Test, validate and match regular expressions
This regular expression matches a pipe-delimited string with six fields, capturing text, an intended date-like sequence, a number, a Brazilian CEP (postal code format 12345-678), and more text. It is typically used for parsing structured data exports, such as address lists. Note that the date group uses a character class with quantifiers inside brackets `[]`, which is likely a mistake and won't strictly enforce a date format.
