Extract substring between given strings

Given the following string: be_de=Interessant für Dich; be_fr=Intéressant pour toi;

What is the nicest way to extract the substring for a given locale in Kotlin? e.g. I have given the locale be_fr I want to have Intéressant pour toi as a result. The string is always in between the locale followed by a = and a ;

There could be more locales with strings given, and the position of the value to extract always varies.

Of course I could just create a substring after the first index of my locale and then search for the fist index of the semicolon, but I assume there is a more elegant way like using removeSurrounding, which I can't think of atm.

Solution

  • I don't think removeSurrounding applies here, as you can only remove text with that if you know exactly the entire prefix and suffix to remove.

    I'd go with this, as it's very easy to read:

    val result = data.substringAfter("be_fr=").substringBefore(';')
