I have flow that makes a request to soap service, and before the request I need to transform input json into xml:

I tried setting Qualified Name as dynamic property

%dw 2.0
output application/xml
ns ns0 http://tempuri.org/
---
 {
 
 ("ns0#" ++ (vars.operation)): {
        ns0#intA: payload.val1,
        ns0#intB: payload.val2
    } 
}

but when i make postman request i get: Error consuming the operation [Divide], the request body is not a valid XML

I made it dynamic using if and else:

{
    (
        if (payload.operation == "Add") {
            ns0#Add: {
                ns0#intA: payload.val1,
                ns0#intB: payload.val2
            }
        } else if (payload.operation == "Multiply") {
            ns0#Multiply: {
                ns0#intA: payload.val1,
                ns0#intB: payload.val2
            }

But I was hopping for more dynamic solution
