XSL transformation removing closing tag for empty div

I fill this div on the client side using javascript. Now, I make an
Ajax call and on the server side, I do transformation in such a way
that I get XML back as response to the Ajax call. For this, I set the
servlet response content type to be text/xml. In doing so, the output
of the transformation does not contain the closing tag  i.e it is
changed to <div class="something"/> . I would want it to keep the
closing tag. How can I achieve this?

Thanks in advance,
