just wrap a sum around it
<xsl:value-of select="sum(../../drawdownPosition/positionInfo/position
                  [positionTypeCode/upper-case(code) eq 'DRAWDOWNENDOFPERIODUNPAIDAMOUNT'][partyReference/@href eq $partyReference]
                  //positionAmounts/node()[name() eq  'positionAmount']/amount)"/>

please check its a for loop and i want to have sum for the both conditions
Example
the result of the above may give like this....

     0
     250
     350
     0
     500

now i want the sum as  [0 +  250 + 350 + 0 + 500] = 1100.
Acutally its and condition. i am not able to get the proper result when use xpath as
folllows

sum(../../../../../../../facilityPosition[positionInfo[position
                  [positionTypeCode/upper-case(code) eq 'FACILITYENDOFPERIODCONTENTIOUSAMOUNT'][partyReference/@href eq $partyReference]]
                  [position[positionTypeCode/upper-case(code) !='FACILITYENDOFPERIODUNPAIDAMOUNT']]]
                  /drawdownPosition/positionInfo/position[positionTypeCode/upper-case(code) eq 'DRAWDOWNENDOFPERIODUNPAIDAMOUNT']
                  [partyReference/@href eq $partyReference]//positionAmounts/node()[name() eq $elementName]/ag:getPositionAmount(amount, currency, $tag_Currency))

"sum(../../../../../../facilityPosition[positionInfo/position[positionTypeCode/upper-case(code) = 'FACILITYENDOFPERIODCONTENTIOUSAMOUNT']]/drawdownPosition/positionInfo/position
                  [positionTypeCode/upper-case(code) eq 'DRAWDOWNENDOFPERIODUNPAIDAMOUNT'][partyReference/@href eq $partyReference]
                  //positionAmounts/node()[name() eq  'positionAmount']/amount)"

will work (since the second condition returns zero, so you don't need to add them)

note that your XML has a namespace,
so facilityPosition does not exist, except in the namespace
since this seems to do something for you,
- you either have stripped out the namespace prior to your XSLT
- you are using default x-path namespace in XSLT2

if none of teh above is true, you need to add prefixes everywhere for that namespace

and...
usually there is little reason for not replacing ../../../../../../../facilityPosition
with ancestor::facilityPosition

the sum() by the way is outside the loop
