我有以下HTML结构:我想建立一个可靠的方法来提取第二颜色消化因素,因为会有很多的DOM中的这些标签。
<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>

</table>
我试图提取第二“色彩大师” TD具有解码值的元素。
我写了下面的XPath而是获得第二我没有得到第二个TD元素。
//td[text() = ' Color Digest ']/following-sibling::td[2]
当我将其更改为TD [2] TD [1],我得到两个元素。
