Example

The following example shows how parse can be used to read the external XML file −

We have seen how we can parse XML from the body of the given document. Let us now put following content in the books.xml file −

<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>

Now try the following main.jsp, keeping in the same directory −

<%@ 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:parse Tags</title>
   </head>

   <body>
      <h3>Books Info:</h3>
      <c:import var = "bookInfo" url = "http://localhost:8080/books.xml"/>

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

   </body>
</html>

Access the above JSP using http://localhost:8080/main.jsp, the following result will be displayed −

Books Info:

The title of the first book is:Padam History

The price of the second book: 2000
