
               <author>NUHA</author>
               <price>2000</price>
            </book>
         </books>
      </c:set>

      <x:parse xml = "${xmltext}" var = "output"/>
      <b>The title of the first book is</b>: 
      <x:out select = "$output/books/book[1]/name" />
      <br>
      
      <b>The price of the second book</b>: 
      <x:out select = "$output/books/book[2]/price" />
   
   </body>
</html>

The above code will produce the following result −

Books Info:

The title of the first book is: Padam History The price of the second book: 2000
