I'm trying to use regex expression to label my layer in order to show the parcel number.
Here is some examples of what i'm looking for :
From this "53042A0027/00M002", to "A27M/2"
From this "53042A2000/02A003", to "A2000A2/3"
From this "53042C0002/00_000", to "A2"
From this "53042G1257/00X000", to "G1257X"
