Full Discussion: SED - replace only on part of the string

I see a pattern here... All the commas you don't want replaced are right after a bracket. So we match a not-bracket with a comma after it, putting the not-bracket into the backreference, and putting a | where the comma was. So:

Code:
$ echo "PARM1=(VAL11),PARM2=(VAL21,VAL22,VAL23),PARM3=(VAL31),PARM4=(VAL41,VAL42)" | sed 's/\([^)]\),/\1|/g'

PARM1=(VAL11),PARM2=(VAL21|VAL22|VAL23),PARM3=(VAL31),PARM4=(VAL41|VAL42)

ppix::regexp::constant

PPIx::Regexp::Constant(3pm)				User Contributed Perl Documentation			       PPIx::Regexp::Constant(3pm)

NAME

       PPIx::Regexp::Constant - Constants for the PPIx::Regexp system

SYNOPSIS

	use PPIx::Regexp::Constant qw{ TOKEN_UNKNOWN }
	print "An unknown token's class is TOKEN_UNKNOWN
";

INHERITANCE

       "PPIx::Regexp::Constant" is an Exporter.

       "PPIx::Regexp::Constant" has no descendants.

DETAILS

       This module defines manifest constants for use by the various "PPIx::Regexp" modules. These constants are to be considered private to the
       "PPIx::Regexp" system, and the author reserves the right to change them without notice.

       This module exports the following manifest constants:

   COOKIE_CLASS
       The name of the cookie used to control the construction of character classes.

       This cookie is set in PPIx::Regexp::Token::Structure when the left square bracket is encountered, and cleared in the same module when a
       right square bracket is encountered.

   COOKIE_QUANT
       The name of the cookie used to control the construction of curly bracketed quantifiers.

       This cookie is set in PPIx::Regexp::Token::Structure when a left curly bracket is encountered. It requests itself to be cleared on
       encountering anything other than a literal comma, a literal digit, or an interpolation, or if more than one comma is encountered. If it
       survives until PPIx::Regexp::Token::Structure processes the right curly bracket, it is cleared there.

   COOKIE_QUOTE
       The name of the cookie used to control the parsing of "Q ... E" quoted literals.

       This cookie is set in PPIx::Regexp::Token::Control when a "Q" is encountered, and it persists until the next "E".

   MINIMUM_PERL
       The minimum version of Perl understood by this parser, as a float. It is currently set to 5.000, since that is the minimum version of Perl
       accessible to the author.

   MODIFIER_GROUP_MATCH_SEMANTICS
       The name of the PPIx::Regexp::Token::Modifier group used to control match semantics.

   RE_CAPTURE_NAME
       A string representation of a regular expression that matches the name of a named capture buffer.

   STRUCTURE_UNKNOWN
       The name of the class that represents the unknown structure. That is, PPIx::Regexp::Structure::Unknown.

   TOKEN_LITERAL
       The name of the class that represents a literal token. That is, PPIx::Regexp::Token::Literal.

   TOKEN_UNKNOWN
       The name of the class that represents the unknown token. That is, PPIx::Regexp::Token::Unknown.
