docbook: Thread: keep-with-next

Hello David or anybody else who knows about this,

A while ago I was told to use this for keeping together Q&A when printing:

  <xsl:template match="instructions">
    <fo:block keep-with-next="always">Instructions</fo:block>
    <fo:block><xsl:apply-templates/></fo:block>

  </xsl:template>


I'm really not a hero in this.  Where do I configure this?  And can it
also work for keeping together lists?

Thansk for any hints,

Tille.

Tille,

The example above is useful if you are writing your own XSL style sheet
or wanting to modify and existing one.  But maybe this is not what you
are trying to do.  Is your original document is in DocBook XML and are
you using the DocBook XSL stylesheets to transform it?  If so, what are
you transforming it into?  Also, what tool are you using to do the
transformation?

Dave

Hello Dave,

I am writing in DocBook XML, and using xsltproc to convert to FO, then I
use fop to convert to PDF.  I was trying to modify the lists.xsl that
comes with the DocBook XSL stylesheets, with no result.  I've modified the
stylesheets now to allow hard pagebreaks, but that is not at all handy, of
course.  I've changed from qandaset to orderedlists because it is more
handy for the numbering (multiple answers per question).  This is a sample
source:

<article>
<orderedlist>
	<listitem><para>Question 1</para>
		<orderedlist>
			<listitem><para>answer 1</para></listitem>
			<listitem><para>answer 2</para></listitem>
			<listitem><para>answer 3</para></listitem>
			<listitem><para>answer 4</para></listitem>
		</orderedlist>
	</listitem>

        <listitem><para>Question 2</para>
                <orderedlist>
                        <listitem><para>answer 1</para></listitem>
                        <listitem><para>answer 2</para></listitem>
                        <listitem><para>answer 3</para></listitem>
                        <listitem><para>answer 4</para></listitem>
                </orderedlist>
        </listitem>


</orderedlist>

What I want to obtain is that the questions are kept together with their
answers automatically.  So no page breaks after a question, no pagebreaks
in the middle of an answerlist.

Thanks for your time,

Tille.

In my experience FOP has not implemented all of the page break controls
used by XSL-FO stylesheets.  Watch for errors and warnings when FOP runs.
I think there will be several similar to "property 'break-before' not
implemented yet".  That means that the DocBook XSL stylesheet has asked
for no page break, but FOP can't deal with it.  Let me know if you see
the errors.
