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::langfam5.18

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

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. 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:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
