Test, validate and match regular expressions
This regex is designed to match the specific Dutch IBAN "NL34RABO0300004826" case-insensitively. It uniquely allows for optional whitespace between every single character, which helps in detecting the account number even if it is obfuscated or spaced out. It is typically used in data loss prevention (DLP) or text mining to identify this exact financial identifier.
