JSTL escapeXml function is used to escape XML markup characters. EscapeXML function takes only one parameter of type String.
Syntax :
java.lang.String escapeXml(java.lang.String)
JSTL escapeXML function Example:
<%@ 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" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>JSTL EscapeXML Example</title> </head> <body> <c:set var="testString" value="This is <b>JSTL escapeXML example</b> in this JSTL function tutorial."></c:set> Without escapeXml function : ${testString} <br/> Using escapeXml function : ${fn:escapeXml(testString)} </body> </html>
Output:
Without escapeXml function : This is JSTL escapeXML example in this JSTL function tutorial.
Using escapeXml function : This is <b>JSTL escapeXML example</b> in this JSTL function tutorial.
As you can see above, fn:escapeXml() takes string parameter and returns string after escaping XML markup characters. You can see the difference between output with and without escapeXml function.
