Grep string causes extra spaces
Hello,
I have an xml file and my aim is to grab each line in keywords file and search the string in another file.
When keyword is found in xml file,I expect the script to go to previous line in the xml file and grab the string/value between two strings. It's almost working with an error.

tab separated keywords.txt
Code:
test1 qqq98
test35 sss32
test26 Rsiw

1.xml file
Code:
  <id="229954e70d6b702f8d570b4be11af181">
    <display-name>test44 lgi3d</display-name>
  <id="229954e70d6b702f8d51331cbe11af181">
    <display-name>test35 kkld</display-name>
  <id="2223230did3s2Qafevrgvve1cbe11af181">
    <display-name>test26 Rsiw</display-name>

expected output:
Code:
test1 qqq98 id=""
test35 sss32 id=""
test26 Rsiw id="2223230did3s2Qafevrgvve1cbe11af181"

Code:
while read COL1 COL2 && read -r line <&3; do
A=$(grep -B1 "$COL1.*$COL2" 1.xml | grep -v "display-name" | sed -e 's/<id=\"\(.*\)\">/\1/' )
#A=$(grep -B1 "$COL".*$COL2" 1.xml | grep -v "display-name" | grep -o -P '(?<=<id=\").*(?=\">)')
echo "$COL1 $COL2 id=\"$A\""
done < keywords.txt 3<1.xml

This gives:
Code:
test1 qqq98 id=""
test35 sss32 id=""
test26 Rsiw id="  2223230did3s2Qafevrgvve1cbe11af181"

I wondered why there are two spaces before $A variable at output console.

Thank you
Boris

locale::script

Locale::Script(3perl)					 Perl Programmers Reference Guide				     Locale::Script(3perl)

NAME

       Locale::Script - standard codes for script identification

SYNOPSIS

	  use Locale::Script;

	  $script  = code2script('phnx');		      # 'Phoenician'
	  $code    = script2code('Phoenician'); 	      # 'Phnx'
	  $code    = script2code('Phoenician',
				 LOCALE_CODE_NUMERIC);	      # 115

	  @codes   = all_script_codes();
	  @scripts = all_script_names();

DESCRIPTION

       The "Locale::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924
       four-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying scripts. The ones currently supported are:

       alpha
	   This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.

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

	   The Zxxx, Zyyy, and Zzzz codes are not used.

	   This is the default code set.

       numeric
	   This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician.

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

ROUTINES

       code2script ( CODE [,CODESET] )
       script2code ( NAME [,CODESET] )
       script_code2code ( CODE ,CODESET ,CODESET2 )
       all_script_codes ( [CODESET] )
       all_script_names ( [CODESET] )
       Locale::Script::rename_script  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Script::add_script  ( CODE ,NAME [,CODESET] )
       Locale::Script::delete_script  ( CODE [,CODESET] )
       Locale::Script::add_script_alias  ( NAME ,NEW_NAME )
       Locale::Script::delete_script_alias  ( NAME )
       Locale::Script::rename_script_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::add_script_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::delete_script_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes man page.
