xsl:number still operates on the notion of *node
sets*. I was suggesting that if we can have a global
variable declared, can we increment its value anywhere
in the XSLT program. But this is not possible in XSLT
as this notion introduces side effects..

Can't you use <xsl:number> to get what you want?
Maybe I didn't
understand something about the problem you were
solving.

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?
