正则表达式在第二个和第三个斜杠之间查找文本 [英] Regex to find text between second and third slashes

问题描述

我想捕获字符串中出现在第二个斜杠之后和第三个斜杠之前的文本.示例:

I would like to capture the text that occurs after the second slash and before the third slash in a string. Example:

/ipaddress/databasename/

/ipaddress/databasename/

我只需要捕获数据库名称.数据库名称可能包含字母、数字和下划线.谢谢.

I need to capture only the database name. The database name might have letters, numbers, and underscores. Thanks.

推荐答案

您如何访问它取决于您的语言，但您基本上只需要一个捕获组来处理您的第二个和第三个/"之间的任何内容.假设您的字符串始终与您的示例格式相同，这将是:

How you access it depends on your language, but you'll basically just want a capture group for whatever falls between your second and third "/". Assuming your string is always in the same form as your example, this will be:

/.*/(.*)/

如果可以存在多个斜杠，但数据库名称中永远不能存在斜杠，您需要:

If multiple slashes can exist, but a slash can never exist in the database name, you'd want:

/.*/(.*?)/
