XSLT 2.0 SUM hodnôt, kde sa obsah uzla rovná špecifickej hodnote - xml, xslt, xpath, group-by, xslt-2.0

Mám nejaké zoskupenie údajov o nákladoch, ktoré je možné označiť ako HCOST alebo SCOST v súbore XML pod zakladateľ uzol.

Hľadám výsledok:

Hard Costs:  $600.00
Soft Costs:  $200.00

Tu je môj XML:

<?xml version="1.0" encoding="utf-8"?>
<superbills>
<superbill>
<invoice>
<matters>
<matter>
<cost-detail>
<costcards>
<costcard index="1234">
<cledger>HCOST</cledger>
<card-values>
<card-value type="billed">
<rate>200.00</rate>
<quantity>1.00</quantity>
<amount>200.0000</amount>
</card-value>
</card-values>
<costcard index="2345">
<cledger>SCOST</cledger>
<card-values>
<card-value type="billed">
<rate>100.00</rate>
<quantity>1.00</quantity>
<amount>100.0000</amount>
</card-value>
</card-values>
</costcard>
<costcard index="3456">
<cledger>HCOST</cledger>
<card-values>
<card-value type="billed">
<rate>200.00</rate>
<quantity>1.00</quantity>
<amount>200.0000</amount>
</card-value>
</card-values>
</costcard>
<costcard index="4567">
<cledger>SCOST</cledger>
<card-values>
<card-value type="billed">
<rate>100.00</rate>
<quantity>1.00</quantity>
<amount>100.0000</amount>
</card-value>
</card-values>
</costcard>
<costcard index="5678">
<cledger>HCOST</cledger>
<card-values>
<card-value type="billed">
<rate>200.00</rate>
<quantity>1.00</quantity>
<amount>200.0000</amount>
</card-value>
</card-values>
</costcard>
</costcard>
</costcards>
</cost-detail>
</matter>
</matters>
</invoice>
</superbill>
</superbills>

Tu je aktuálny XSLT, ktorý používam: (Snažím sa iba o časť „HCOST“ a vo výsledku dostávam iba 200,00 dolárov, nie sumu 600,00 dolárov, ktorú požadujem)

odpovede:

Ak používate XPath, ako v format-number(sum(/superbills/superbill/invoice/matters/matter/cost-detail/costcards/costcard[cledger="HCOST"]/card-values/card-value[@type="billed"]/amount), "$#,##0.00;-$#,##0.00"), potom zoskupenie nepotrebujete.

XSLT ...
