This post helps you understand how to use the <fn:escapeXml> tag in the JSTL function tags library with code example.

The fn:escapeXml function escapes any markup (HTML or XML) within the string and displays the markup as plain text by rendering tags as well.

 

JSTL <fn:escapeXml> Syntax:

${fn:escapeXml(<markup text to escape>)} 

 

JSTL <fn:escapeXml> Example:

The following code example displays escaped and non-escaped markup text.

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
	pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
    <title>fn:escapeXml Demo</title>
  </head>
  <body>
	<h1>fn:escapeXml Demo</h1>

	<c:set var="html" value="<b><i>This is html text.</i></b>" />
	<p>just html: ${html}</p>
	<p>html with escapeXml: ${fn:escapeXml(html)}</p>
  </body>
</html>

 

Output:

JSTL function fn-escapeXml
