scope Scope of the variable specified in the var attribute No Page
varDom A variable that contains the parsed XML data No Page
scopeDom Scope of the variable specified in the varDom attribute No Page

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
