RE: [xsl] CALS and keys (difficult)

["McNally, David" <David dot McNally at moodys dot com>]

I had to do something quite similar to this - here's some code:

<xsl:template match="entry">
<th>
<xsl:if test="@spanname">
	<xsl:variable name="namest"
select="ancestor::tgroup/spanspec[@spanname=current()/@spanname]/@namest"/>
	<xsl:variable name="nameend"
select="ancestor::tgroup/spanspec[@spanname=current()/@spanname]/@nameend"/>
	<xsl:variable name="colst"
select="ancestor::*[colspec/@colname=$namest]/colspec[@colname=$namest]/@col
num"/>
	<xsl:variable name="colend"
select="ancestor::*[colspec/@colname=$nameend]/colspec[@colname=$nameend]/@c
olnum"/>
	<xsl:attribute name="colspan"><xsl:value-of select="number($colend)
- number($colst) + 1"/></xsl:attribute>
</xsl:if> 
</th>
</xsl:template>

which I think is okay and correctly identifies the right colspecs for theads
and tbodys.  I don't know if it's very efficient, though, and it won't work
for entrytbl's with spanspecs.

Hope this helps,
David.
