Problema Regex

[zacca94]

[ LIST ][*] A[*] B[*] C
[ / LIST ]

preg_match_all( "#\
[list\]\s*(\[\*\](.*?))+\s*\[/list\]#is", $text, $out);

Vorrei selezionare in una array
0 => [*] A
1 => [*] B
2 => [*] C

Però non va...

[ciro78]

ma sarebbe più semplice ripulire la stringa dei tag list e [*] sostituendoli con "" e poi usare explode ?

ma sarebbe più semplice ripulire la stringa dei tag list e [*] sostituendoli con "" e poi usare explode ?

no impossibile, poi come farei in caso di <list> annidate, tag [*] sparsi in giro per il codice o bbcode mal inserito?

comunque ho risolto in questo modo, posto il codice nel caso fosse d'aiuto a qualcuno:
