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.
