Hi i am writing a perl. script to extract out the number of errors with each code as a summary. The input is like this

A_01: xxxxxxx
xxxxxxxxxx
xxx......... 1 violation

A_02: xxxxxxx
xxxxxxxxxx
xxx......... 4 violations
B_02: xxxxxxxx
xxxxxxxxxx
xxx......... 3 violations

So, from the input, basically i have to grep from A_01 until 1 violation, and from here to there is about 3 lines, and the output is like this: 

A number of violations = 5;
B number of violations = 3;

But, my code is only able to read the violations all though, and sum it out. My code is like tis: 

  open(DATA, "<abc.txt, $!";

   $num = 0; 
   
   while (<DATA>){
  
   while (<DATA>){
   if ( (($_ =~ /violation/) || ($_ =~ /violations/)))  {
          if ($_ =~ /(\d+)/) {
          $num = $num + $1;
         }
     }
   
}
   
if ($num == 0) {
print "DM0$x ....... CLEANED\n"
} else {
print "DM0$x ....... Total = $num violations\n"
}
}
