Hello again rohan_532,

You are mixing many questions and issues here.

Having a case sensitive string is something different that comparing with a regex with numbers. So take a step backwards and analyze it.

If you have an upper case string and you want to convert it to a lower case you can simply use lc or the opposite assume that you have a lower case string and you want to convert to upper case uc. Or even igf you manage to split the string into pieces and you want to make only the first letter of the string upper case ucfirst.

Regarding the regex part of your question:

#!usr/bin/perl
use strict;
use warnings;

my @steps_name = ("1-2 Steps", "5-7 Steps", "8-10 Steps", "11-15 Steps
+");

foreach my $element (@steps_name) {
        print "Matched with ".$element."\n" if ($element =~ /[0-9]-[0-
+9]/);
}

__END__

$ perl test.pl
Matched with 1-2 Steps
Matched with 5-7 Steps
Matched with 8-10 Steps
Matched with 11-15 Steps
[download]

As you can see this will match with all elements, so you need to be a bit more specific on what you want to compare against. For example 1-2 Steps only, or multiple choices?

Again I am looking forward to update your question with more details.

Update: Have you read the answers that marinersk and AnomalousMonk have already provided you on your previous question regex for case insensitive? I looks like they have already addressed your problem.

Hope this is more clear now, programming gives you infinite possibilities, you have to tell us exactly what is the desired output.

apologies for the re posting and incorrect process,I have read the answer but the scenario is different i have on fixed array with standard data and repeating variable ($db_description) to compare with the array. The comparing will be done for multiple choice . Example:- The description variable value is the one to compare in array.

Hello rohan_532,

I am sorry but I am not able to understand what you mean.

I will try guess your way of thinking and you can verify or falsify or correct me if this is what you are looking for.

Based on your answer Example:- The description variable value is the one to compare in array., let's create a scenario with sample data something that YOU should have done so we will be able to replicate the problem.

#!usr/bin/perl
use strict;
use warnings;

# Variables that I will extract from the escel sheet
my @steps_name = ("1-2 Steps", "5-7 Steps", "8-10 Steps", "11-15 Steps
+");

#regex that I want to match against
foreach (@steps_name) {
        print "Matched with ".$_."\n" if /(?:\b8-10 Steps\b|\b11-15 St
+eps\b)/;
}

__END__

$ perl test.pl
Matched with 8-10 Steps
Matched with 11-15 Steps

You can combine regular expression if, if this is what you are looking for. Provide us a sample of expected input and desired matched output. It does not have to be compiling code, produce a pseudo code.

Update: Apologies if I sounded a bit harsh but we need to know what exactly you are looking for, so we can help you as soon as possible. If your question is still not answered please provide us more information.

Hope this helps.
