The <x:parse> tag is used to parse XML data in attributes or tag bodies.
<x:parse var="<string>" varDom="<string>" scope="<string>" scopeDom="<string>" doc="<string>" systemId="<string>" filter="<string>"/>
The <x:parse> tag has the following attributes:
| Attribute | Description | Whether necessary | Default value |
|---|---|---|---|
| var | Variables containing parsed XML data | No | None |
| xml | The text content of the document to be parsed (String or Reader) | No | Body |
| systemId | System identifier URI, used to parse the document | No | None |
| filter | The filter applied to the source document | No | None |
| doc | The XML document to be parsed | No | Page |
| scope | The scope of the var attribute | No | Page |
| varDom | Variables containing parsed XML data | No | Page |
| scopeDom | The scope of the varDom attribute | No | Page |
The following examples show us how to parse an XML document:
The code of the books.xml file 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"/html; charset=UTF-8-8"
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 Tag</title>
</head>
<body>
<h2>Books Info:</h2>
<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 running result is as follows:
BOOKS INFO: The title of the first book is:Padam History The price of the second book: 2000
