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 中会有很多这样的标签。
<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>

</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,但没有得到第二个,我没有得到第二个 td 元素。
//td[text() = ' Color Digest ']/following-sibling::td[2]
当我将它更改为 td[2] 到 td[1] 时,我得到了这两个元素。
