My input text is as blow:

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">2</string>

What regex pattern to use to extract the number from the above input?

var pattern = "<string ?>?</string>"; // how to write this?
var match = Regex.Match(input, pattern, RegexOptions.IgnoreCase);

Thanks,

    Another aproach using LinqToXml:

    var ele = XElement.Parse("<string xmlns=\"http://schemas.microsoft.com/2003/10/Serialization/\">2</string>");
var valueString = ele.Value; //valueString = "2";

    Update

    And for regex: I would extend solution from @Oded with (?<=startRegex) and (?=endRegex) (lookbehind and lookahead), so the unnecessary <string> tag will be omitted in match value.

    (?<=<string[^>]+>)([0-9]+)(?=</string>)
