How to print XPath Expression result in JSP?
The <x:out> tag displays the result of an XPath expression. It functions the same as <%= %> JSP syntax.
Attribute
The <x:out> tag has the following attributes −
| Attribute | Description | Required | Default |
|---|
| select | XPath expression to evaluate as a string, often using XPath variables | Yes | None |
| escapeXml | True if the tag should escape special XML characters | No | true |
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
