I was not careful in the way I described this problem. Each group
consists of a single title with one or more citations. What I must
have said is that I wanted to set the Title in each group to "keep".
What I *should* have said was, I want to set the only the first
group to "keep". For the input data at the end of this email, that
would be the title "Further observations".
Is it a co-incidence that it is alphabetically the first and
positioned as first? I'm assuming because of your use of <xsl:sort>
that the alphabetical order is important in the determination of first.
All the rest would not be marked "keep".
Then I would have worded your request "the first of the sorted
population" not "the first of the group".
Clearly, I do not want (from listing 1):
<xsl:if test="position()=1">
<xsl:attribute
name="keep-with-previous">always</xsl:attribute>
</xsl:if>
It wasn't clear to me because you were grouping articles and asked
for the first of the group. I believe Martin interpreted it the same way.
I now understand you were grouping the population of articles and
need a keep on the first of the sorted population.
However, I do not know XPath well. How do I select only the first
group for marking and let the other groups pass without marking them?
<xsl:for-each-group select="...population...">
<xsl:sort .../>
<xsl:sort .../>
<xsl:sort .../>
<xsl:variable name="group-position" select="position()"/>
<xsl:for-each select="current-group()">
<fo:table-row>
<xsl:if test="position()=1 and $group-position=1">
<!--then at the very first of the sorted population-->
<xsl:attribute name="keep-with-previous">.....
I hope this helps.
