Thanks Michael.
The important distinction you have made, and that I had missed, is between "an
element that exists" and "an element that exists and is not null".
I've fitted this into my implementation (not your XPath 2) and can now see it
working.
Where I previously had :
<test heading="{preceding-sibling::node()[column[1]][1]/column[1]}"
type="absent" value="{column[3]}" />
I now have :
<test heading="{preceding-sibling::node()[column[1] != ''][1]/column[1]}"
type="absent" value="{column[3]}" />
And that works.
However .....
Now I come to incorporate what I've learnt into my real problem I find that I
asked the wrong question....
Another will be along in a moment, under a new Subject.
Appreciatively,
Richard.

Hi Richard,
Your predicate just checks whether any of the preceding-sibling rows have a
first column child, you also have to check whether it is empty or not. How
about this, if you can use XPath 2:
<xsl:template match="row">
<xsl:variable name="heading" select="column[@column eq '1']" />
<item row="{@row}" name="{
if ($heading != '')
then $heading
else preceding-sibling::row[column[@column eq '1'] !=
''][1]/column[@column eq '1']
}" value="{column[@column eq '3']}" />
</xsl:template>
You see I also used the @column attribute to locate the correct cell but that
might be unnecessary.
Of course it would be even better to create a function like
my:GetCurrentHeading() to encapsulate the if-then-else stuff.
HTH,
- Michael
