java - 当表呈指数减少时，如何仅迭代每行的最后一列数据

Question

我有一个包含 tr 和 td 的 HTML 表。这些值根据给定的日期选择进行更改。我需要迭代每一行、最后一列数据并添加它们。每行该值减一。请帮助我，如何仅获取每行的最后一列数据。该图像附在下面并突出显示。

如果您看到上图，这些值呈指数递减，甚至元素标签也发生变化，如 cornelius-low、cornelius-high、cornelius-medium 等。

我尝试了下面的代码保持循环。由于元素标签发生变化，无法仅获取 0, 7186, 33790, 14839, 226

Answer 1

尝试使用以下代码获取每个tr的最后一个td:

List<WebElement> rows = driver.findelements(By.xpath('//table[@class="cornelius-table"]//tr[not(th)]'));
Iterator<WebElement> iter = rows.iterator();
while(iter.hasNext()) {
    WebElement tr = iter.next();
    td = tr.findelement(By.xpath('./td[not(@class="cornelius-empty")][last()]'));
    System.out.println(td.getText());
    }
}
