java 。 Selenium 网络驱动程序。从表格中获取单元格值

Question

这是我的 html 的一部分

<table class="table_results data ajax" data-uniqueId="20605">
  <thead>
  </thead>
  <tbody>
    <tr class="odd">
     <td data-decimals="0" data-type="int" class="right data  not_null  nowrap">1</td>
     <td data-decimals="0" data-type="string" data-originallength="5" class="data  not_null   text ">user1</td>
     <td data-decimals="0" data-type="string" data-originallength="40" class="data  not_null   text ">e38ad214943daad1d64c102faec29de4afe9da3d</td>
     <td data-decimals="0" data-type="string" data-originallength="14" class="data  not_null   text ">user1@mail.com</td>
     <td data-decimals="0" data-type="string" data-originallength="6" class="data  not_null   text ">Smith</td>
     <td data-decimals="0" data-type="string" data-originallength="1" class="data  not_null   text ">&quot;</td>
    </tr>
  </tbody>
</table>

所以我需要的是检索单元格值。另一件事是，当通过浏览器的源代码选项查看代码时，它看起来与上面相同。但是当使用 Firefox 的 firebug 时，它还显示值位于

内

我知道 xPath 就是解决方案。在过去的两个小时里，我尝试了很多方法，但都没有成功。当然，我在 SO 上看到过类似问题的解决方案，但不知何故它们不适合我。

我正在尝试做的事情:

WebElement table_element = driver.findElement(By.xpath("//table//tbody"));
    ArrayList<WebElement> rows = (ArrayList<WebElement>) table_element.findElements(By.tagName("tr"));
    for (WebElement row : rows) {
        ArrayList<WebElement> cells = (ArrayList<WebElement>) row.findElements(By.tagName("//td"));
        for (WebElement cell : cells) {
            System.out.println(cell.getText());
        }
    }
