Hi Godwin, According to [1] fn:sum is used to make sum of some xpath objects, for example if the payload is [2], then "fn:sum(//order//item/@quantity)" will return you the value 11. So I think you can't use fn:sum to just add two numbers together.
[1] - https://www.w3.org/TR/xpath-functions/#func-sum [2] - <order num="00299432" date="2006-09-15" cust="0221A"> <item dept="WMN" num="557" quantity="1" color="beige"/> <item dept="ACC" num="563" quantity="1"/> <item dept="ACC" num="443" quantity="2"/> <item dept="MEN" num="784" quantity="1" color="blue/white"/> <item dept="MEN" num="784" quantity="5" color="blue/red"/> <item dept="WMN" num="557" quantity="1" color="sage"/> </order> Thanks, On 6 August 2016 at 01:55, Godwin Shrimal <god...@wso2.com> wrote: > Hi Udara, > > Yeah, we can use script mediator as an alternative, I need to know weather > we can use fn:sum or is it not working in ESB. > > Thanks > Godwin > > On Fri, Aug 5, 2016 at 3:19 PM, Udara Liyanage <ud...@wso2.com> wrote: > >> Hi Godwin, >> >> As a workaround following worked for me.
