Question

I have user inputs such as these

paul vs Team Apple Orange
Team Apple Orange vs paul
Team Apple Orange v.s. paul

I need to write a regular expression that detects the words on both sides of the seperator (vs,vs.,v.s.) and store the side with the keyword “team” to variable team and the other to name.

name = "paul"
team = "Apple Orange"

Answer 1

This code will distinguish between the team and the name, allowing you to simple pick it up out of the regular expression match information.

Regex test = new Regex(@"(?i)^(?:(?:Team\s+(?<team>.*?))|(?<name>.*?))(?:\s+(?<vs>v\.?s\.?)\s+)(?:(?:Team\s+(?<team>.*?))|(?<name>.*?))$");
foreach (string input in ...)
{
  Match match = test.Match(input);
  if (match.Success) 
  {
    string team = match.Groups["team"].Value;
    string name = match.Groups["name"].Value;
  }
}
