我有以下HTML struct :我试图构建一个健壮的方法来提取第二个 colored颜色 摘要元素，因为DOM中会有很多这样的标记.
<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try 提取具有解码值的第二个"Color Digest"TD元素.
我编写了以下XPath，但是我没有得到第二个td元素，而是没有得到第二个.
//td[text() = ' Color Digest ']/following-sibling::td[2]
当我把它改为TD[2]到TD[1]时，我得到了这两个元素.
