            string str = @"<li><a href=""http://www.itravelqq.com/2011/0407/126739.html"">四五月成高端蜜月游旺季私密</a> <i>[04-0708:41]</i></li><li><a href=""http://www.itravelqq.com/2011/0407/126730.html"">去年10万客赴西</a><i>[04-0708:34]</i></li><li>";

           MatchCollection mc = Regex.Matches(str, @"(?<=href=\""?)([^\""]+)[^\[]+\[([^\]]+)");
           foreach (Match m in mc)
           {
               Console.WriteLine(m.Groups[1]);
               Console.WriteLine(m.Groups[2]);
           }
