Hey all,
I'm trying to do a regexp that will gracefully extract the fields (fn)
from a string in this format:
(f1, f2, f3),(f1, f2, f3),(f1, f2, f3),...,(f1, f2, f3)
Is there a way I could grab each (f1, f2, f3) and then iterate through
them gracefully. I'm using Split(str, ",\)") , but then I have to remove
the ('s and )'s from the beginning and end of the first and last () set.
It's not a big deal, it's just ugly.
Can't I do a regexp like "\(.*\)", and iterate through every match in a
string of indeterminate length?
Thanks,
Eric 2 1106

Eric,
Yes you can. Use \((?<content>.*?)\) to get 1-N capture groups named
"content". Each group will contain f1, f2, f3 (without the
parentheses).

Hope this helps.

Perfect, I eventually came up with (well, sort of) this:
Dim inputStr As String = "(f1, f2, f3), (f4, f5, f6)"
Dim inputStrFlds As String()
Dim msg As String
Dim Regexp as Regex = New Regex("\((?<content>.*,.*,.*?)\)",
RegexOptions.IgnoreCase)
Dim objMatch as Match
If inputStr.Length > 0 Then
'Create a Match object instance / iterate through the MatchCollection
For Each objMatch in Regexp.Matches(inputStr)
inputStrFlds = Split(objMatch.Groups("content").Value, ",")
If UBound(inputStrFlds) <> 0 Then
Response.Write(inputStrFlds(0) & " and " & inputStrFlds(1) & _
" and " & invalidFlds(2) & "<br>")
End If
Next
End If
Thanks!
