Have a follow-up question to replacing for-each-group with for-each using
muenchian grouping. - is there a way to do nested grouping using for-each
loops by this method? This is the nested loop I have (it is defined inside a
template):
<xsl:for-each-group select="//*[count(ancestor-or-self::*) = 3
group-by="@name">
<xsl:for-each-group select="current-group()/*" group-by="@name">
<xsl:value-of select="sum(current-group()/descendant::value)"/>
As you will notice, I am using the first loop's current-group() in the
second loop. I am basically trying to replace the second loop using
for-each. I tried defining an equivalent xsl:key inside the first loop but
then realized it's an error to define one inside a template.
Any help is appreciated.
Thanks,
Bhaskar

if you are using muenchian grouping, the analogue of current-group() is
key()
<xsl:for-each-group select="//*[count(ancestor-or-self::*) = 3
group-by="@name">
<xsl:value-of select="sum(current-group()/descendant::value)"/>
<xsl:key name="k" match="/*/*/*" use="@name"/>
<xsl:for-each
select="/*/*/*[generate-id()=generate-id(key('k',@name))]">
<xsl:value-of select="sum(key('k',@name)/descendant::value)"/>
