如何基于逗号拆分字符串,而不是基于双引号中的逗号

How to split a string based on comma, but not based on comma in double quote

我想根据逗号拆分这个字符串,而不是根据双引号中的逗号 ":

my $str = '1,2,3,"4,5,6"';
.say for $str.split(/','/) # Or use comb?

输出应该是:

1
2
3
"4,5,6"

这可能有帮助:

my $str = ‘1,2,3,"4,5,6",7,8’;

for $str.split(/ \" \d+ % ',' \"/, :v) -> $l {
  if $l.contains('"') {
    say $l.Str;
  } else {
    .say for $l.comb(/\d+/);
  }
}

输出:

1
2
3
"4,5,6"
7
8

使用 comb 的快速解决方案,采取除 ", 之外的任何方法 或带引号的字符串

my $str = '1,2,3,"4,5,6",7,8';
.say for $str.comb: / <-[",]>+ | <["]> ~ <["]>  <-["]>+ / ;

正如@melpomene 建议的那样,使用 Text::CSV 模块也可以。

use Text::CSV;

my $str = '123,456,"78,91",abc,"de,f","ikm"';
for csv(in => csv(in => [$str], sep_char => ",")) -> $arr {
   .say for @$arr;
}

哪个输出:

123
456
78,91
abc
de,f
ikm
