正则表达式在斜杠之间查找字符串 [英] Regex to find string between slashes

问题描述

我正在尝试编写一个正则表达式(运气不佳)来捕获出现在较大字符串中特定位置的两个斜杠之间的字符串.

I am trying to write a regex (with very little luck) to capture a string that occurs between two slashes in a specific location within a larger string.

一个示例源字符串是:这里会有一些文本描述，后面跟着路径:/XYZ/String-needed/ABC/ETC

An example source string would be: There will be some text description here followed by the path: /XYZ/String-needed/ABC/ETC

所需的字符串总是在第二个和第三个 / 字符之间.

The string-needed will always be between the second and third / character.

此正则表达式的上下文在另一个工具中，但它主要模拟正则表达式使用的 Java 上下文.我知道 / 需要转义 \/ 但我无法获得代码来查找第二个和第三个实例之间的字符串.

The context of regex for this is within another tool, but it models mostly a java context of regex usage. I know that the / will need to be escaped \/ but I cannot get the code to find the string between the second and third instance.

推荐答案

您可以使用以下正则表达式:

You can use following regex :

"^\/[^/]+\/([^/]+)\/"

查看演示 https://regex101.com/r/jR9rV5/1

[^/] 是一个 否定字符类 匹配除 / 之外的任何字符串.

[^/] is a negated character class which match any string except /.
