[TxMt] OT: Perl Compatible Regex problem I can't solve

[Erich Ocean]

Why are you using a regex for this? Why not simply split the string 
using '/' as the delemiter, and get the results back in an array? Then 
you can used indexed access and get the "captures" that way. Or perhaps 
I'm missing something here...

Best, Erich
