Test, validate and match regular expressions
Matches identifiers made of uppercase letters followed by digits, then two additional underscore-separated uppercase-letter segments, e.g. ABC123_DEF_GHI. The digit sequence is captured in group 1, making it easy to extract an ID or version number. Useful for validating or parsing naming conventions such as Oracle Web ADI interface column identifiers.
