Trying to robustly parse a string that will have key/value pairs separated=
=0A=
by three pipes, where each additional key/value (if more than one exists)=
=0A=
will be delineated by four more pipes.=0A=
=0A=
    string =3D 'key_1|||value_1||||key_2|||value_2'=0A=
    regex =3D '((?:(?!\|\|\|).)+)(?:\|\|\|)((?:(?!\|\|\|).)+)(?:\|\|\|\|)?'=
=0A=
=0A=
I am not convinced this is the most effective or safest, any opinions would=
=0A=
be greatly appreciated!=0A=
