The <x:out> tag has the following attributes −

Attribute	Description	Required	Default
select	XPath expression to evaluate as a string, often using XPath variables	Yes	None

Example

Let us take an example which will cover the tags (a) <x:out>, (b) <x:parse>.

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

               <name>Padam History</name>
               <author>ZARA</author>
               <price>100</price>

            <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
