'Regex to process multiple entries for a digital signature

I have the regex and corresponding match output here : https://regexr.com/6jiei

Which matches IP and time stamp for all entries currently but I also want the hexadecimal value for identification.

For ex for below Input string:

IDVal 4273E6D162ED2717A1CF4207A254004CD3F5307B
Posted 2022-12-28 07:35:55
Status 2022-12-28 08:10:11
Entry 94.62.86.22 2022-12-28 11:10:30
Entry 21.12.26.23 2022-12-28 13:10:30
Entry 113.132.26.203 2022-12-28 12:56:30
Entry 31.12.27.22 2022-12-28 12:35:30
IDVal 4273E6D162ED2717A1CF4207A254004CD3F5307B
Posted 2022-12-28 07:35:55
Status 2022-12-28 08:10:11
Entry 94.62.86.22 2022-12-28 11:10:30
Entry 21.12.26.23 2022-12-28 13:10:30
Entry 113.132.26.203 2022-12-28 12:56:30
Entry 31.12.27.22 2022-12-28 12:35:30
IDVal 0D12D8E72DED99EE31BB0C57789352BED0CEEEFF
Posted 2022-12-28 07:30:55
Status 2022-12-28 06:10:11
Entry 51.102.52.36 2022-12-28 07:10:30

Output should match/capture :

4273E6D162ED2717A1CF4207A254004CD3F5307B
94.62.86.22 2022-12-28 11:10:30
21.12.26.23 2022-12-28 13:10:30
113.132.26.203 2022-12-28 12:56:30
31.12.27.22 2022-12-28 12:35:30
4273E6D162ED2717A1CF4207A254004CD3F5307B
94.62.86.22 2022-12-28 11:10:30
21.12.26.23 2022-12-28 13:10:30
113.132.26.203 2022-12-28 12:56:30
31.12.27.22 2022-12-28 12:35:30
0D12D8E72DED99EE31BB0C57789352BED0CEEEFF
51.102.52.36 2022-12-28 07:10:30

I tried this regex :

(?s)(\b[A-F\d]{40}\b).*?(\b((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b).?(\b\d{4}(-\d{2}){2} (\d{2}:){2}\d{2}\b)

It then returns the hexadecimal digital signature, but then it only returns the first Entry and doesn't returns all the corresponding entries.

You can start building your query from the back.

Case 1: 4273E6D162ED2717A1CF4207A254004CD3F5307B:

  • multiple alphanumerical characters of length 40, as hinted by your regex attempt: [\w]{40}

Case 2: 113.132.26.203 2022-12-28 12:56:30:

  • a set of numbers and ":": [\d:]+,
  • a space,
  • a set of numbers and "-": [\d-]+
  • a space,
  • a set of numbers and ".": [\d\.]+

Final regex:

"([\w]{40}|[\d\.]+ [\d-]+ [\d:]+)$"

Does it work for you?

================================================================ EDIT: matching with context of the key field

Another option is to check whether Entry or IDVal is at the beginning of the line you need to match:

(?:Entry |IDVal )(.*)

Hence, your code should look like the following:

pattern := '(?:Entry |IDVal )(.*)'
regex   := regexp.MustCompile(pattern)
matches := regex.FindAllStringSubmatch(str1, -1)

The variable matches will contain arrays of length two [[m1,g1], [m2,g2], ... ] where each list will contain the match m<i> and the group g<i>. Your information will be contained inside the corresponding group g<i>.
