im not really good in regex...but this is something that is making me pull my hair. Basically, im trying to read from a result file that is something like this : 
Title               Percent2   Percent3
test1.cpp     0.00% of 21     0.00% of 16
test2.c     None   16.53% of 484
test3.h         0.00% of 138    None

I'm trying to extract Title, Percent2, and Percent3 into individual variables. Percent2 and Percent3 can be percentage or 'None'. Here's what I did : 
#!perl
local @match;

open(FILE_EXPECTED_RESULT, "< gcov_report.txt");
    while(<FILE_EXPECTED_RESULT>)
    {
        chomp($_);
        if ($_ ne "")
        {
           print $_ . "\n";

            (@match) =($_ =~ /((.*\.c\s)|(.*\.h\s)|(.*\.cpp\s))|(\s+(.
+*)\%\s+(of)\s+\d+\s)|(\bNone\b)/g);
           
            print "title : ".$match[0]."\n";
            print "percent2 : ".$match[1]."\n";
            print "percent3 : ".$match[2]."\n";
       
         
        }
    }
close (FILE_EXPECTED_RESULT);

it is returning weird stuff : 
Title               Percent2   Percent3
title :
percent2 :
percent3 :
test1.cpp     0.00% of 21     0.00% of 16
title : test1.cpp
percent2 :
percent3 :
test2.c     None   16.53% of 484
title : test2.c
percent2 : test2.c
percent3 :
test3.h         0.00% of 138    None
title : test3.h
percent2 :
percent3 : test3.h
