[RESOLVED] Regular Expression help

[stlaural]

Hey motil, here's a good way to do it, I did it in C# as your code sample seemed to be in C#:

private void button1_Click(object sender, EventArgs e)
        {
            string s = "[PlayerID=12345]";
            Regex patern = new Regex(@"\[(PlayerID=(\d+))\]");
            MatchEvaluator matchEval = new MatchEvaluator(GetReplacement);
 
            s = patern.Replace(s,GetReplacement);
 
            MessageBox.Show(s);
 
        }
 
        private string GetReplacement(Match m)
        {
            return "<a href='somestaticwebaddress?" + m.Groups[1] + "'>" + m.Groups[2] + "</a>";
        }

Basically in m.Groups[0] you get the complete match, in Groups[1] and Groups[2] you get the part of the match that are placed in parenthesis in the declared patern. Have a look at the MSDN page on MatchEvaluator, its very useful when it comes to using RegEx to replace values.

EDIT : I should've used StringBuilder in GetReplacement instead of concatenation operators.

Have fun with the RegEx !
