JSTL cout Core Tag

by

The JSTL <c:out> Core Tag is used to display the value of an expression to the client’s browser. It works the same as of <%= %> (expression tag) or out an implicit object or expression language but the difference is that it automatically escapes XML tags while others don’t escape XML tags.

 

Syntax:

<c:out value=”value/expression” />

 

c:out tag attributes:

Attribute Description Required
value Information to output Yes
default Fallback information to output No
escapeXml True if the tag should escape special XML characters No

 

 

Example:

test.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
 
<html>
  <head>
    <title>c:out JSTL core tag example</title>
  </head>
  <body>
    <c:out value="This is a c:out JSTL core tag example."/><br/>
    Sum of 10 and 20 = <c:out value="${10+20}"/><br/><br/>
 
    <c:out value="${'<h6>This is a <c:out> escape XML test </h6>'}"/>
  </body>
</html>
