RE: [xsl] XSL-FO page layout question

2007-04-05 07:41:59
Thanks for the suggestion. This seems to kick it in the pants and make the 
first page of the next chapter know that it is a first page. One thing it now 
does weird is that if the page before it is blank, it now prints the even 
numbered page using the odd-page layout (the running head is flush right 
instead of left like a right hand page). So I will have 3 recto-looking pages 
in a row instead of the one in the middle looking like a verso.

Anyone seen this behavior before?

Thanks,
Cindy Hunt

Cindy,

Sorry if you've been waiting -- been busy. (It happens. And for whatever 
reason, people aren't as ready to jump in on XSL-FO questions.)

Anyhow, I imagine what you want can probably be done by using attributes on 
your page-sequence elements. Check out, in particular, the 
force-page-count="even" or ="end-on-even" settings. That way each page sequence 
will start on an odd page. Then you shouldn't need the break-before behavior, 
but your pages will still be assigned their layouts more in line with your 
expectations.

Good luck,
Wendell

Thanks - this definitely gave me a good start. I did not realize I 
could put the page-sequences inside the element definition so that 
makes lots more sense to me now. This is helping but it looks like if 
one of my chapters just has a single page then the first page of the 
next chapter gets the odd-before static content rather than the 
first-page one. I know that because I stuck an "XXX" after the page 
number for the first-page to show me which model it gets. I tried 
sticking in a blank-page definition but that doesn't seem to help. Any ideas?

Cindy,

You're almost there.

Currently, you're flowing your entire content into a single 
page-sequence, as shown here:

At 09:58 AM 3/29/2007, you wrote:
<fo:page-sequence master-reference="my-sequence">
  <fo:static-content flow-name="first-before"> ... </fo:static-content>
  <!-- This code sets up running head for odd pages -->
  <fo:static-content flow-name="odd-before"> ... </fo:static-content>
  <!-- This code sets up running head for even pages -->
  <fo:static-content flow-name="even-before"> ... </fo:static-content>
  <fo:flow flow-name="xsl-region-body">
     <xsl:apply-templates select="/book/body"/>
  </fo:flow>
</fo:page-sequence>

Instead, you want each chapter to get its own page sequence. Something 
like

(where the above appeared)
      <xsl:apply-templates select="/book/body/chapter"/>

and then

<xsl:template match="chapter">
   <fo:page-sequence master-reference="my-sequence">
      ... first, your static contents ...
      then:
      <fo:flow flow-name="xsl-region-body">
        <xsl:apply-templates/>
      </fo:flow>
   </fo:page-sequence>
</xsl:template>

(with adjustments made for the actual structure of your input).

Then each chapter gets its own page sequence and thus its own first page.

You may have to adjust settings on the page-sequence-master to get 
pagination to be continuous, control where the first page appears (on 
an odd or even page), etc.

Cheers,
Wendell
