Need Help??

in reply to Store result of split directly to variable(s)

Hello Perl_Ally,

Here are two methods:

(1) Subscript the list returned by split:

 2:26 >perl -Mstrict -wE "my @data = ('A: A_value', 'B: B_value'); for
+ (@data) { my $a = (split /: /)[1]; say $a; }"
A_value
B_value

 2:30 >

(2) Assign the unwanted value to undef:

 2:30 >perl -Mstrict -wE "my @data = ('A: A_value', 'B: B_value'); for
+ (@data) { my (undef, $a) = split /: /; say $a; }"
A_value
B_value

 2:30 >

Hope that helps,
