You can group patterns inside the regx and get those from the match

var    match= Regex.Match(item.Value, @"\/>(?<groupName>.*)?\*>", RegexOptions.IgnoreCase);
 var data= match.Groups["groupName"].Value

You can also use look-ahead and look-behind. For your example it would be:

var value = Regex.Match(@"(?<=\/>).*?(?=\*>)").Value;

You can save parts of the regex by putting ()'s around the area. so for your example:

// item.Value ==  "/>test*>"
Match m = Regex.Match(item.Value, @"\/>(.*?)\*>");
Console.WriteLine(m.Groups[0].Value); // prints the entire match, "/>test*>"
Console.WriteLine(m.Groups[1].Value); // prints the first saved group, "test*"

I also removed RegexOptions.IgnoreCase because we aren't dealing with any letters specifically, whats an uppercase /> look like? :)
