                        <td>
                            值1
                        </td>
</tr>
                    </table>现在想求一个正则表达式，上面的<th>是列头，下面的是值，如何把列头取出来，然后把值对应到列里面，呵呵，谢谢了

Answer 1

(?<=<(\w+).*?>).*(?=<\/\1>)

Answer 2

        string pstr = @"<t(h|d)>(?<c1>[^<]*)</t\1>\s*<t\1>(?<c2>[^<]*)</t\1>\s*<t\1>(?<c3>[^<]*)</t\1>\s*<t\1>(?<c4>[^<]*)</t\1>\s*<t\1>(?<c5>[^<]*)</t\1>";        MatchCollection mc = Regex.Matches(this.TextBox1.Text, pstr, RegexOptions.Singleline);
        for (int i = 0; i < mc.Count; i++)
        {
            Response.Write("c1:" + mc[i].Groups["c1"].Value + "c2:" + mc[i].Groups["c2"].Value + "c3:" + mc[i].Groups["c3"].Value + "c4:" + mc[i].Groups["c4"].Value + "c5:" + mc[i].Groups["c5"].Value + "<br>");
        }

Answer 3

１．确定有多少列
string pstr = "<th>.*?</th>";
int count = Regex.Matches(str, pstr, RegexOptions.Singleline).Count;2.拼接正则pstr = @"<t(h|d)>(?<c1>[^<]*)</t\1>";
for(int i=2;i<=count;i++)
{
pstr += @"\s*<t\1>(?<c" + i.ToString() + @">[^<]*)</t\1>";
}3.匹配        MatchCollection mc = Regex.Matches(str, pstr, RegexOptions.Singleline);
        for (int i = 0; i < mc.Count; i++)
        {
for(int i=1;i<=count;i++)
{
Response.Write("c"+i.ToString() + ":" + mc[i].Groups["c"+i.ToString()].Value);
}
}

Answer 4

如果你的数据都没漏掉的，可以这样。
我没判断是否出现某行不足的情况。        private static void TestRegex26()
        {
            string html = @"<table id=""tbcontent"" class=""class1"" bordercolor=""#C0DE98"" border=""1"">
  <tr>
  <th>
  列头1
  </th>
  <th>
  列头2
  </th>
  <th>
  列头3
  </th>
  <th>
  列头4
  </th>
  <th>
  列头5
  </th>
  
  </tr>
  <tr>
  <td>
  值1
  </td>
  <td>
  值1
  </td>
  <td>
  值1
  </td>
  <td>
  值1
  </td>
  <td>
  值1
  </td>   
  </tr>
  <tr> <td>
  值1
  </td>
  <td>
  值1
  </td>
  <td>
  值1
  </td>
  <td>
  值1
  </td>
  <td>
  值1
  </td>
</tr>
  </table>";
            Match m = Regex.Match(html, @"(?isn)(\s*<th>\W+(?<column>\w+?)\W+</th>)+\s*?</tr>.+?(?<row><tr>(\s*?<td>\W*(?<item>\w*)\W*?</td>)+\s+?</tr>\s*)+");
            List<string> columns = new List<string>();
            foreach (Capture c in m.Groups["column"].Captures)
            {
                columns.Add(c.Value);
            }
            List<List<string>> rows = new List<List<string>>();
            for (int i = 0; i < m.Groups["row"].Captures.Count; i++)
            {
                List<string> row = new List<string>();
                for (int j = i * columns.Count; j < (i + 1) * columns.Count; j++)
                {
                    row.Add(m.Groups["item"].Captures[j].Value);
                }
                rows.Add(row);
            }
            foreach (string column in columns)
            {
                Console.Write(column + "\t");
            }
            Console.WriteLine();
            foreach (List<string> row in rows)
            {
                foreach (string item in row)
                {
                    Console.Write(item + "\t");
                }
                Console.WriteLine();
            }
        }输出列头1   列头2   列头3   列头4   列头5
值1     值1     值1     值1     值1
值1     值1     值1     值1     值1
