得到所有的a标签，然后在筛选吧 href:http://qq.com/nfdsb//content_30711112.htm text:啊啊啊啊啊啊啊啊啊啊啊啊啊

    string tempStr = "<li>• <a href=\"http://qq.com/nfdsb//content_30711112.htm\" target=\"_blank\" mon=\"a=1&p=1&pn=5\">啊啊啊啊啊啊啊啊啊啊啊啊啊</a><span class=\"s\">08:53</span><a href=\"/n?cmd=2&class=shyf&page=http%3A%2F%2Fnf.nfdaily.cn%2Fnfdsb%2Fcontent%2F2011-09%2F30%2Fcontent_30711112.htm&cls=shyf\" target=\"_blank\" class=\"rnews\">47条相关>></a> </li><li>• <a href=\"http://baidu.com/content_30711112.htm\" target=\"_blank\" mon=\"a=1&p=1&pn=5\">噩噩噩噩噩噩噩噩噩噩噩噩噩</a><span class=\"s\">08:53</span><a href=\"/n?cmd=2&class=shyf&page=http%3A%2F%2Fnf.nfdaily.cn%2Fnfdsb%2Fcontent%2F2011-09%2F30%2Fcontent_30711112.htm&cls=shyf\" target=\"_blank\" class=\"rnews\">47条相关>></a> </li>";
            string pattern = @"<a[^>]*href=(""(?<href>[^""]*)""|'(?<href>[^']*)'|(?<href>[^\s>]*))[^>]*>(?<text>[\s\S]*?)</a>";
            MatchCollection mc = Regex.Matches(tempStr, pattern, RegexOptions.Multiline|RegexOptions.IgnoreCase);
            for (int i = 0; i < mc.Count; i++)
            {
                string href = mc[i].Groups["href"].Value;//href
                string text = mc[i].Groups["text"].Value;//得到标签内容
         
            }

            string str = File.ReadAllText(@"E:\1.txt", Encoding.GetEncoding("gb2312"));
            Regex reg = new Regex("(?is)<li[^>]*?>.*?<a[^>]*?>(.*?)</a>");
            foreach (Match m in reg.Matches(str))
                Console.WriteLine(m.Groups[1].Value);
            Regex href = new Regex(@"(?is)<li[^>]*?>.*?<a[^>]*?href=(['""]?)([^'""]+qq[^'""]+)\1[^>]*?>");
            foreach (Match m in href.Matches(str))
                Console.WriteLine(m.Groups[2].Value);

方法同三楼 得到A标签再进行区分 是在JS 中选择吧
那就可以用 jQuery对象获得之后区分

谢谢大家哈！

我用字符串截取做的，刚改下2楼的做法，可行。所以下面的方法就不试了。

给分！！！
