Example

TXT_Résultat is string
// On définit la chaîne à tester et le format qu'elle devrait respecter.
sChaîne is string = "28/03/2003"
sFormatDate is string = "([0-9]+)/([0-9]+)/([0-9]+)"
// Variables pour récupérer les différentes parties du format. 
sJour is string
sMois is string
sAnnée is string
// Si la chaîne vérifie le format alors on affiche ses différentes parties.
IF RegexMatch(sChaîne, sFormatDate, sJour, sMois, sAnnée) THEN
 	TXT_Résultat = "Jours: " + sJour
 	TXT_Résultat += CR + "Mois: " + sMois
 	TXT_Résultat += CR + "Année: " + sAnnée
 END

// Vérification sans tenir compte de la casse
IF RegexMatch(SAI_IMMAT, "(?i)[A-Z]{2}[-][0-9]{3}[-][A-Z]{2}") THEN
...
END

MonEmail is string = "monemail@provider.com"
// Email: vérification de la validité d'un email
IF RegexMatch(MonEmail, "^((?!\.)[\w\-_.]*[^.])(@\w+)(\.\w+(\.\w+)?[^.\W])$") THEN
	Trace("L'email est syntaxiquement correct.")
END

// Mot de passe: vérification de la complexité d'un mot de passe
IF RegexMatch("MotDePasse$1", "^(?=.*[A-Z])(?=.*[a-z])(?=.*\d)(?=.*[^\w\s]).{8,}$") THEN
	Trace("Le mot de passe est fort.")
	// La chaîne contient: 
	// * Au moins 8 caractères, au moins 1 chiffre
	// * Au moins 1 majuscule, au moins 1 minuscule
	// * Au moins 1 caractère spécial
END

// Nombre: vérification permettant de savoir si la chaîne contient un nombre
IF RegexMatch("1.618033", "[-+]?[0-9]*\.?[0-9]*") THEN
	Trace("La chaîne est un nombre entier ou décimal.")
END

// Vérification d'une adresse IP
IF RegexMatch("192.168.100.1", "^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$") THEN
