Email addresses accommodate subdomains and different domain formats, including various TLDs. The IDs follow a specific format, and dates are captured in different formats (YYYY-MM-DD, DD/MM/YYYY, and MM.DD.YYYY). All patterns ensure that only the desired items are matched without including any additional unwanted text.
