推荐答案

诀窍是非贪婪的评估:(.*?)

The trick is non-greedy evaluation: (.*?)

class Program
{
    static void Main(string[] args)
    {
        string strInput = @"<a href='someurl.html'><b>need to capture this text</b></a>between '.html'><b>' and '</b></a>";
        var objMatch = Regex.Match(strInput, @"<a\s+href=[\s\S]*?><b>([\s\S]*?)</b></a>");
        if (objMatch.Success)
        {
            Console.WriteLine("Match: {0}", objMatch.Groups[1].Value);
        }
    }
}
