This problem have an interesting aspect, so I used it to test a different method to process files.

@echo off
setlocal EnableDelayedExpansion

rem Process all .xml files in current directory
for %%a in (*.xml) do (

   rem Locate the line numbers where "CHANGETIME" and "/ENTRIES" appears
   set "insertLine="
   for /F "delims=:" %%b in ('findstr /N "CHANGETIME /ENTRIES" "%%a"') do (
      if not defined insertLine (
         set "insertLine=%%b"
      ) else (
         set "lastLine=%%b"
      )
   )

   rem Block used to read-input-file/create-output-file
   < "%%a" (

           rem Read the first line from input file
           set /P "line="

           rem Copy lines up to the insertion point
           for /L %%i in (1,1,!insertLine!) do set /P "line=!line!" & echo/

           rem Insert the corresponding REMARK file
           type "RemarksFolder\%%a"

           rem Copy the rest of lines
           set /A insertLine+=1
           for /L %%i in (!insertLine!,1,!lastLine!) do set /P "line=!line!" & echo/

           ) > "output.tmp"
   rem Block-end

   rem Replace input file with created output file
   move /Y "output.tmp" "%%a" > NUL

)

This program should run faster than other methods that compare line by line; however, it has the disadvantage that leading spaces are removed from all lines. Although additional code may be inserted in order to fix this point, doing that will slow down the process...
