最后一点分了，求一正则表达式

Question

在一个table里有可能又嵌套了table，要求取出最外层的所有行的数组。
如第一个就应该是
<tr>
                <td style="width: 174px">
                    a</td>
                <td>
                    n</td>
                <td>
                    l</td>
            </tr>示例Table：<table border="1" style="width: 557px">
            <tr>
                <td style="width: 174px">
                    a</td>
                <td>
                    n</td>
                <td>
                    l</td>
            </tr>
            <tr>
                <td style="width: 174px">
                    <table border="1" style="width: 139px">
                        <tr>
                            <td style="height: 21px">
                            </td>
                            <td style="height: 21px">
                            </td>
                            <td style="height: 21px">
                            </td>
                        </tr>
                        <tr>
                            <td>
                            </td>
                            <td>
                                d</td>
                            <td>
                            </td>
                        </tr>
                        <tr>
                            <td>
                            </td>
                            <td>
                            </td>
                            <td>
                            </td>
                        </tr>
                    </table>
                </td>
                <td>
                </td>
                <td>
                    <table border="1" style="width: 156px">
                        <tr>
                            <td>
                            </td>
                            <td>
                            </td>
                            <td>
                            </td>
                        </tr>
                        <tr>
                            <td>
                            </td>
                            <td>
                                dd</td>
                            <td>
                            </td>
                        </tr>
                        <tr>
                            <td>
                            </td>
                            <td>
                            </td>
                            <td>
                            </td>
                        </tr>
                    </table>
                </td>
            </tr>
            <tr>
                <td style="width: 174px">
                </td>
                <td>
                </td>
                <td>
                </td>
            </tr>
        </table>

Answer 1

楼主:正则表达式跟你写的Table有什么联系????看不明白！

Answer 2

这个只能通过程序解决吧,设定int i=0和 string str,读取<table时i+1,并且str开始记录（具体的还需要去掉<table >的内容）；</table>读取时i-1,当i=0时str就是你要的。
基本思路就是这样把

Answer 3

hy_lihuan的思路不错，这样应该可以出来。我可以试试。
不过如果正则可以解决那是再好不过了。

Answer 4

表达式:
<tr[^>]*>(?:(?:\s|\S)*?(?=<table|</tr>)(?(<table)<table[^>]*>(?:\s|\S)*?(?:</table>|(?:(?:<table[^>]*>(?:\s|\S)*?</table>(?:\s|\S)*?)*?</table>))(?:\s|\S)*?|))*</tr>一条表达式就可以获取你想要的
写得好辛苦
测试:<table width="300" border="1" cellspacing="0" cellpadding="0">
  <tr>
    <td>&nbsp;</td>
    <td><table width="100%" border="1" cellspacing="0" cellpadding="0">
      <tr>
        <td>&nbsp;</td>
        </tr>    </table>
      <table width="100%" border="1" cellspacing="0" cellpadding="0">

          <td>&nbsp;</td>
        </tr>
      </table></td>
    <td>&nbsp;</td>

      <tr>
        <td>&nbsp;</td>
        </tr>    </table></td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
  </tr>
</table>-------------------获取3个match

简直太佩服了，超级佩服，我得好好学学。
不好意思，CSDN首页不知道有什么特殊的字，被我们公司防火墙屏蔽掉了，今天才知道可以直接敲论坛地址。再次谢谢
