This regex pattern is designed to match specific XML-like structures, a versioning format, an ISO 8601 timestamp, a URL, a JWT-like string, a feature commit ID, a product identifier, and a specific ISBN format. Each item has been analyzed for its structure, and the necessary escape sequences have been added for characters like angle brackets and periods. The pattern uses alternation (|) to ensure that only the specified items will be matched exactly without capturing any similar invalid patterns in the provided examples.
