在指定字符后使用 RegEx 匹配序列 [英] Match Sequence using RegEx After a Specified Character

问题描述

初始字符串是[image:salmon-v5-09-14-2011.jpg]

我想捕获文本salmon-v5-09-14-2011.jpg"并使用 GSkinner 的 RegEx 工具

I would like to capture the text "salmon-v5-09-14-2011.jpg" and used GSkinner's RegEx Tool

最接近我想要的输出的是使用这个 RegEx:

The closest I can get to my desired output is using this RegEx:

:([\w+.-]+)

问题是这个序列包含冒号，输出变成了

The problem is that this sequence includes the colon and the output becomes

:salmon-v5-09-14-2011.jpg

如何在没有冒号的情况下捕获所需的输出.感谢您的帮助！

How can I capture the desired output without the colon. Thanks for the help!

推荐答案

使用回顾:

(?<=:)[\w+.-]+

后视(编码为 (?<=someregex))是零宽度匹配，因此它断言但不捕获匹配.

A look-behind (coded as (?<=someregex)) is a zero-width match, so it asserts, but does not capture, the match.

此外，您的正则表达式可以简化为:

Also, your regex may be able to be simplified to this:

(?<=:)[^\]]+

它只是抓取(但不包括): 和 ]

which simply grabs anything between (but not including) a : and a ]
