splitting a $ variable into several variables
my subject may not be too clear, but i have a variable called $output =
20120608|Friday|08-Jun-2012|Open|zzzzz
20120609|Saturday|09-Jun-2012|Open|zzzzz
20120615|Friday|15-Jun-2012|Open|zzzzz
20120616|Saturday|16-Jun-2012|Open|zzzzz
20120622|Friday|22-Jun-2012|Open|zzzzz
20120623|Saturday|23-Jun-2012|Open|zzzzz
20120629|Friday|29-Jun-2012|Open|zzzzz
20120630|Saturday|30-Jun-2012|Open|zzzzz

each line in the variable ends with \n

i want to read each line individually and split at the | and access each field separately. if i were reading the lines from a file, i know how to do it. but i can't figure out how to split the lines of the variable. i tried

@lines = $output and @lines = split('\n',$output) and several other things. so far, nothing works. help please. thanks.

Code:
foreach (split /\n/, $data) {
chomp;
my @vals = split /|/, $_;

print "Field 1 value is: $vals[0], and field 2: $vals[1] etc \n"

}

Hope that helps.

Cheers

i had tried something similar to that but it didn't work. i found this somewhere:

my @array = $data =~ /\G(?=.)([^\n]*)\n?/sg;

don't know why but it works. would like to understand if you can explain it to me! thanks

Hi,

From what it looks like, its extracting the values into the array using a loop. Personally, I would go with my code (as its more readable). Its untested, but I can't see any reason why it wouldn't work.

ok, i thought what i had was working but discovered it was not printing the last record.here's what i have now:

foreach (split /\n/, $records) {
chomp;
my @vals = split /|/, $_;

print "Field 1 value is: $vals[0], and field 2: $vals[1] etc \n"

}

this is what it printed:

Field 1 value is: 2, and field 2: 0 etc Field 1 value is: 2, and field 2: 0 etc

it should have printed Saturday 05-may-2012 Saturday 12-may-2012
