Regular Expressions
Regex101 site (very handy online checker and pretty) Regex Library
IPv4 address example
^((\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.){3}(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])$
IPv6 address examples (hexadecimal formats only)
Long form only:
^([0-9a-fA-F]{4}:){7}[0-9a-fA-F]{4}$
Medium form that allows leading zeros in hextet:
^([0-9a-fA-F]{1,4}:){7}[0-9a-fA-F]{1,4}$
Medium form that does not allow leading zeros in hextet:
^(([0-9a-fA-F]{1}|[1-9a-fA-F]{1}[0-9a-fA-F]{1,3}):){7}([0-9a-fA-F]{1}|[1-9a-fA-F]{1}[0-9a-fA-F]{1,3})$
Some test formats:
0:0:0:0:0:0:0:0 7:6:5:4:3:2:1:0 ffff:ffff:ffff:ffff:FFFF:FFFF:FFFF:FFFF 0fff:ffff:ffff:ffff:FFFF:FFFF:FFFF:FFFF (invalid due to leading 0 in first hextet group)
My regex notes for checking an ASN.1 GeneralizedTime type
General (my wording!)
- ^ means start of string
- () means capture everything inside
- | means or, aka "pipe" key
- [] means single character with rules, rules are inside square brackets
- \d means any digit
- {} means quantity with specified conditions
- ? means zero or one of previous character
- $ means end of string
Regex based on US requirements for time (within 200ms of event time) plus optional Z offset:
^20(19|20)([0][1-9]|[1][0-2])([0][1-9]|[1-2][\d]|[3][0-1])([0-1][\d]|[2][0-4])([0-5][\d])([0-5][\d]).\d{1,3}Z?$
Regex explained
^20(19|20)= string starts with exactly 20 followed by 19 or 20 (match year "YYYY format")([0][1-9]|[1][0-2])= next two characters must match either [0][1-9] or [1][0-2], which means 01-09 or 10-12 (match month "MM format")([0][1-9]|[1-2][\d]|[3][0-1])= next two characters must match either [0][1-9] or [1-2][\d] or [3][0-1], which means 01-09 or 10-29 or 30-31(match day "DD format")([0-1][\d]|[2][0-4])= next two characters must match either [0][\d] or [1][\d] or [2][0-4], which means 00-09 or 10-19 or 20-24 (match hour "HH format" in 24-hour format)([0-5][\d])= next two characters must match [0-5][\d], which means 00-59 (match minutes "MM format")([0-5][\d])= next two characters must match [0-5][\d], which means 00-59 (match minutes "SS format").= next character must be . (period)\d{1,3}= next 1 to 3 characters must be any digit (match milliseconds .f, .ff, .fff format)Z?= next character must be zero or one of Z (capital Z). Zero Z means Z is missing$= end of string (no following characters)
Take examples, like 20190822005901.9Z, 20190801230059.09Z, 20190822005901.991Z, and play around in Regex101 online tool
