XPath ::获取以下兄弟姐妹

Question

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>

我试图提取具有解码值的第二个"颜色摘要"td元素.

我写了下面的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]

当我把它改为td [2]到td [1]时,我得到了两个元素.

Answer 1

您应该寻找具有等于'Color Digest'的td的第二个tr,然后您需要查看tr中第一个td或第二个td的以下兄弟.

请尝试以下方法:

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

要么

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

Answer 2

您可以使用 xPath 识别元素列表：

//td[text() = ' Color Digest ']/following-sibling::td[1]

这将为您提供两个元素的列表，然后您可以将第二个元素用作您想要的元素。例如：

List<WebElement> elements = driver.findElements(By.xpath("//td[text() = ' Color Digest ']/following-sibling::td[1]"))

现在，您可以使用第二个元素作为您想要的元素，即elements.get(1)
