Regex non-capturing group

Hallo Community,
does anybody know if Robotframework Core does support Regex with the non-capturing group syntax.

Example:
(?: # some regex expression )

I used a regex construct but it did not work unless I removed the “?:” above.

Does anybody know how to escape this expression?

Hi,

I can tell you that I have some fields and Regex likes this that works well:

VAR    ${period}   From  dd/mm/yyyy at hh:mm to dd/mm/yyyy at hh:mm
${end}    Get Regexp Matches    ${period}    (?<=to )\\d{2}/\\d{2}/\\d{4} at \\d{2}:\\d{2}

Or this:

VAR    ${maildata}    Your temporary code is:1a2b
${code}    Get Regexp Matches    ${maildata}    (?<=Your temporary code is:)(\\w+)

And this get me the intended value (end date-time) or code to work with.
Hope this helps.

Regards.
