Assigning generated page number to a variable fo:page-number citation

[Nedim Buke <ne...@gmail.com>]

Hi Everybody,

I need to generate index for the document. I tried to find out whether there
is extensions for doing this. Unfortunately it couldn't find any predefined
solution So I decided to write my own index generator via xsl-fop using
templates. This index consisting of any index tags inside the source
document. One index can be in any page multiple times. So I need to group
and sort page numbers where the indexentries lies. To do this I need to
assign <xsl:page-number-citation> to a varible to continue the group and
sort process. It seems it is not possible to do this in normal manner.

 Does any body has a clue on working page numbers before printing them?
Should write them in any temp location and then read them?

Thanks in advance anf best regards.

FOP v=0.94

You cannot manipulate results of fo:page-number-citation in an XSLT 
process. The reason being that XSLT and XSL-FO run as 2 separate 
independent processes with no feedback mechanism between the two.

XSL-FO 1.1 has new FOs for implementing indexes. Here is the link to the 
relevant section of the spec:

http://www.w3.org/TR/xsl/#d0e13293

Unfortunately FOP doesn't implement any of these FOs yet. I can't think 
of any alternative solutions.

Sorry,

Chris
