∟c:forTokens Action Tag

This section describes the c:forTokens action tag in the JSTL Core library. c:forTokens allows you to specify a section of JSP code that will be processed repeatedly by iterating through a list of tokens.

The <c:forTokens> action tag allows you to specify a section of JSP code that will be processed repeatedly by iterating through a list of tokens. Syntax of the <c:forTokens> action tag is:

<c:forTokens var="name" items="token_list" delims="expression"
   begin="expression" end="expression" step="expression">
   body
</c:forTokens>

Note that:

items="token_list" specifies a string of tokens to iterate over.
delims="expression" specifies the delimiter used in "token_list" to separate tokens.
var="name" specifies an EL variable that stores the selected token of the current iteration.
begin="expression" specifies the index where the iteration starts.
end="expression" specifies the index where the ends starts.
step="expression" specifies the step size that will be used to increment the index at each iteration.

In other words, the string specified by the "items" attribute will be tokenized with the delimiter specified by the "delims" attribute. Then resulting tokens will be iterated. At each iteration, the current token will assign to a named variable specified in the "var" attribute, and body will be processed.

If the "begin", "end" or "step" attribute is specified, it will be used to restrict the beginning element, the ending element, or the step size of the iteration.
