我要怎么得出
2012-12-05 2012120505 08 02 12 11 14 05 17 20
2012-12-05 2012120506 03 18 17 08 04 12 09 01
2012-12-05 2012120507 20 18 05 02 13 14 10 17
以下类推

Answer 1

完全是体力活啊<tr class=".*">[\s]+<td class=".*">([\w\W]+?)</td>[\s]+<td class=".*">[\s]+([\d]+)[\s]+</td>[\s]+<td class=".*"><span class="result">[\s]+<span class="ball_1">([\d]+)</span>[\s]+<span class="ball_1">([\d]+)</span>[\s]+<span class="ball_1">([\d]+)</span>[\s]+<span class="ball_1">([\d]+)</span>[\s]+<span class="ball_1">([\d]+)</span>[\s]+<span class="ball_1">([\d]+)</span>[\s]+<span class="ball_1">([\d]+)</span>[\s]+<span class="ball_1">([\d]+)</span>[\s]+</span></td>[\s]+<td class=".*">0</td>[\s]+</tr>

Answer 2

亲，把那个当成XML加载分析不更好使？正则看起来比较技术流，不过累啊

Answer 3

            string str = File.ReadAllText(@"E:\text.txt");
            Regex regex = new Regex(@"<td[^>]*""td1"">(?<D1>[0-9-]*)</td>\s*<td[^>]*td2"">\s*(?<D2>\d*)\s*</td>[\s\S]*(?<start><span[^>]*>)(?<D3>\d*)(?<end></span>)\s*\k<start>(?<D4>\d*)\k<end>\s*\k<start>(?<D5>\d*)\k<end>\s*\k<start>(?<D6>\d*)\k<end>\s*\k<start>(?<D7>\d*)\k<end>\s*\k<start>(?<D8>\d*)\k<end>\s*\k<start>(?<D9>\d*)\k<end>\s*\k<start>(?<D10>\d*)\k<end>");            MatchCollection mc = regex.Matches(str);            foreach (Match match in mc)
            {
                Console.WriteLine(string.Concat(match.Groups["D1"], " ", match.Groups["D2"]), " ", match.Groups["D3"], " ", match.Groups["D4"], " ", match.Groups["D5"], " ", match.Groups["D6"], " ", match.Groups["D7"], " ", match.Groups["D8"]);
            }
            Console.Read();

Answer 4

有点问题，现修改如下：        static void Main(string[] args)
        {
            string str = File.ReadAllText(@"E:\text.txt");
            Regex regex = new Regex(@"<td[^>]*""td1"">(?<D1>[0-9-]*)</td>\s*<td[^>]*td2"">\s*(?<D2>\d*)\s*</td>\s*<td[^>]*""><span[^>]*>\s*(?<start><span[^>]*>)(?<D3>\d*)(?<end></span>)\s*\k<start>(?<D4>\d*)\k<end>\s*\k<start>(?<D5>\d*)\k<end>\s*\k<start>(?<D6>\d*)\k<end>\s*\k<start>(?<D7>\d*)\k<end>\s*\k<start>(?<D8>\d*)\k<end>\s*\k<start>(?<D9>\d*)\k<end>\s*\k<start>(?<D10>\d*)\k<end>");            MatchCollection mc = regex.Matches(str);            foreach (Match match in mc)
            {
                Console.WriteLine(string.Concat(match.Groups["D1"].Value, " ", match.Groups["D2"], " ", match.Groups["D3"], " ", match.Groups["D4"], " ", match.Groups["D5"], " ", match.Groups["D6"], " ", match.Groups["D7"], " ", match.Groups["D8"], " ", match.Groups["D9"], " ", match.Groups["D10"]));
            }
            Console.Read();
        }
效果如下图所示
