Test, validate and match regular expressions
This regular expression validates a simplified ISO 8601 datetime format, strictly checking for strings in the 'YYYY-MM-DDTHH:MM:SS' structure. It uses capture groups for each component (year, month, day, hour, minute, and second) to allow for easy extraction. This pattern is ideal for validating strict datetime strings in logs, APIs, or data processing pipelines where timezone offsets are omitted.
