在Windows Batch中以可变长度分割字符串 [英] Split string with variable length in Windows Batch

问题描述

我实际上正在编写代码/解码器.现在，我必须将数字组与其他组分开.数字组的长度是未知的，但我知道它们会被"(空格字符)除.我不知道如何进行，但是我可以用伪代码解释我的遗嘱:

I'm actually working on a codifier/decodifier. Now I have to separate numeric groups from others. The length of the numeric groups is unknown but I know they are divided by " " (a space char). I don't know how to proceed, but I can explain my will with a pseudo-code:

for x-times (maybe the maximum, like 128) (
group[index] = the first part of the string until " "
string = string minus the first part until " "
)

基本上，我想将组提取到单个数组中.这可能吗?我尝试了很多使用已定义标记的方法，但是我的系统却完全不同.

Basically, I want to extract the groups in a single array. Is this possible? I tried a lot of methods with defined tokens, but my system is completely different.

推荐答案

正如Mofi已经指出的那样，简单的 for 就能解决问题.添加一个计数器以为每个单词"(数组)建立一个变量.它们是实词还是数字都没有关系，但是某些特殊字符会产生错误，例如& ， | 或被忽略，例如％，！).

As Mofi already noted, a simple for will do the trick. Add a counter to build up a variable for every "word" (array). Whether they are real words or numbers doesn't matter, but some special chars will generate errors, like &, | or just being ignored, like %, !).

@echo off
setlocal enabledelayedexpansion
set count=0
set "string=some substrings with variable lengths separated by space"
for %%a in (%string%) do (
  set /a count+=1
  set substring[!count!]=%%a
)
set substring[
