XPath:: 获取以下同级

我有以下 HTML 结构：我正在尝试构建一个强大的方法来提取第二个颜色摘要元素，因为 DOM 中会有许多这样的标签。

<table>
  <tbody>
    <tr bgcolor="#AAAAAA">
    <tr>
    <tr>
    <tr>
    <tr>
      <td>Color Digest </td>
      <td>AgArAQICGQMVBBwTIRQHIwg0GUMURAZTBWQJcwV0AoEDAQ </td>
    </tr>
    <tr>
      <td>Color Digest </td>
      <td>2,43,2,25,21,28,0,0,0,0,0,0,0,0,0,0,0,0,0,0,33,7,0,0,0,0,0,0,0,0,0,0,0,0,0,0,8,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,25,0,0,0,0,0,0,0,0,0,0,0,0,0,0,20,6,0,0,0,0,0,0,0,0,0,0,0,0,0,0,5,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,9,0,0,0,0,0,0,0,0,0,0,0,0,0,0,5,2,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, </td>
    </tr>
  </tbody>
</table>

我正在尝试提取具有解码值的第二个“颜色摘要”td 元素。

我编写了以下 xpath 但没有获得第二个，而是没有获得第二个 td 元素。

//td[text() = ' Color Digest ']/following-sibling::td[2]

当我将其更改为 td[2] 到 td[1] 时，我得到了这两个元素。

您应该寻找 td 等于“Color Digest”的第二个 tr，然后您需要查看 tr 中第一个 td 的以下同级，或第二个 td。

请尝试以下操作：

//tr[td='Color Digest'][2]/td/following-sibling::td[1]

or

//tr[td='Color Digest'][2]/td[2]
