下面是一行tablerow的数据，可以分解出来，<td><td>之间是一个cell列。

如何解析第一列的href、class之间的3个数据呢，？、delphi7 滚动条颜色、VCL组件开发及应用

          <tr>
    <td class="title">
      <strong class="green">？</strong>
      <a href="/topics/390861446" target="_blank" title="delphi7 滚动条颜色">delphi7 滚动条颜色</a>
      <span class="forum_link">[<span class="parent"><a href="/forums/Delphi">Delphi</a></span> <a href="/forums/DelphiVCL">VCL组件开发及应用</a>]</span>
    </td>
    <td class="tc">20</td>
    <td class="tc">
      <a href="http://my.csdn.net/u010745617" rel="nofollow" target="_blank">u010745617</a><br />
      <span class="time">08-15 16:25</span></td>
    <td class="tc">1</td>
    <td class="tc">
