I am trying to extract the Second "Color Digest" td element that has the decoded value.
我正在尝试提取具有解码值的第二个“颜色摘要”td 元素。
I wrote the following xpath but instead of getting the second i am not getting the second td element.
我写了下面的 xpath 但我没有得到第二个 td 元素，而不是得到第二个。
//td[text() = ' Color Digest ']/following-sibling::td[2]
And when I change it to td[2] to td[1] I get both the elements.
当我将其更改为 td[2] 到 td[1] 时，我得到了两个元素。

You should be looking for the second tr that has the td that equals ' Color Digest ', then you need to look at either the following sibling of the first td in the tr, or the second td.
您应该寻找具有等于“颜色摘要”的 td 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。
Try the following:
请尝试以下操作：
//tr[td='Color Digest'][2]/td/following-sibling::td[1]
or
或者
//tr[td='Color Digest'][2]/td[2]

You can go for identifying a list of elements with xPath:
您可以使用 xPath 识别元素列表：
//td[text() = ' Color Digest ']/following-sibling::td[1]
This will give you a list of two elements, than you can use the 2nd element as your intended one. For example:
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]"))
Now, you can use the 2nd element as your intended element, which is elements.get(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)

/html/body/table/tbody/tr[9]/td[1]
In Chrome (possible Safari too) you can inspect an element, then right click on the tag you want to get the xpath for, then you can copy the xpath to select that element.
在 Chrome（也可能是 Safari）中，您可以检查一个元素，然后右键单击要获取 xpath 的标签，然后您可以复制 xpath 以选择该元素。
