Hi @shirin.sebatina

Try this expression to get both the values in single expression

Simple pattern with options:

Advanced with Group Names:

So based on the group name we can retrieve which case we got

Grouped regex

@Poul_Riis it is recommended to use the format button </> from the editor when sharing code snippets. Maybe you are looking for the following: retrieve the information on which group name matched. Variables: [grafik] Flow: [grafik] we init a Regex with the pattern and run the regex: myRegex = new Regex(strPattern) myMatches = myRegex.Matches(strText) Then we do loop the matches and check for all non-empty group members the group name: arrMatchedGroups = (From t In m.Groups.Cast(Of …

Hi @shirin.sebatina ,

Here is an interesting take on this subject, but I guess ppr has beaten me to it!

Basically, you have the option of assigning names to “groups” of matches.

Here is one such example →

regex101: build, test, and debug regex

(?<date>\d+\/\d+\/\d+).*?(?<time>\d+\:\d+\:\d+)

System.Text.RegularExpressions.Regex.Matches(str_DateandTime,"(?<date>\d+\/\d+\/\d+).*?(?<time>\d+\:\d+\:\d+)")

And that allows you to do something amazing like this →

matches.Item(0)
matches.Item(0).Groups("date")
matches.Item(0).Groups("time")

Really beautiful stuff, I’d recommend you give it a try.

Kind Regards,
Ashwin A.K
