=== Noncompliant code example

[source,kotlin]
----
if (dateString.matches(Regex("^(?:(?:31(\\/|-|\\.)(?:0?[13578]|1[02]))\\1|(?:(?:29|30)(\\/|-|\\.)(?:0?[13-9]|1[0-2])\\2))(?:(?:1[6-9]|[2-9]\\d)?\\d{2})$|^(?:29(\\/|-|\\.)0?2\\3(?:(?:(?:1[6-9]|[2-9]\\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00))))$|^(?:0?[1-9]|1\\d|2[0-8])(\\/|-|\\.)(?:(?:0?[1-9])|(?:1[0-2]))\\4(?:(?:1[6-9]|[2-9]\\d)?\\d{2})$"))) {
    handleDate(dateString)
}

=== Compliant solution

[source,kotlin]
----
if (dateString.matches(Regex("^\\d{1,2}([-/.])\\d{1,2}\\1\\d{1,4}$"))) {
    val dateParts = dateString.split("[-/.]").toTypedArray()
    val day = dateParts[0].toInt()
    val month = dateParts[1].toInt()
    val year = dateParts[2].toInt()
    // Put logic to validate and process the date based on its integer parts here
}
