JSTL - fn:split() Function


Advertisements

The fn:split() function splits a string into an array of substrings based on a delimiter string.

Syntax

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

java.lang.String[] split(java.lang.String, java.lang.String)

Example

Following is the example to explain the functionality of the fn:split() 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 = "${fn:split(string1, ' ')}" />
      <c:set var = "string3" value = "${fn:join(string2, '-')}" />

      <p>String (3) : ${string3}</p>

      <c:set var = "string4" value = "${fn:split(string3, '-')}" />
      <c:set var = "string5" value = "${fn:join(string4, ' ')}" />

      <p>String (5) : ${string5}</p>
   </body>
</html>

You will receive the following result −

String (3) : This-is-first-String.
