正则表达式在两个特定正斜杠之间提取字符串

Hi I have the following text:

file:/home/dx/reader/validation-garage/IDON/test-test-test@2016-10-04.txt#/

I need to retrieve test-test-test@2016-10-04.txt# from the string above. If I can also exclude the hash even better.

I've tried looking at examples like this Regex to find text between second and third slashes but having trouble getting it working, can anyone help?

I'm using PHP regex to do this.

    You may try regex expression below

    \/([a-z\-]*\@[0-9\-\.]*[a-z]{3}\#)\/
    

    A working example is here: https://www.regex101.com/r/RYsh7H/1

    Explanation:

    [a-z\-]* => Matches test-test-test part with lowercase and can contain dahses
    \@ => Matches constant @ sign
    [0-9\-\.]* => Matches the file name with digits, dashes and {dot}
    [a-z]{3}\# => Matches your 3 letter extension and #
    

    PS: If you really do not need # you do not have to use regex. And you may consider using parse_url method of PHP.

    Hope this helps;
