RE: When a page is not a page
Right.

The picture above represents a single sheet of A4 (Letter)
paper. However it also represents two pages in a book, and
if the page is folded down the dotted line it even starts to
look like a book. My problem is this; I need the page number
sequence as displayed in the picture - ie. 2 pages per page (sheet)
I have no trouble laying out the text flow correctly using
stuff like
fo:simple-page-master master-name=content
page-height={$pageheight}mm
page-width={$pagewidth}mm
margin-left={$marginleft}mm
margin-right={$marginright}mm
margin-top={$margintop}mm

fo:region-after extent=10mm/
fo:region-body margin-top=10mm
margin-bottom=10mm
column-count=2
column-gap=20mm/
/fo:simple-page-master
and I defined a static region for the page number values
using the following
fo:static-content flow-name=xsl-region-after
font-family=serif
font-size=9pt
fo:table table-layout=fixed
fo:table-column column-width=120mm/

fo:page-number/ !-- 2x + 1 --
/fo:block
/fo:table-cell
/fo:table-row
/fo:table-body
/fo:table
/fo:static-content
but I do not know how to get the fo:page-number/ to play
the game and give me more than one page number per page.
Perhaps I am wrong in my approach and there is a way of
specifying two page regions per page/sheet, but I have
not found it yet.
Any ideas?

Re: When a page is not a page
Just speculating, but have you tried putting the page-number element inside
a variable?
i.e.:
xsl:variable name=currentpagefo:page-number//xsl:variable
Then xsl:value-of select=$currentpage * 2/, etc...
I haven't tried this, but it's just what pops into my head...

RE: When a page is not a page
I believe this will not work as Wayne intends.
Page numbers will be generated sequentially starting with the
initial-page-number.
So, this might work better:
fo:page-sequence initial-page-number=0
then
xsl:variable name=currentpagefo:page-number//xsl:variable
then
Then xsl:value-of select=(2 * $currentpage) + 1/ for the left page
number
and xsl:value-of select=(2 * $currentpage) + 2/ for the right page

Re: When a page is not a page
Thanks for the tips guys. However fo:page-number/ does
not like being treated like a number, as it does not assign
to a variable numerically. This was surprising. The following
snippet
fo:block space-after=5mm text-align=justify
- fo:page-number/
- xsl:variable name=curpagefo:page-number//xsl:variable
xsl:value-of select=$curpage/
- xsl:value-of select=$curpage * 2/
- xsl:value-of select=floor($curpage) * 2/
- xsl:value-of select=column-number/
- xsl:value-of select=(2 * $curpage) + 1/
- xsl:number/
/fo:block
produces the following output
On page (sheet) 1.
- 1 - - NaN - NaN - - NaN - 1
On sheet 2.
- 2 - - NaN - NaN - - NaN - 1
i.e On sheet n.
- n - - NaN - NaN - - NaN - 1
Expected for sheet n was
- n - n - 2n - 2n - 2n? - 2n+1- 1?
Not sure why page-number behaves non-numerically. Perhaps it
is something to do with the number formatting, e.g 1 = i = a
etc. Perhaps there is a low level function that can extract
the number part from fo:page-number?
What I really need is a way of determining the number of the
current column, based on column count and page number,but
this also eludes me.

RE: When a page is not a page
Here is the thing. XSLT and XSL-FO are independent. XSL-FO has no more
special meaning to XSLT than does MathML or DocBook or SVG. XSLT understands
its own elements (including extensions of course). It understands no others.
fo:page-number/ (or as Ken Holman points out, page-number/ in the
http://www.w3.org/1999/XSL/Format namespace, since we may assign any prefix
we like, or none) is not acted on by the XSL-FO formatter to produce a
number until after XSLT is done. Period.
And note that fo:page-number/ never actually _is_ a number, and in fact
the formatter is not required to even generate a stringified page-number.
This is what the XSL Recommendation allows or does not allow you to do. If
you feel that there is a compelling use case for being able to do what you
want to do, I'd suggest writing it up and submitting it to the
[EMAIL PROTECTED] list.
Hope this clears things up.

I would choose a totally different approach: Layout your book with one page per page (:-)) and post-process the PDF (oder Postscript) with another tool. For this particular problem, there are many, very mature tools ready to use. You also gain the advantage that if you circulate the PDF or Postscript file, the user can read your document page per page and isn't irritated why the command Go to page #7 takes him to page #12.

Re: When a page is not a page
Well here's the thing I guess. I think it is a significant ommision that the FOP spec fails to supported paper that can be folded, even if this sort of paper is no longer in vogue. Still this is the case in point. Now if I were in the business of making W3C recommendations (i.e teaching my grandmother to suck eggs) I migght (at this juncture in my infant learning curve) suggest 1) deprecating [fo:]page-number/ in favour of [fo:]page-pseudo-number/ or [fo:]page-not-really-a-number-just-pretending/ 2) reworking [fo:]page-number/ to return (I don't know, maybe) a _number_. 3) introduce fo:column-number, span-number, flow-number and wing-number (which would all return _numbers_) - the latter being most useful in annotating paper planes. 4) introducing [fo:]page-number-enhanced/ which would include the more common use atrributes like linear-function-to apply_to_number=2x-1 !-- for linear transformations - default = x -- base-of-numeric-system=5 !-- for other numeber systems default = 10 -- angle-in-degrees-to rotate-number-by=90 !-- for people who read in bed -- (Notice I have correctly avoided any hint of terseness in my naming conventions.) Can anyone think of any other useful enhancements? Well I guess its back to the drawing board for now. WPE (tongue in cheek) P.S How may FOP programmers does it take to change a lightbulb? Only one, however please note that fo:light-bulb does not actually return any light, but does a neat light shade. - Original Message - From: Arved Sandstrom [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, March 30, 2002 10:47 AM Subject: RE: When a page is not a page Here is the thing. XSLT and XSL-FO are independent. XSL-FO has no more special meaning to XSLT than does MathML or DocBook or SVG. XSLT understands its own elements (including extensions of course). It understands no others. fo:page-number/ (or as Ken Holman points out, page-number/ in the http://www.w3.org/1999/XSL/Format namespace, since we may assign any prefix we like, or none) is not acted on by the XSL-FO formatter to produce a number until after XSLT is done. Period. And note that fo:page-number/ never actually _is_ a number, and in fact the formatter is not required to even generate a stringified page-number. This is what the XSL Recommendation allows or does not allow you to do. If you feel that there is a compelling use case for being able to do what you want to do, I'd suggest writing it up and submitting it to the [EMAIL PROTECTED] list. Hope this clears things up.

However fo:page-number/ does not like being treated like a number, as it does not assign to a variable numerically. This was surprising. The following snippet fo:block space-after=5mm text-align=justify - fo:page-number/ - xsl:variable name=curpagefo:page-number//xsl:variable xsl:value-of select=$curpage/ - xsl:value-of select=$curpage * 2/ - xsl:value-of select=floor($curpage) * 2/ - xsl:value-of select=column-number/ - xsl:value-of select=(2 * $curpage) + 1/ - xsl:number/ /fo:block produces the following output On page (sheet) 1. - 1 - - NaN - NaN - - NaN - 1 On sheet 2. - 2 - - NaN - NaN - - NaN - 1 i.e On sheet n. - n - - NaN - NaN - - NaN - 1 Expected for sheet n was - n - n - 2n - 2n - 2n? - 2n+1- 1? Not sure why page-number behaves non-numerically. Perhaps it is something to do with the number formatting, e.g 1 = i = a etc. Perhaps there is a low level function that can extract the number part from fo:page-number? What I really need is a way of determining the number of the current column, based on column count and page number,but this also eludes me. WPE - Original Message - From: Matthew L.
