White space problem

Hi all
I am using struts with jstl. I have a problem that is a bit annoying.
In the navigation jsp on one of my sites I have 2 nested c:forEach tags that have c:if tags inside them. If a bean element meets the c:if condition
it gets c:out to the page, if not the loop skips over it until all the outer c:forEach beans have been looped.

The problem is however when the c:if condition is not met a white line is written out by the c:forEach (ie one white line for each iteration regardless of the c:if condition). This ends up with a MASS of white space on the page. Is there anyway to stop the c:forEach writing out the white space ?

You can use the <string:trim> tag from jakarta taglibs

Yes, same as with any tag or scriptlet.

<c:forEach ....
  ><c:if ...>

   </c:if
></c:forEach>



Of course, you could always use a servlet filter and replace all "\n+" with
"/n".
