分成三个空格-批处理脚本 [英] Split by three spaces - batchscript

问题描述

我有一个这样的字符串.

I have a string like this.

adsads   d b c   dsad   ds   ads

如何分割此字符串(在3个空格上)以从该字符串中获得d b c?

How do I split this string (on 3 spaces) to obtain d b c from this string?

推荐答案

@ECHO OFF
SETLOCAL

SET "string=adsads   d b c   dsad   ds   ads"

FOR /f "tokens=1delims=#" %%p IN ("%string:   =#%") DO ECHO token 1 is "%%p"
FOR /f "tokens=2delims=#" %%p IN ("%string:   =#%") DO ECHO token 2 is "%%p"
FOR /f "tokens=3delims=#" %%p IN ("%string:   =#%") DO ECHO token 3 is "%%p"
FOR /f "tokens=1,3delims=#" %%p IN ("%string:   =#%") DO ECHO token 1 is "%%p"; token 3 is "%%q"
GOTO :EOF

在这里，for /f解析提供的字符串(用引号引起来)，并将指定的令牌编号分配给%%p(如果%%q，%%r指定了多个 token ...)

Here, for /f parses the string supplied (in quotes) and assigns the nominated token number to %%p (and if more than 1 token is specified to %%q, %%r...)

引号之间的字符串是通过用#替换 Space Space Space 构造的-#是一个否则不会出现的字符出现在字符串中.

The string between the quotes is constructed by substituting # for SpaceSpaceSpace - # being a character that doesn't otherwise occur in the string.
