will be helpful for those in need Agreed about using a non-regex method for this, as this can get unwieldy fast. But if you're curious, read on.
Technically, the comma you wish to find is in a group of parentheses, enclosed in max(). If you only ever want to look inside a single top-level function, you can use something such as this:
code :
(?:^max\\(|(([\'\"])(?:\\\\.|(?!\\g{-1}).)*+\\g{-1})|\\((\\\\.|(?1)|[^()\'\"]|\\((?-1)*+\\))*+\\))(*SKIP)(?!)|,

may help you . I have one string , You can use this regex:
code :
String input = "5,(5,5),C'A,B','A,B',',B','A,',\"A,B\",C\"A,B\"";
String[] toks = input.split( 
                ",(?=(([^']*'){2})*[^']*$)(?=(([^\"]*\"){2})*[^\"]*$)(?![^()]*\\))" );
for (String tok: toks)
    System.out.printf("<%s>%n", tok);
<5>
<(5,5)>
<C'A,B'>
<'A,B'>
<',B'>
<'A,'>
<"A,B">
<C"A,B">
,                         # Match literal comma
(?=(([^']*'){2})*[^']*$)  # Lookahead to ensure comma is followed by even number of '
(?=(([^"]*"){2})*[^"]*$)  # Lookahead to ensure comma is followed by even number of "
(?![^()]*\\))             # Negative lookahead to ensure ) is not followed by matching
                          # all non [()] characters in between

hop of those help? You can do this with Parse::RecDescent, which lets you define a grammar for parsing:
code :
use strict;
use warnings 'all';
use 5.010;

use Data::Dumper;
use Parse::RecDescent;
use Regexp::Common qw(balanced);

my $grammar = q{
    # One or more fields, separated by commas
    startrule     : field(s /,/)                                                        # / for broken Stack Overflow syntax highlighter

    # A field can be a function call, a double-quoted string, or bare text
    field         : func
                  | quoted
                  | bare

    # A double-quoted string. Returned with quotes stripped
    quoted        : /"[^"]*"/
                  {
                      $item[-1] =~ s/\A"|"\z//g;                                        # / for broken Stack Overflow syntax highlighter
                      $return = $item[-1]
                  }

    # "Bare" text: not a function call and not a quoted string. May contain
    # spaces
    bare          : /[^,]*/

    # A function name
    identifier    : /\w+/
};

$grammar .= qq{
    # A function call
    func          : identifier /$RE{balanced}{-parens=>'()'}/
};

$grammar .= q{
                  { $return = join '', @item[1..$#item] }
};

my $parser = Parse::RecDescent->new($grammar) or die 'Bad grammar';

my $parsed = $parser->startrule(
    'one two, "string with ,", func(a,func2(1,2))'
);
print Dumper $parsed;
$VAR1 = [
          'one two',
          'string with ,',
          'func(a,func2(1,2))'
        ];
