Please use code fences. How to use code fences

I don’t know if XPATH would provide a direct number parsing. Let’s try it that way:

rule "my rule"
when
    Item SNCBReply changed
then
    var String delaySecondInString = transform("XPATH", "/vehicleinformation/stops/stop[6]/departureDelay", SNCBReply.state.toString)
    var Number delaySecondInNumber = Integer::parseInt(delaySecondInString)
    logInfo("test", "In Number : {}",delaySecondInNumber) 
    var Number delayMinutes = delaySecondInNumber/60
    logInfo("test", "delayMinutes : {}",delayMinutes)
end
