Just so everyone knows, some changes needed to be made:

The updated routine:
   sub formatCode{
      my $code = shift;
      my $prev_header = 0;                     # takes care of closing
+ divs
      for (split /\n/, $code) {                # No need to remove new
+lines
         if (/^\s*$/) { next }                 # Skip blank lines
         elsif ( /^(.*?)\[ ([^\]]*) \](.*)/x ) {      # If line is a h
+eader...
            print "$1</div>" if $prev_header;  #   close prev div, if 
+there was one...
            print qq(<div class="$2">$3);      #   print current div..
+.
            $prev_header = 1;                  #   and set current div
+ flag.
         }
         else { print "$_<br />" }             # Simply print non-head
+er lines
      }
      print "</div>" if $prev_header;          # You always have to cl
+ose last div, so just do it here
   }

Basically $1 needed to be changed to $_. Also, I added matches for before and after the tag, in case there was inline text. Finally, the line break was added in replace of a newline character. I'm still curious if $prev_header should be reset to 0 after the close div has been called. I guess it's not necessary.
