XOR Gateway expression

Question

Hi, 
 I am taking the service name from drop down field from interface and mapping it to following variable. 
 
 After that I am uploading excel as below: 
 
 Following is the rule I am using in script task and saving its value into Boolean type variable 'flag'. 
 
 My requirement is if pv!Service_name=pv!cdt.srvc_nm then it should go to XOR path otherwise send email path. 
 
 if I change the value in excel rows the flow is not going in appropriate way. 
 Thanks, 
 Kiran

 Well as I said below , contains() will match any entries. 
 For checking whether all entries match a given value, you can use a!forEach for an easy-to-understand alternate method: 
 and(
 a!forEach(
 pv!cdt.srvc_nm,
 fv!item = pv!Service_name
 )
) 
 In the above code snippet, the internal a!forEach() generates an array of boolean values i.e. {true(), false(), true()} etc; if all entries in the array match, these will all be true() , and thus the outer and() will also return true .

 TIP: In this code block, you can eliminate the if() condition as the contains() function will give you a boolean value itself. 
 Now to debug the problem, did you check if both the variables are populating correctly in the process details of the instance? If yes, then try to wrap the parameters of contains() function in touniformstring() and tostring() respectively. That should solve the problem.

contains() will return true if ANY items in the array match. thus your pv!flag will be set to TRUE, and the "XOR" path will be executed.
