how to extract an integer range from a string

Issue

I have a string that contains different ranges and I need to find their value

var str = "some text x = 1..14, y = 2..4 some text" I used the substringBefore() and substringAfter() methodes to get the x and y but I can't find a way to get the values because the numbers could be one or two digits or even negative numbers.

Solution

Is this solution fit for you?

val str = "some text x = 1..14, y = 2..4 some text"    
val result = str.replace(",", "").split(" ")
var x = ""; var y = ""

for (i in 0..result.count()-1) {
    if (result[i] == "x") {
        x = result[i+2]
    } else if (result[i] == "y") {
        y = result[i+2]
    }
}

println(x)
println(y)
