Arithmetic is not allowed on page numbers in XSL-FO.

Unless a vendor provides for you an extension for you to use, you are only able to access the current page number or a cited page number, not an algorithmically-determined page number.

The suggested solution would add the following to the bottom of the page:

3 - 1 // 3

I hope this helps (though I realize it doesn't give you what you want).

I think, you can use the '-' operator to accomplish this (shown below):

<fo:page-number/> - 1 // <fo:page-number/>

but if you need to handle page 1 in a special way, where if you do not
want to display '0 //' before 1, this simple way may be difficult to
handle this case.

I am not a good expert here, but this hint might help you get started.

I need to display the page number in the following format :
<previous_pageNumber> // <current_page Number>

For example:
On page 3, I need to display:
2 // 3
and on page 5
4 //5

We are using for 0.20.4 and xsl version 1.0
Thanks in advance,
