原数据如上。如何从上段代码中提取到热辣新闻后面一个的table中td里的数据？
也就是，eeeeeeeeee,ffffffffffffff,gggggggggggggg,hhhhhhh这些数据？
谢谢~~~~

每人看哦？

[我看你有戏]

你把html代码如实的贴出来

这样会好办一点

贴代码啊

using System.Text;
using System.Text.RegularExpressions;
using System.IO;

string html = "...";//整个html
string result = "";//某个<td class="a">与</td>之间的字符串

MatchCollection mc = Regex.Matches(html, "<td class=\"a\">(?<arr>.+?)</td>", RegexOptions.IgnoreCase);

//注：截取页面中所有<td class="a">与</td>之间的字符串并按顺序存为数组
//判断一下你需要的数据是在数组中的位置然后输入i
result = mc[i].Groups["arr"].Value.Trim();
