JSTL XML <x:out> Tag
The <x:out> tag displays the result of an XPath expression, It functions similarly to the <%= %> JSP syntax.
Attribute:
The <x:out> tag has 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 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" %>

<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>
|
This would produce following result:
Books Info:
The title of the first book is: Padam History
The price of the second book: 2000
