Re^2: Reg Exp

Hi psini,

That solution seems to be not fit here. In the 'test1' string, there is no parantheses to split, so it will obviously fail and you can't split the string.

OP wants to match the 'test1' string where the platform is missing and which is present in 'test' string.

Yep, I realized it reading the other answers, sorry

Actually, IFF (if and only if) there are only the 2 variations presented in the OP, you could just use a

@arr=split(/ /,$test);

... and count the size of the array

$size=scalar(@arr);

if its 4, arr[2]is the OS, otherwise no OS was specified
