Question

Hi 
I want to remove the text inside the xml tags and am failing to do so. i have tried this codding with no results.
<value>yes</value> = <value></value>
<value>yes</value> = <value></value>
<value>yes</value> = <value></value>
my code:
                string text = File.ReadAllText(outputFilePath);
                text = DeleteBetween1(text,"<value>", "</value>");
 public string DeleteBetween(string STR, string FirstString, string LastString)
            string regularExpressionPattern1 = @"(?:\" + FirstString + @")(<^<>+)\<\/" + LastString;
            Regex regex = new Regex(regularExpressionPattern1, RegexOptions.Singleline);
            MatchCollection collection = regex.Matches(STR.ToString());
            var val = string.Empty;
            foreach (Match m in collection)
                val = m.Groups[1].Value;
