separating lines

I am using GET_TEXT_AS_R3TABLE from cl_gui_textedit class, and i obtein some lines in a table with ## marking the line jump, but i don´t know how to do it, because if i try to split at '##' it doesn´t do it, have i to convert one by one characters to ascii code or is there any way to do it?,

Thanks in advance.

example:

xxxxxxxx##ccc##vv####

i want:

xxxxxxxx##

ccc##

vv####
