Ok, you can only catch shadow pokemon in XD if they are the wild pokemon, hadow pokemon in thi game are generated so that if they are created with a code thaat makes them shiny, the game will re create the code until it isnt shiny , also i cant find confirmation about thi anywhere but i have also had the starter eevee shiny before but other than that ALL shadow pokemon get re-rolled until they arent shiny because of a glitch in colliseum
Source: Bulbapedia would have poted link but my account is too new
However they are catchable in Colliseum but once again the whole reason you cant in XD is because of a glitch
