Using ABS and Sum function at a time

Question

<?if: sum(ARCH_AMT)!='0' ?>
we were using above condition in the template to restrict data till date,but we were facing a new problem when ARCH_AMT is having multiple lines with same amount but +ve and -ve i.e 500,-500 it's doing sum and not returning data since sum would be zero.
we need to do ABS(ARCH_AMT) before doing sum so that SUM will be thousand and data will be picked up.
please suggest how can we have ABS and sum at a time
i tried
<?if: sum(ABS(ARCH_AMT))!='0' ?> and also choose conditions and It's not working.
thanks in advance.
Kind Regards,
Mahi

Answer 1

store ABS(ARCH_AMT) in a variable, and use that variable in a running total
example:
suppose i have an xml structure like this:
<CATALOG>
<AMOUNT>
<ARCH_AMT>-500</ARCH_AMT>
</AMOUNT>
<AMOUNT>
<ARCH_AMT>500</ARCH_AMT>
</AMOUNT>
</CATALOG>
<?xdoxslt:set_variable($_XDOCTX,'vTotal',0)?>
<?xdoxslt:set_variable($_XDOCTX,'vAbsAmt',0)?>
<?for-each:AMOUNT?>
<?xdoxslt:set_variable($_XDOCTX,'vAbsAmt',xdoxslt:abs(ARCH_AMT))?>
<?xdoxslt:set_variable($_XDOCTX,'vTotal', xdoxslt:get_variable($_XDOCTX, 'vAbsAmt') + xdoxslt:get_variable($_XDOCTX,'vTotal'))?>
<?end for-each?>
Total: <?xdoxslt:get_variable($_XDOCTX, 'vTotal')?>
