Thanks Jeni.
Compare this with what you have in your stylesheet:
<xsl:for-each-group select="rec[mu/loc]"
I need to process only rec elements with mu/loc children,
hence the match on rec?
But point taken. I guess I could mod the XML, but its working now.
[Its not a bug Mike :-)]
So in your stylesheet, you're grouping the <rec> elements rather than
the <loc> elements. It shouldn't be surprising that since there's only
one <rec> element in your XML (from the looks of it), you only get one
group!
duh! (again :-)
Try the following instead:
<xsl:for-each-group select="rec/mu/loc"
group-by="concat(@hl, '+', @side, '+', @loc)">
...
</xsl:for-each-group>
That's a worker.
The reason that concat() didn't work is that you were presumably
doing something like:
concat(mu/loc/@hl, '+', mu/loc/@side, '+', mu/loc/@loc)
In this function call, the first, third and last arguments all select
sequences containing multiple nodes
The concat() function expects its arguments
to either be empty sequences ('empty node-sets' in XPath 1.0
terminology) or singleton sequences (single values or node-sets
containing a single node in XPath 1.0 terminology).
I was close. But missed the context difference :-)
A concat() call like the one I suggested:
concat(@hl, '+', @side, '+', @loc)
is fine because the paths @hl, @side and @loc cannot select more than
one node because no two attributes on an element are named the same.
Very clear now thanks.
regards DaveP.
