Actually, if the delimiter occurs at the start of the string, then split returns an empty string as the first portion. If passed a LIMIT of -1, it will also do the same at the end of the string. So if you really don't care about the lengths of the "abc" and "xyz" portions, it's simply:

use 5.010;
my $string = "abcFOOdefghFOOiFOOjklmFOOnopqrFOOstuvFOOwxyz";
my @portions = split /FOO/, $string, -1;
shift @portions;
pop @portions;
say "Lengths are:";
say $_ for map { sprintf("%d ('%s')", length, $_) } @portions;

As I said, the reason I didn't include the code to ignore the first and last portion of the string in my initial example is because it seemed obvious how it could be done.
