How to split a string by spaces in a Windows batch file?
提问by Cheeso
Suppose I have a string "AAA BBB CCC DDD EEE FFF".
假设我有一个字符串“AAA BBB CCC DDD EEE FFF”。
How can I split the string and retrieve the nth substring, in a batch file?
如何在批处理文件中拆分字符串并检索第 n 个子字符串？
The equivalent in C# would be
C# 中的等价物是
"AAA BBB CCC DDD EEE FFF".Split()[n]

Three possible solutions to iterate through the words of the string:
遍历字符串单词的三种可能解决方案：
Version 1:
版本 1：
@echo off & setlocal
set s=AAA BBB CCC DDD EEE FFF
for %%a in (%s%) do echo %%a
Version 2:
版本 2：
@echo off & setlocal
set s=AAA BBB CCC DDD EEE FFF
set t=%s%
:loop
for /f "tokens=1*" %%a in ("%t%") do (
echo %%a
set t=%%b
)
if defined t goto :loop
Version 3:
版本 3：
@echo off & setlocal
set s=AAA BBB CCC DDD EEE FFF
call :sub1 %s%
exit /b
:sub1
if "%1"=="" exit /b
echo %1
shift
goto :sub1
Version 1 does not work when the string contains wildcard characters like '*' or '?'.
当字符串包含“*”或“?”等通配符时，版本 1 不起作用。
Versions 1 and 3 treat characters like '=', ';' or ',' as word separators. These characters have the same effect as the space character.
版本 1 和 3 处理像“=”、“;”这样的字符 或 ',' 作为单词分隔符。这些字符与空格字符具有相同的效果。

This is the only code that worked for me:
这是唯一对我有用的代码：
for /f "tokens=4" %%G IN ("aaa bbb ccc ddd eee fff") DO echo %%G
output:
输出：
ddd

The following code will split a string with an arbitrary number of substrings:
以下代码将拆分具有任意数量子字符串的字符串：
@echo off
setlocal ENABLEDELAYEDEXPANSION
REM Set a string with an arbitrary number of substrings separated by semi colons
set teststring=The;rain;in;spain
REM Do something with each substring
:stringLOOP
REM Stop when the string is empty
if "!teststring!" EQU "" goto END
for /f "delims=;" %%a in ("!teststring!") do set substring=%%a
REM Do something with the substring -
REM we just echo it for the purposes of demo
echo !substring!
REM Now strip off the leading substring
:striploop
set stripchar=!teststring:~0,1!
set teststring=!teststring:~1!
if "!teststring!" EQU "" goto stringloop
if "!stripchar!" NEQ ";" goto striploop
goto stringloop
)
:END
endlocal

The following code will split a string with N number of substrings with # separated values. You can use any delimiter
以下代码将拆分一个字符串，其中包含 N 个子字符串，其中包含 # 个分隔值。您可以使用任何分隔符
@echo off
if "%1" == "" goto error1
set _myvar="%1"
:FORLOOP
For /F "tokens=1* delims=#" %%A IN (%_myvar%) DO (
echo %%A
set _myvar="%%B"
if NOT "%_myvar%"=="" goto FORLOOP
)
goto endofprogram
:error1
echo You must provide Argument with # separated
goto endofprogram
:endofprogram

If someone need to split a string with any delimiter and store values in separate variables, here is the script I built,
如果有人需要用任何分隔符拆分字符串并将值存储在单独的变量中，这是我构建的脚本，
FOR /F "tokens=1,2 delims=x" %i in ("1920x1080") do (
set w=%i
set h=%j
)
echo %w%
echo %h%
Explanation: 'tokens' defines what elements you need to pass to the body of FOR, with token delimited by character 'x'. So after delimiting, the first and second token are passed to the body. In the body %i refers to first token and %j refers to second token. We can take %k to refer to 3rd token and so on..
说明：'tokens' 定义了需要传递给 FOR 主体的元素，标记由字符 'x' 分隔。所以在定界之后，第一个和第二个标记被传递给正文。在正文中，%i 指的是第一个标记，而 %j 指的是第二个标记。我们可以用 %k 来指代第三个令牌等等..

set a=AAA BBB CCC DDD EEE FFF
set a=%a:~6,1%
This code finds the 5th character in the string. If I wanted to find the 9th string, I would replace the 6 with 10 (add one).
此代码查找字符串中的第 5 个字符。如果我想找到第 9 个字符串，我会将 6 替换为 10（加一个）。

I ended up with the following:
我最终得到了以下结果：
set input=AAA BBB CCC DDD EEE FFF
set nth=4
for /F "tokens=%nth% delims= " %%a in ("%input%") do set nthstring=%%a
echo %nthstring%
With this you can parameterize the input and index. Make sure to put this code in a bat file.
有了这个，您可以参数化输入和索引。确保将此代码放在 bat 文件中。
