how to ignore spaces, commas or new line of an array when comparing

noviceuser has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to compare two arrays which may have strings/elements separated by newline, spaces or comma, how can i ignore those special characters while comparing

e.g: suppose @array1 has contents like below

abc xyz

and @array2 has contents like below

abc
 xyz

my $comp = Array::Compare->new;
    if ($comp->compare(\@array1, \@array2)) {
      print "array same\n";
    }
    else {
      print "array not same\n";
    }

That almost sounds like the use case for the WhiteSpace option. Did you try that? If you still have problems, I recommend that you show precisely how your arrays are created. eg: `my @array1 = ('abc ', 'xyz');` [download] ... and so on. This removes any ambiguity about the data you actually have. 🦛	[reply] [d/l]

in @array1, the contents are being pushed and in @array2, the contents are being read from a file and stored in the @array2	[reply]

How does that reply address "show precisely how your arrays are created" (see I know what I mean. Why don't you?)? Perhaps you intended to write something like: `use strict; use warnings; my $fStr = <<FSTR; abc xyz FSTR open my $inFile, '<', \$fStr; my @array2 = <$inFile>; my @array1 = ('abc ', 'xyz');` [download] Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond	[reply] [d/l]

Hmmm. Is your real question then "How do I clean whitespace from data read from a file?" or something like that? Or do you really want one array with whitespace and one without? 🦛	[reply]
