How to get only one of two items returned

In a mapper snap, my current expression is: $[‘env:Envelope’][‘env:Body’][‘ns0:uploadFileToUcmResponse’].result[‘$’] I only want the second value “123109” returned as a string. How can I do this?...

@swright array[1] , it will give you 2nd value. for your case it looks like-

[‘env:Envelope’][‘env:Body’][‘ns0:uploadFileToUcmResponse’].result[‘$’][1]
or
[‘env:Envelope’][‘env:Body’][‘ns0:uploadFileToUcmResponse’].result[1]

    I had tried these before and I think that they should have worked but they didn’t.

    The first one changed the values to 1 and 2 which isn’t what I want:

    $[‘env:Envelope’][‘env:Body’][‘ns0:uploadFileToUcmResponse’].result[‘$’][1]

    The second one failed with:

    reason":

    “‘1’ was not found while evaluating the sub-expression ‘$[‘env:Envelope’][‘env:Body’][‘ns0:uploadFileToUcmResponse’].result[1]’”

    I also tried the following that failed:

    $[‘env:Envelope’][‘env:Body’][‘ns0:uploadFileToUcmResponse’].result[‘$’].pop()

    It failed with:

    "String type does not have a method named: pop, found in: …sult[‘$’].pop().

    Thanks,
