用于解析目录和文件名的正则表达式 [英] Regex for parsing directory and filename

问题描述

我正在尝试编写一个正则表达式，以使用匹配组来解析完全限定路径的目录和文件名.

I'm trying to write a regex that will parse out the directory and filename of a fully qualified path using matching groups.

所以...

/var/log/xyz/10032008.log

将识别group 1 to be "/var/log/xyz"和group 2 to be "10032008.log"

看起来很简单，但我无法让匹配的小组在我的一生中工作.

Seems simple but I can't get the matching groups to work for the life of me.

注意:正如一些受访者所指出的那样，这可能不是正则表达式的好用法.通常，我更喜欢使用我使用的语言的文件API.我实际上想做的事情比这要复杂一些，但要解释起来要困难得多，所以我选择了每个人都熟悉的领域，以便最简洁地描述根本问题.

NOTE: As pointed out by some of the respondents this is probably not a good use of regular expressions. Generally I'd prefer to use the file API of the language I was using. What I'm actually trying to do is a little more complicated than this but would have been much more difficult to explain, so I chose a domain that everyone would be familiar with in order to most succinctly describe the root problem.

推荐答案

尝试一下:

^(.+)\/([^/]+)$

转义斜线转义以防止在复制/粘贴正则表达式时出现问题

escaped the forward slash to prevent problems when copy/pasting the Regex
