How to escape characters that can be interpreted as XML markup in JSP?

JSP Java 8 Object Oriented Programming Programming

The fn:escapeXml() function escapes characters that can be interpreted as XML markup.

Syntax

The fn:escapeXml() function has the following syntax −

java.lang.String escapeXml(java.lang.String)

Example

Following is the example to explain the functionality of the fn:escapeXml() function −

<%@ taglib uri = "http://java.sun.com/jsp/jstl/core" prefix = "c" %>
<%@ taglib uri = "http://java.sun.com/jsp/jstl/functions" prefix = "fn" %>
<html>
   <head>
      <title>Using JSTL Functions</title>
   </head>
   <body>
      <c:set var = "string1" value = "This is first String."/>
      <c:set var = "string2" value = "This <abc>is second String.</abc>"/>
      <p>With escapeXml() Function:</p>
      <p>string (1) : ${fn:escapeXml(string1)}</p>
      <p>string (2) : ${fn:escapeXml(string2)}</p>
      <p>Without escapeXml() Function:</p>
      <p>string (1) : ${string1}</p>
      <p>string (2) : ${string2}</p>
   </body>
</html>

You will receive the following result −

With escapeXml() Function:
string (1) : This is first String.
string (2) : This <abc>is second String.</abc>
Without escapeXml() Function −
string (1) : This is first String.
string (2) : This is second String.
