Re: [xsl] how to avoid generating an < empty element />

From: Manuel Souto Pico <manuel.souto@-------------->

ERRATA:



Where it says 'the part in red' it should say 'the term entry 5383'. 
I've just realized I can't use colours in my mails ;)



Thanks, Manuel

Hi,



I'm not experienced at all with XSLT and I've got one question 
relative to a <xsl:if test... > element which tests whether the 
element is a duplicate or not. Looking at my output you could get an 
idea of what I've managed to do:



<?xml version="1.0" encoding="UTF-8"?>

           <langSet lang="spa-es">

              <ntig>

                 <termGrp/>

              </ntig>

           </langSet>

        </termEntry>

     </body>

  </text>

</martif>



Within the <termGrp> element, the xsl:if tests whether it is the first 
time that the content of the tag <element> is processed or not. If 
it's the first one, it outputs the whole contents of the <termGrp> 
element, as in the termEntry 2107. Else, it doesn't output them (like 
in entry 5383). I think I'm using what is called Muenchian method. So 
far so good.



This would be good enough for me but I need to do something else, 
which is: if the term is not new (i.e. it has been processed and 
output before), I would like the whole entry to not appear in the 
oupput, meaning that the part in red shouldn't exist in my output. I 
can do this with some postediting of my output but I thought that, if 
possible, it would ideal to do it also with the same xsl template. Do 
you know how to do this?



This is my code, in case you want to check, and my input data (sorry 
for making the email so long):
