Question

Is it possible to copy the value of a group into another one within the regex? Means, I have a text line

   errID   name_of_error: description bla bla

and I use this RE to save all parts of this line

   ^(?'code'[\w\d]{5}) {3}(?'name'[\w\d]+?(?=:)): (?<= )(?'desc'.+?)(?=$)

What I would have is an additional group in my regex containing the value of ‘code’, like

   code -> errID
   newgroup-> errID
   name-> name_of_error
   desc -> description bla bla

Is it feasible?

EDIT: I’m using C#

I don’t know what language you are using, especially for the syntax of the named groups but I think you can use :

^(?'newgroup'(?'code'[\w\d]{5})) {3}(?'name'[\w\d]+?(?=:)): (?<= )(?'desc'.+?)(?=$)

Moreover [\w\d] can be simplified to \w then the regex becomes:

^(?'newgroup'(?'code'\w{5})) {3}(?'name'\w+?): +(?'desc'.+?)$
