Hello shylaja,

As McA has shown, you can use the /g modifier in this way if you first read in the whole data file. But if the file is large, it may be necessary to process it line by line. For that, you need a different strategy; for example:

#! perl
use strict;
use warnings;
use Data::Dump;

my @fields = qw( Summary Component Product Version Date );
my @issues;

while (<DATA>)
{
    chomp;

    if (/^ISSUE\s+(\w{5}\d+)$/)
    {
        push @issues, { Id => $1 };
    }
    else
    {
        for my $field (@fields)
        {
            if (/^$field\s*:\s+(.+)$/)
            {
                $issues[-1]->{$field} = $1;
                last;
            }
        }
    }
}

dd \@issues;

__DATA__

Output:

    Component => "Component desscription ",
    Date => "2013-10-15",
