Hello Everyone,

Just seeking a favour to write a regular expression to match the following set of strings. I want to write an expression which matches all the following strings TCL

i) ( XYZ XZZ XVZ XWZ )

Clue : Starting string is X and Z ending string is same for all the pairs. Only the middle string is differs Y Z V W.

My trial: [regexp {^X([Y|Z|V|W]*)Z$}]

I want to write an another regexp which catches/matches only the following string wherever comes

ii) (XYZ)

My trial: [regexp {^X([Y]*)Z$}]
