How can we split string using windows bat - batch-file

Question

How can we split string using windows bat script?
for below .bat code snippet
#echo off & setlocal EnableDelayedExpansion
set j=0
for /f "delims=""" %%i in (config.ini) do (
set /a j+=1
set con!j!=%%i
call set a=%%con!j!%%
echo !a!
(echo !a!|findstr "^#">nul 2>nul && (
rem mkdir !a!
) || (
echo +)
rem for /f "tokens=2" %%k in(config.ini) do echo %%k
)
)
pause
below config file
Q
What's wrong when I del rem at the begin of rem for /f "tokens=2" %%k in(config.ini) do echo %%k
How can I get the /path/to/case and value as a pair?
for /f xxxx in (testconfig.ini) do (set a=/path/to/case1 set b=vaule1)

Answer 1

#ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET "sourcedir=U:\sourcedir"
SET "filename1=%sourcedir%\q43407067.txt"
set j=0
for /f "delims=""" %%i in (%filename1%) do (
set /a j+=1
set con!j!=%%i
call set a=%%con!j!%%
echo !a! SHOULD BE EQUAL TO %%i
(echo !a!|findstr "^#">nul 2>nul && (
echo mkdir !a!
) || (
echo +)
for /f "tokens=2" %%k IN ("%%i") do echo "%%k"
for /f "tokens=1,2" %%j IN ("%%i") do echo "%%j" and "%%k"
)
)
ECHO ----------------------------
SET con
GOTO :EOF
You would need to change the setting of sourcedir to suit your circumstances.
I used a file named q43407067.txt containing your data for my testing.
(These are setting that suit my system)
SO - to address your problems:
because the ) on that line closes the ( on the previous. The ) on that line closes the ( on the one prior. (I changed the rem to an echo so that the code would produce something visible) The first ( on the (echo !a! line is closed by the ) on the line following the (now) two for /f commands. and the ( on the for..%%i..do( is closed by the final ) before the echo -----
You can't delete that ) because it's participating in a parenthesis-pair.
You need a space between the in and the (.
I've shown a way. See for /?|more from the prompt for documentation (or many articles here on SO)
In your code, !a! is the same as %%i - so I've no idea why you are conducting all the gymnastics - doubtless to present a minimal example showing the problem.
Note that since the default delimiters include Space then if any line contains a space in the /path/to/case or value then you'll have to re-engineer the approach.

Answer 2

I' not sure if I understand what exactly it is you need, so what follows may not suit your needs:
#Echo Off
SetLocal EnableDelayedExpansion
Set "n=0"
For /F "Delims=" %%A In (testConfig.ini) Do (Set "_=%%A"
If "!_:~,1!"=="#" (Set/A "n+=1", "i=0"
Echo=MD %%A
Set "con[!n!]!i!=%%A") Else (For /F "Tokens=1-2" %%B In ('Echo=%%A'
) Do (Set/A "i+=1"
Set "con[!n!]!i!=%%B"&&Set/A "i+=1"&&Set "con[!n!]!i!=%%C")))
Set con[
Timeout -1
GoTo :EOF
remove Echo= on line 6 if you are happy with the output and really want to create those directories
