RE: xslt 2. index-of, nodes

No, I was wrong, it's not a Saxon bug.
You are doing
<xsl:for-each-group select="rec[mu/loc]">
but there is only one "rec" element in your data, so of course there is
only one group and only one item in that group.
I suspect you meant to do select="rec/mu[loc]", or something similar.

Subject: RE: [xsl] xslt 2. index-of, nodes
I don't think it should in your example, assuming that side
is always
'left' or 'right'. Can you put together a small example
showing it not
working? (Of course it might be a Saxon bug.)
Below. small enough xml, full stylesheet.
I couldn't shrink the stylesheet.
Worked round the concat problem using string-join
(what funny syntax!)
I expect this to produce 9 <circle> since each loc entry is
unique. It produces one, the first one in the file.
Is string join doing a 1.0 and only pulling the first node?
