Perl script: matching multiple lines error
Dear Perl users,

Could somebody help me how to fix my code so I can get my desired output.
Here is the data:
Code:
Pattern Gabriel
halo1
halo2
end
Pattern Andreas
halo1
halo2
end

I want to grep multiple lines between the pattern /Pattern Gabriel / and /end/.
Then I will store the output into two files (let's say Gabriel.log and Andres.log based on the name).

Code:
The Gabriel.log contains:

Code:
Pattern Gabriel
halo1
halo2
end



Code:
The Andreas.log contains:

Code:
Pattern Andreas
halo1
halo2
end

I saw there is a similar solution that I found but the desired output isn't valid yet.
here is my code so far:

Code:
#!/usr/bin/perl -w
use strict;

my @result;
my $flag = 0;
my @data = qw /Gabriel Andreas/;

while (my $line = shift @data)
{
  if (open (EXT, ">${line}.log"))
  {

  if (open (FILE, "<data_test.log"))
  {
  
  while (<FILE>) 
    {
      
      if (/Pattern\s+($line)/i) 
      {
       $flag = 1;
      } 
      elsif( /^end/ ) 
      {
       $flag = 0;
      }
      if ($flag) 
      {
        push @result, $_;
      }
    }

  print EXT "$_" for (@result);

  }
  }
}  
close (EXT);
close (FILE);
