Write Code to Convert Groovy (Java) Map/Array Output to XML

I will be sending several examples of working Groovy code I have written to the successful applicant. I have successfully written the code to turn XML input into a Groovy Map (it might actually be an array, I'm a bit of a noob). You will be able to see this in the attached files. What I am looking for from you, is the code to turn Groovy's map/array (not sure which it is) output into XML output. Each key/value pair should be on a single carriage-return delimited line likethis anotherexample I need the map/array output converted to XML output for 3 functions. They are currently outputting in what is either a groovy map or array.
