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 −
