With regular expressions you can have groups that require a match but aren't captured.  Is there a way to do the inverse: have a group that is captured but does not have to match?  That way a regular expression could dictate bits of text to insert into the result all within a single call to Match().

Thank you for your time,

I have a program where the user enters regular expressions to parse websites.  For example, if the website has something like:

temperature=55

I would use @"temperature=(\d+)" to grab that value.  But what if the user didn't want the output to be:

55

but wanted the output to be:

55°

So is there any way to insert text into the output through the regular expression?  For example, let's say anything between two parentheses with a pound sign (#text) would be inserted into the output but not matched in the regular expression so that the syntax would look like:

@"temperature=(\d+)(#°)"

and output:

55°

Thank you,

I think you can do it via a Regex.Replece method. You will have to write a delegate MatchEvaluator and declare and reference it. The delegate will do anything you want to do.
