for the given xml shown below, I would get a grand total per each
currency...
This is first a grouping problem to establish the unique values for currency.
I guess I can do something like
sum(/REPORT/ENTITY/FUND_GROUP/ROW/SOME_VALUE) along with "xsl:if", but I'd
like to avoid scanning through the tree again looking up CURRENCY
attribute... any suggestion?
Then a simple XPath expression qualifying the currency you want.
I hope the example below helps.
