Regex in kotlin

Issue

I'm trying to use substringBefore() fun with two char ("#" and "&"). How can i use regex for both cahrs? I dont want to do this:

if (myString.contains("&")) {            
    myString.substringBefore("&")    
} else if (myString.contains("#"))
    myString.substringBefore("#")
}

Solution

Finally I've found a way and it is actually easy:

 val matchRegex = "[#&]".toRegex().find(myString)
 val manipulatedString = matchRegex?.range?.first?.let {
   myString.substring(0, it)
 }

This will return NULL if there is no regex chars in the string or, the subString before those chars
