I need regex to control input template 2numbers-space-2letters-space-3numbers

I need regex that controls "00 XX 000 " pattern
please help

private fun isTransferDescriptionValid(description: String): Boolean {
    val regex = "^[a-zA-Z0-9] [a-zA-Z0-9-/,. ][a-zA-Z0-9]\$".toRegex()
    return description.matches(regex)
}

>Solution :

You can use, which would find 00 XX 000

\s is a gensral placeholder for space

val regex = "^[0-9]{2}\s[a-zA-Z]{2}\s[0-9]{3}$".toRegex()

then there is also [:space:]

val regex = "^[0-9]{2}[[:space:]]{1}[a-zA-Z]{2}[[:space:]]{1}[0-9]{3}$".toRegex()

But sometimes only a literal space helps

val regex = "^[0-9]{2} [a-zA-Z]{2} [0-9]{3}$".toRegex()
