Thanks. I found this reference in the XSLT
Programmer's Reference, should have paid more
attention when reading :(
The reason I was using string() in key was that I am
trying to use key grouping with non-existing or empty
elements, in particular when there is no subcell
element. I realized this does not apply to this case,
since my code generates subcell elements only if there
are something.
thanks,
Xiaocun

I am not sure what is the reason for

on
this behavior. Example input XML and XSLT below.
That is the usual behaviour in XPath1 for all string
valued functions.
To get a string value from a node set (either
implicitly or explictly
using string()) you take the string value of the
first node in document
order.
You see the same effect in eg
<xsl:value-of select="cell[(_at_)column=4]/subcell"/>
which would just return teh string value of teh
first such element
whereas
<xsl:copy-of select="cell[(_at_)column=4]/subcell"/>
would return all the elements.
In this case I think the solution is just to remove
the string()
function.
I don't understand
I been using string() in xsl:key use attribute
extensively since it allows me to retrieve records
using the key value "".
as this is true whether or not you use string().

I have had several messages today that have been
somehow forwarded by
the list manager with no subject line and a return
address of
xsl-list-return-144-davidc=nag(_dot_)co(_dot_)uk(_at_)lists(_dot_)mulberrytech(_dot_)com
and the original header in the message body.,
I have added subject lines and corrected to address
etc by hand.
