Extracting substring within string between 2 token within the string
Hello.


First best wishes for everybody.


here is the input file ("$INPUT1") contents :
Code:
BASH_FUNC_message_begin_script%%=() {  local -a L_ARRAY;
BASH_FUNC_message_debug%%=() {  local -a L_ARRAY;
BASH_FUNC_message_end_script%%=() {  local -a L_ARRAY;
BASH_FUNC_message_error%%=() {  local -a L_ARRAY;

This simple sed command works well for some kind of tokens.
These tokens work well

Code:
TOKEN1="^BASH_FUNC_"
TOKEN2="\%\%\=\(\)"
#
# # between but excluding TOKEN1 and TOKEN2
#
sed -e 's/'$TOKEN1'\(.*\)'$TOKEN2'.*/\1/'  "$INPUT1"

Which return :
Code:
message_begin_script
message_debug
message_end_script
message_error

Another working example
Code:
#
# # between but including TOKEN1 and excluding TOKEN2
#
sed -e 's/\('$TOKEN1'.*\)'$TOKEN2'.*/\1/'  "$INPUT1"

which return
Code:
BASH_FUNC_message_begin_script
BASH_FUNC_message_debug
BASH_FUNC_message_end_script
BASH_FUNC_message_error

Now I have another token2 of this kind : TOKEN2="local -a L_ARRAY"
And I got an error
Code:
TOKEN1="^BASH_FUNC_"
TOKEN2="local -a L_ARRAY"
#
# # between but excluding TOKEN1 and TOKEN2
#
sed -e 's/'$TOKEN1'\(.*\)'$TOKEN2'.*/\1/'  "$INPUT1"

Code:
sed -e 's/'^BASH_FUNC_'\(.*\)'local -a L_ARRAY'.*/\1/'  "/tmp/MY_INPUT1.txt" 
sed: -e expression #1, char 24: unterminated `s' command

I have tried to escape space and '-' without success
Any help is welcome

locale::codes::langvar

Locale::Codes::LangVar(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangVar(3pm)

NAME

       Locale::Codes::LangVar - standard codes for language variation identification

SYNOPSIS

	  use Locale::Codes::LangVar;

	  $lvar = code2langvar('acm');		       # $lvar gets 'Mesopotamian Arabic'
	  $code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langvar_codes();
	  @names   = all_langvar_names();

DESCRIPTION

       The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language variations. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lvar = code2langvar('en','alpha-2');
	  $lvar = code2langvar('en',LOCALE_CODE_ALPHA_2);

       The codesets currently supported are:

       alpha
	   This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian.

	   This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".

	   This is the default code set.

ROUTINES

       code2langvar ( CODE [,CODESET] )
       langvar2code ( NAME [,CODESET] )
       langvar_code2code ( CODE ,CODESET ,CODESET2 )
       all_langvar_codes ( [CODESET] )
       all_langvar_names ( [CODESET] )
       Locale::Codes::LangVar::rename_langvar  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangVar::add_langvar  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangVar::delete_langvar  ( CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangVar::delete_langvar_alias  ( NAME )
       Locale::Codes::LangVar::rename_langvar_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::delete_langvar_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
