使用管道转义匹配管道分隔字符串的正则表达式 [英] regular expression to match pipe separated strings with pipe escaping

问题描述

我想获得管道分隔字符串的单个字符串，支持管道转义"，例如:

I'd like to get the single strings of a pipe-separated string, with "pipe escaping" support, e.g.:

fielda|field b |field\|with\|pipe\|inside

会让我:

array("fielda", "field b ", "field|with|pipe|inside")

我如何使用正则表达式达到这个目标?

How would I reach that goal with a regular expression?

推荐答案

Split  by this (?<!\\)\|

查看演示.后视确保 | 不在 \ 之后.

See demo.The lookbehind makes sure | is not after \.
