Kotlin String.split，当分隔符在引号内时忽略 [英] Kotlin String.split, ignore when delimiter is inside a quote

问题描述

我有一个字符串:

Hi there, "Bananas are, by nature, evil.", Hey there.

我想用逗号分隔字符串作为定界符.如何获取.split方法以忽略引号内的逗号，以便它返回3个字符串而不是5个字符串.

I want to split the string with commas as the delimiter. How do I get the .split method to ignore the comma inside the quotes, so that it returns 3 strings and not 5.

推荐答案

您可以在拆分方法中使用regex

You can use regex in split method

根据此答案，以下正则表达式仅与,标记之外的,匹配

According to this answer the following regex only matches , outside of the " mark

，(?=(?:[^ \] \" [^ \] \") [^ \] $)

因此，请尝试以下代码:

so try this code:

str.split(",(?=(?:[^\\\"]*\\\"[^\\\"]*\\\")*[^\\\"]*\$)".toRegex())
