Searching dates inside a file with Batch

I want to find some dates inside a file, with Batch.

I have the following code:

SETLOCAL ENABLEDELAYEDEXPANSION
for /F "tokens=*" %%a in (%path%\%file%) do (
    echo %%a | findstr /I "Date:"
 )
ECHO.
PAUSE
PAUSE

With this code I'm able to get the first date that appears in the file, but then the script finishes, and I want to get all the dates presents in the content of the file, not only one.

Do I have to modify the for structure or use another command (instead of findstr)?

If you don't need to use the dates in variables and just want to output them, then just do this at the cli

TYPE "%path%\%file%" | FIND /I "Date:"

If you need to find each date and then do something else with it using a temp variable (and assuming there is only one : in the line with the date, and nothing else follows the date, you could do this in a cmd script

@(SETLOCAL
  ECHO OFF
)

 CALL :Main

( ENDLOCAL
EXIT /b )

:Main
  For /F "Tokens=1* delims=:" %%A IN (`
    TYPE "%path%\%file%" | FIND /I "Date:"
  ') DO (
    REM if you need all the characters after "Date:" we can simply use this next line:
 
    SET "Date_Tmp_Full=%%~B"

    REM. If there may be whitespace around the value after "Date:" we can use the following method instead to trim it instead.

    For /F "tokens=*" %%_ IN ('echo %%~B') DO (
      SET "Date_Tmp=%%~_" )

     REM Your other code can go here, or you can call a function to do more instead.
     REM
     REM
  )
