Logic to print data in required format for XML

Question

Hi,
Please find the xml format:
<ListOf_ssFsInvoice>
<ssFsInvoice>
<ListOf_ssFsInvoiceLineItems>
<ssFsInvoiceLineItems>
<ListOf_ssFsInvoiceLineItemDetails>
<ssFsInvoiceLineItemDetails>
<ssDnrmPartBillingType>Paid</ssDnrmPartBillingType>
<ListOf_ssFsInvoiceLineItemDetailTaxes>
<ssFsInvoiceLineItemDetailTaxes>
<ssTaxName>VAT</ssTaxName>
<ssAmount>1000</ssAmount>
</ssFsInvoiceLineItemDetailTaxes>
<ssFsInvoiceLineItemDetailTaxes>
<ssTaxName>Entry</ssTaxName>
<ssAmount>2000</ssAmount>
</ssFsInvoiceLineItemDetailTaxes>
<ssFsInvoiceLineItemDetailTaxes>
<ssTaxName>XYZ</ssTaxName>
<ssAmount>500</ssAmount>
</ssFsInvoiceLineItemDetailTaxes>
</ListOf_ssFsInvoiceLineItemDetailTaxes>
</ssFsInvoiceLineItemDetails>
</ListOf_ssFsInvoiceLineItemDetails>
</ssFsInvoiceLineItems>
</ListOf_ssFsInvoiceLineItems>
</ssFsInvoice>
</ListOf_ssFsInvoice>
Requirement:
1.For ssDnrmPartBillingType = Paid print total of ssAmount for similar ssTaxName and ssTaxName should appear only once in report for each ssTaxName.
2.e.g.
Line item 1:
Paid VAT 1000
Paid Entry 200
Paid XYZ 100
Line item 2:
Paid VAT 100
Paid Entry 100
Paid XYZ 50
Report Output
VAT 1100
Entry 300
XYZ 150
and so on.
How to use for each loop and sum function so that for all grouped items summation can be printed and repeated item appears only once that too in hierarchical structure as shown above.
Any suggestion?
Thanks in advance.

Answer 1

Try this:
<?for-each-group:ssFsInvoiceLineItemDetailTaxes;./ssTaxName?>
<?ssTaxName?> <?sum(current-group()/ssAmount[../../../ssDnrmPartBillingType='Paid'])?>
<?end for-each-group?>
This should give you the correct amounts.
