Syntax to increment variable names in repeat loop

Thanks, Jim, The 'do' command looks useful as a mechanism for combining disparate elements - I'll add it to my armoury.

The multi-dimensional array should keep the XML strings related but separate for post processing. 
I'm also setting a custom property on the stack as the array - to provide simple database-free persistence over time and across cards, should I need to access the XML (or more likely, cross-reference the keys) from elsewhere in the stack.
Best,
Keith..
