The missing output for the third line of the given code suggests that the code and output simply don't belong to each other. On that basis no further speculation as to why it doesn't DWIM seems reasonable. Look at it from our point of view -- there could be about anything in the real code/output matching pair.
Thanks for the heads up, seems when called the routing the value i was parsing to regex was not complete, so hence the print of all lines into the output file. Thanks team
