Re: Incrementing a Global variable

The XSLs (by Jarno and by -- Americo) are brilliant..
I was trying to solve the problem, but could'nt come
up with the solution soon..

Though the issue about incrementing the variables has
been discussed a lot on this list, I feel if there is
a feature where some sort of variable incrmenting is
possible in XSLT, it will save lot of programming
hours producing a trivial thing as generating serial
nos. I am not suggesting to deviate from the viewpoint
that XSLT should be a functional language.

But if lets say we are allowed to declare a global
variable and can increment it, it will make certain
tasks quite easy(like generating serial nos). Since
generating serial nos is a common requirement, IMHO
providing this capability in XSLT will help the user
community. Also if we can have looping constructs
which can iterate over number ranges for e.g.

for (int i=0; i < n; i++) , it will facilitate
processing loops in a diffrent way. Presently for-each
loop iterate over *node sets*. I guess these things
might be added to XSLT without deviating from the
objective to keep XSLT as a functional language.

The XSLT 2.0 spec is in draft stage. If appropriate,
these features can be thought to be added. Probably
more knowledgeable persons on this list -- M. Kay,
Dimitre, David Carlisle, Dave Pawson, Wendell, Jeni,
Jarno, Americo.. can comment on the appropriateness of
this idea ;)

Hi,

Also i have Isolated Problem Page from Actual

output

which contains multiple pdf pages. This part is
conditionaly separated from other pdf pages (

which

are
further grouped using Muenchian Method)

Could you integrage this approach to your
stylesheets?

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"

       <xsl:apply-templates select="Student[1]"/>
     </tbody>
   </table>
 </xsl:template>
 <xsl:template match="Student" name="Student">
   <xsl:param name="counter" select="1"/>
   <tr>

     <td>

     </td>
   </tr>
   <xsl:variable name="next"

         <td>
           <xsl:value-of select="$counter + 1"/>
         </td>
         <td>
           <xsl:text/>Total = <xsl:value-of

         </td>
         <td></td>
       </tr>
       <xsl:call-template name="empty">
         <xsl:with-param name="counter"
select="$counter + 2"/>
         <xsl:with-param name="left"
select="$varRowLimit - $Student_Count - 3"/>
       </xsl:call-template>
     </xsl:when>
     <xsl:when test="TOption = $next/TOption">
       <xsl:apply-templates select="$next">
