Hi
It turns out that a combination of checking the text length and keeping
title and body together does the trick.
I remember that Jeremias said that integer values for keep-together etc.
were kind of supported (not officially, though).
Anyway, thanks for the help!
Best regards,
Eric

Hi,
What you need here are integer values for keep-together and
keep-with-*.
Unfortunately, FOP doesn't implement this yet.
As a workaround, you can approximatively evaluate the text
length and choose to keep or not...

Yes, but the problem there is: If I do that, the long
body text will
cause an overflow, and half of my text ends up in
nirvana ;-)
Best regards,
Eric

Eric,
You should use keep-with-next on title (or
keep-with-previous on
1st para), that should do the trick.

Hi
I'm having again a problem of page
breaks and keeping
things together (I
last wrote to this list in June 07).
I have a paragraph with a title and a
body afterwards
that must be kept
together if possible. As a fix to my
last problem, I
check whether the
title and body should be kept together
always or whether
I let FOP do
the page breaks.
This means I have something like
<xsl:template match="histTxt">
<fo:block>
<xsl:choose>
<xsl:when test="string-length(.)
>
$maximumLength">
<xsl:attribute
name="keep-together">auto</xsl:attribute>
</xsl:when>
<xsl:otherwise>
<xsl:attribute
name="keep-together">always</xsl:attribute>
</xsl:otherwise>
</xsl:choose>
<xsl:apply-templates />
</fo:block>
</xsl:template>
In apply-templates, some escaped
pseudo-HTML is
converted into XSL-FO,
so at the end I have something like
<fo:block keep-together="always">
<fo:inline font-weight="bold">my
title</fo:inline>
<fo:block/>my body bla bla bla bla
bla<fo:block></fo:block>
</fo:block>
and for really long texts
<fo:block keep-together="auto">
<fo:inline font-weight="bold">my
other
title</fo:inline>
<fo:block/>Really, really long text,
much longer than
I care to type
here...<fo:block></fo:block>
</fo:block>
Most of the blocks are used for breaks,
as you can see.
However, my problem is that at some
point, the bold
title is standing on
its own, and the body appears on the
next page, like
my other title
--------------------------- page break
Really, really long text,
much longer than I care to
type here...
Not really nice! :-)
But hey, that's what orphans and widows
are for, but
after using them:
<xsl:template match="histTxt">
<fo:block>
<xsl:choose>
<xsl:when test="string-length(.)
>
$maximumLength">
<xsl:attribute
name="keep-together">auto</xsl:attribute>
<xsl:attribute
name="orphans">3</xsl:attribute>
<xsl:attribute
name="widows">3</xsl:attribute>
</xsl:when>
<xsl:otherwise>
<xsl:attribute
name="keep-together">always</xsl:attribute>
</xsl:otherwise>
</xsl:choose>
<xsl:apply-templates />
</fo:block>
</xsl:template>
The result is much worse, the titles
appear as orphans
all over the
place. Besides, as I understand the
default is 2, so
this should never
happen (?)
I'm certainly doing something wrong, but
what? I'd be
glad for any hints
:-)
Best regards,
Eric
