Hi Michael, At the moment, Brandon's solution appears to be working. If after examining the output from my full data set I discover it has problems, I'll give your solution a try. By the way, your code contains XPath expressions I have never seen, so I will look those up in order to broaden my XPath repertoire.

Thanks for your help,
Mark

My question now is: how can I change this stylesheet so that for the listed input, no <FormatButtons> in the output contains more than one copy of a <Format> with the same attribute name and value? That is, where the current output is, for example:
<FormatPage souvenir-sheet="365">
 <FormatButtons>
   <Formats se-tenant="365"/>
   <Formats se-tenant="365"/>
   <Formats coupon="367"/>
   <Formats coupon="368"/>
 </FormatButtons>
</FormatPage>

Mark,

If a node in your sample is a duplicate of another node can be retrieved from the attribute names and their values. So IMO the grouping key could be a serialization of them. In other words, we look at the source as if we were a text processor, like this:

<xsl:template match="FormatButtons">
 <xsl:copy>
   <xsl:for-each-group select="Formats"
       group-by="string-join(
         for $i in 1 to count(@*)
           return concat(name(@*[$i]), '=', @*[$i]), ' ')">
     <xsl:apply-templates select="."/>
   </xsl:for-each-group>
 </xsl:copy>
</xsl:template>

In XML the order of attributes is usually irrelevant, but the above solution does not ignore order. But it works with any number of attributes.
