Example

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

<%@ taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix = "x" uri = "http://java.sun.com/jsp/jstl/xml" %>
<html>
   <head>
      <title>JSTL x:out Tags</title>
   </head>
   <body>
      <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
