Hi Gerhard,
is there a workaround or xslt magic[1] or something else to get
the funcionality that was described as "formating objects for
indexing" in the working draft for xsl 1.1?
particularry the fo:index-page-citation-list was something that
would be very usefull for me.
[1] i think a lot of page-number-citation objects could do the
trick, but if i can avoid that i would prefere.
Currently that is the only way to go about it.
To mimic the example given in the XSL 1.1 WD (simplified):
Say you have <indexterm>term</indexterm> in a number of places in
your source XML, then you can define a template like:
<xsl:template match="indexterm">
<fo:wrapper id="concat(.,generate-id(.))" />
</xsl:template>
This will create the points the index will refer to.
I think you'll also need to define an xsl:key to group the indexterm
nodes by their value (maybe not necessary for XSLT 2.0, since there
you have the xsl:for-each-group functionality)
<xsl:key name="indexterm-by-term" match="indexterm" use="." />
Then, in your root template, as the very last step, you could create
a new page-sequence and do something like:
<xsl:for-each select="//indexterm[generate-id()=
generate-id(key('indexterm-by-term',.)[1])]">
<xsl:variable name="term" select="." />
<fo:block>
<xsl:value-of select="$term" />
<xsl:text> </xsl:text>
<xsl:for-each select="key('indexterm-by-term',$term)">
<fo:basic-link internal-destination="concat(.,generate-id(.))">
<fo:page-number-citation ref-id="concat(.,generate-id(.))" />
</fo:basic-link>
<xsl:if test="position()!=last()">
<xsl:text>, </xsl:text>
</xsl:if>
</xsl:for-each>
</fo:block>
</xsl:for-each>
Beware! Untested, so might need quite a bit of tweaking, but IIC,
this is the general idea.
are there any plans or a (aproximativ) timeframe when this
feature will make it into fop?
None that I'm aware of, unfortunately.
HTH!
Cheers,
Andreas
