variable containing the page number

Hi

I want to put the value of fo:page-number into a variable because i have 
different static-content depending on what page number it is. I want to 
use this variable to check what page number it is. Do anyone know how to 
do this?

regards

Eivind Andreassen.

Variables exist in the XSLT process, page-numbers exist only in 
XSL-FO->PDF generation. These are separate processes between which there 
is no state sharing.

So what you asked for is not possible. Fortunately XSL-FO provides 
another means to achieve different static-content on different pages.

Here is a snipper from the franklin_alt.fo file which is an example 
shipped with FOP:

     <!-- layout for the first page -->
     <fo:simple-page-master master-name="right"
         page-height="21.7cm"
         page-width="16cm"
         margin-top="1cm"
         margin-bottom="1cm"
         margin-left="3.5cm"
         margin-right="1.5cm">
         <fo:region-body margin-top="2cm" margin-bottom="2cm"/>
         <fo:region-before extent="2cm"/>
         <fo:region-after extent="2cm"/>
     </fo:simple-page-master>

       <fo:simple-page-master master-name="left"
             page-height="21.7cm"
             page-width="16cm"
             margin-top="1cm"
             margin-bottom="1cm"
             margin-left="1.5cm"
             margin-right="3.5cm">
       <fo:region-body margin-top="2cm" margin-bottom="2cm"/>
       <fo:region-before extent="2cm"/>
       <fo:region-after extent="2cm"/>
     </fo:simple-page-master>

   <fo:page-sequence-master master-name="alternating">
     <fo:repeatable-page-master-alternatives maximum-repeats="no-limit">
       <fo:conditional-page-master-reference master-reference="right"
         odd-or-even="odd" />
       <fo:conditional-page-master-reference master-reference="left"
         odd-or-even="even" />
     </fo:repeatable-page-master-alternatives>
   </fo:page-sequence-master>

Hopefully it gives you the idea.

Chris

So you want a different static-content on the last front side?

I don't think this is possible unless you know the exact page number :(

What needs to change in the static content for the last front side? If 
its just different text then you can achieve this using markers.

yes.

mmh i thought/think the same :-)

it's a completly different page with borders, headers, footers i think
this will be a little hard with markers.

anyway to achieve page numbers divisible by four i evaluate the areatree
with an xslt in a first run. just thougt their could be a cool hack out
there :-)

cheers,
gregor

Hi,

this thread has arised an interesting point for my project ... 

[...]

do you have any idea to realize this a little more complex?

what i need is: the maximun repeats in dependency on the total number of
pages. 

i'm creating booklets with 4,8,12,16 pages and every two last pages has
to be single pages.   

something like:

<fo:repeatable-page-master-alternatives maximum-repeats="pages - 2">
[...] </...
<fo:single-page-master-reference master-reference="before-last"/>
<fo:single-page-master-reference master-reference="last"/>

i know how to set the last page in a page repeat loop, but the pages
before last?

thanks!

gregor
