Re: Sorting unique and sub-total problem

I have final got what I want... and learnt a hell of a lot in the
process...
A combination of syntax and typos held me back some what... but I crawled
forward ...

Although looking that the other postings it is clear that I am way out of
my league.  But  I still thought it was worth posting the end result....

Thanks to Wendel and Mukul for the help...

XSL IS....

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
      xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:key name="cards" match="ITEM" use="CARD/@number" />

<xsl:template match="/">
      <xsl:for-each select="/ITEMS" >
            <xsl:call-template name="create-body" />
      </xsl:for-each>
</xsl:template>

<xsl:template name="create-body" >
      <xsl:for-each select="./ITEM[CARD/@number and
            generate-id(.) = generate-id(key('cards', CARD/@number))]" >

                  <BR/> VALUES FOR CARD: <xsl:value-of select
="CARD/@number"/>
                  <BR/> NUMBER OF ITEMS: <xsl:value-of select="count(key
('cards', CARD/@number))" />
                  <xsl:for-each select="key('cards', CARD/@number)" >
                        <BR/> Values <xsl:value-of select="AMOUNT/@amt" />
                  </xsl:for-each>
                  <BR/> TOTAL: <xsl:value-of select=" sum( key('cards',
CARD/@number)/AMOUNT/@amt )  "/>
                  <BR/>
      </xsl:for-each>
      <BR/> GRAND TOTAL: <xsl:value-of select="sum(//AMOUNT/@amt)" />
</xsl:template>
</xsl:stylesheet>


AND THE XML IS...

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="test.xsl"?>

<ITEMS>

      <ITEM item_id='1'>  <CARD number='123456789' amt='1'/>  <AMOUNT amt
='100'/>   </ITEM>
      <ITEM item_id='2'>  <CARD number='123456789' amt='2'/>  <AMOUNT amt
='200'/>  </ITEM>
      <ITEM item_id='3'>  <CARD number='987654321' amt='3'/>  <AMOUNT amt
='30'/>  </ITEM>
      <ITEM item_id='4'>  <CARD number='123456789' amt='4'/>  <AMOUNT amt
='50'/>  </ITEM>
      <ITEM item_id='5'>  <CARD number='987654321' amt='5'/>  <AMOUNT amt
='150'/>  </ITEM>
      <ITEM item_id='6'>  <CARD number='123456789' amt='6'/>  <AMOUNT amt
='250'/>  </ITEM>

</ITEMS>

WHICH GIVES ME THIS....

VALUES FOR CARD: 123456789
NUMBER OF ITEMS: 4
Values 100
Values 200
Values 50
Values 250
TOTAL: 600

VALUES FOR CARD: 987654321
NUMBER OF ITEMS: 2
Values 30
Values 150
TOTAL: 180

GRAND TOTAL: 780
