Ciao a tutti. Ho appena iniziato a lavorare con XML e XSLT ed ho questo problema.
Il mio file XML è del tipo
<?xml version="1.0"?>
<?xml-stylesheet type='text/xsl' href='ll.xslt'?>
<DocumentContent>
<VUSTAG Site="AON" Lat="Right">
<VASMEAS AG="CCA" TM="PR" VB="ME" CP="ES" EP="PP" Name="PSV" NumericValue="80" Unit="cm/s"/>
<VASMEAS AG="CCU" TM="PR" VB="ME" CP="ES" EP="PP" Name="PSV" NumericValue="88" Unit="cm/s"/>
<VASMEAS AG="CCA" TM="PR" VB="ME" CP="ES" EP="PP" Name="PSV" NumericValue="84" Unit="cm/s" DE="Mean"/>
<VASMEAS AG="CCU" TM="PR" VBr="ME" CP="ES" EP="PP" Name="PSV" NumericValue="80" Unit="cm/s"/>
<VASMEAS AG="CCU" TM="PR" VB="ME" CP="ES" EP="PP" Name="PSV" NumericValue="88" Unit="cm/s"/>
<VASMEAS AG="CCU" TM="PR" VB="ME" CP="ES" EP="PP" Name="PSV" NumericValue="84" Unit="cm/s" DE="Mean"/>
</VUSTAG>
<VUSTAG Site="AON" Lat="Left">

<VASMEAS AG="CCU" TM="PR" VB="ME" CP="ES" EP="PP" Name="PSV" NumericValue="88" Unit="cm/s"/>
<VASMEAS AG="CCU" TM="PR" VB="ME" CP="ES" EP="PP" Name="PSV" NumericValue="84" Unit="cm/s" DE="Mean"/>
<VASMEAS AG="CCA" TM="PR" VB="ME" CP="ES" EP="PP" Name="PSV" NumericValue="80" Unit="cm/s"/>

<VASMEAS AG="CCU" TM="PR" VB="ME" CP="ES" EP="PP" Name="PSV" NumericValue="84" Unit="cm/s" DE="Mean"/>

Ho preparato un foglio di trasformazione siffatto

ma purtroppo il raggruppamento è sbagliato perché produce tutti i sottorami CAA e CCU sotto la prima coppia AON Right.
Io vorrei una cosa del tipo:
AON Right
CAA
PR ME ES ...
PR ME ES ...
CCU
PR ME ES ...
PR ME ES ...
AON Left
CAA
...............
.............
CCU
.................
.................
cioè prima un raggruppamento in base a VUSTAG.Site e VUSTAG.Lat concatenati e in questo ambito un raggruppamento in base a VASMEAS.AG, il tutto senza ripetere l'intestazione. Grazie in anticipo a tutti. Gianni
