The books.xml file code is as follows:

<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>

The main.jsp file code is as follows:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ 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 标签</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>

The output result is as follows:

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