I posted a similar problem last week that required a somewhat more complex
answer but received no responses to it, so I have reduced my requirements
and simplified the problem substantially. 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>
where the <Formats se-tenant="365" appears twice. What I desire is:
<FormatPage souvenir-sheet="365">
<FormatButtons>
<Formats se-tenant="365"/>
<Formats coupon="367"/>
<Formats coupon="368"/>
</FormatButtons>
</FormatPage>
Thanks,
Mark
