Read from a file and replace it in another file - windows

Question

I am trying to create a batch file which will read from a file and store the text in a variable. Later this variable has to be replaced in another XML file as explained below
Loop thru the Inputfile by reading line by line i.e. one line after the other
Each time replace the file name that has been obtained from above step in payload.xml
Contine with step 2 until end of file is processed. Example input and output is given below
REM Example Input:        D:\Data\somefile.txt
REM 1st Iteration Output:       D:\Data\file1.txt
REM 2nd Iteration Output:       D:\Data\file2.txt
REM and so on
I am trying to do the following but it is not working. Please kindly help.
SETLOCAL EnableDelayedExpansion
Set AllInputFile=D:\AllInputFile\FileList_for_Import.txt
SET INTEXTFILE=C:\myfolder\payload.xml
ECHO "ERRORLEVEL 0-Sucesss else fail " %ERRORLEVEL% " " %AllInputFile%1>>D:\Data\debuginfo.txt2>>D:\Data\debugerr.txt
ECHO "###########Start of MAIN OF LOOP ############"
for /f "tokens=*" %%a in (%AllInputFile%) do (
ECHO "ERRORLEVEL 0-Sucesss else fail " %ERRORLEVEL% " " line=%%a1>>D:\Data\debuginfo.txt2>>D:\Data\debugerr.txt
set "TARG_FILE=%%a"
ECHO "ERRORLEVEL 0-Sucesss else fail " %ERRORLEVEL% " " "TARG_FILE "%TARG_FILE%1>>D:\Data\debuginfo.txt2>>D:\Data\debugerr.txt
REM Get the string and store it in a variable
for /f "tokens=1*delims=:" %%G in ('findstr /n "^" C:\myfolder\payload.xml') do if %%G equ 2 set "DbgLine=%%H"
ECHO "ERRORLEVEL 0-Sucesss else fail " %ERRORLEVEL% " " "DbgLine "%DbgLine%1>>D:\Data\debuginfo.txt2>>D:\Data\debugerr.txt
SET PREVFILE_NM=%DbgLine:~27,-13%
ECHO %PREVFILE_NM%
call set NewDbgLine=%%DbgLine:!PREVFILE_NM!=!TARG_FILE!%%
echo !DbgLine!
ECHO "ERRORLEVEL 0-Sucesss else fail " %ERRORLEVEL% " " "NewDbgLine "!NewDbgLine!1>>D:\Data\debuginfo.txt2>>D:\Data\debugerr.txt
echo "#######################"
set SEARCHTEXT=%DbgLine%
echo "***************"
echo %SEARCHTEXT%
echo "***************"
set REPLACETEXT=%NewDbgLine%
set OUTPUTLINE=
REM Replace the file name
for /f "tokens=1,* delims=¶" %%A in ( '"findstr /n ^^ %INTEXTFILE%"') do (
SET string=%%A
for /f "delims=: tokens=1,*" %%a in ("!string!") do set "string=%%b"
if "!string!" == "" (
echo.>>%OUTTEXTFILE%
) else (
SET modified=!string:%SEARCHTEXT%=%REPLACETEXT%!
echo %modified%
echo !modified! >> %OUTTEXTFILE%
)
)
ECHO "ERRORLEVEL 0-Sucesss else fail " %ERRORLEVEL% " " "End of Main Loop Iteration#######################"1>>D:\Data\debuginfo.txt2>>D:\Data\debugerr.txt
)

When using enabledelayedexpansion and changing variables in a loop
you need to use !variablename! syntax and not %variablename%
