如何遍历字符串中的令牌？ [英] How to loop through tokens in a string?

问题描述

说我有一个字符串，比如foo：条：巴兹，是否可以遍历这个字符串？它看起来像你可以标记化文件的行，但下面将只能随声附和'富'一次。

FOR / F令牌= 1,2 * delims =%%倍In（%% J）做回声%% X

解决方案

 设置字符串= foo的：巴：巴兹
在（％字符串:: =％）做回声%%点¯x%%点¯x
 

有关值分隔符可以是空格，逗号，分号和等号。如果元素与任何字符分隔您可以直接处理的字符串。如果没有，只是改变的分隔符，这些字符中的一个（正如我上面一样）。

 组字符串= foo的酒吧，巴兹;一种=两个
在%% X（％字符串％）做回声%%点¯x
 

Say I have a string such as foo:bar:baz, is it possible to loop through this string? It looked like you could tokenize lines of a file but the following will only echo 'foo' once.

for /f "tokens=1,2* delims=:" %%x in ("%%j") do echo %%x

解决方案

set string=foo:bar:baz
for %%x in (%string::= %) do echo %%x

FOR value delimiters may be space, comma, semicolon and equal-sign. You may directly process a string if the elements are delimited with any of these characters. If not, just change the delimiter for one of these character (as I did above).

set string=foo bar,baz;one=two
for %%x in (%string%) do echo %%x
