Question

这是我的一段HTML

boolean done = false;

while(!done){
    int counter = 0; // reset counter every time

    for(int i = 0; i < songNums.size(); i++){
        if(number == songNums.get(i).intValue()) {number = r.nextInt(song.size()); counter++;}
    }

    if(counter == 0) done = true;
    else done = false;
}

所以我需要的是检索单元格值。还有一件事是，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，它还会显示值在

之内

<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>

我知道xPath是解决方案。在过去的两个小时里，我尝试了很多，但没有一个有效。当然，我在SO上看到了类似问题的解决方案，但不知怎的，它们不适合我。

我正在尝试做什么：

Answer 2

找到td元素并调用.getText()方法：

List<WebElement> rows = driver.findElements(By.cssSelector("table.table_results tr"));
for (WebElement row: rows) {
    List<WebElement> cells = row.findElements(By.cssSelector("td.data"));
    for (WebElement cell: cells) {
        System.out.println(cell.getText());
    }
}

在这里，我们使用 CSS选择器来查找表行，然后为每个表行搜索行单元格。

Answer 3

List<WebElement> TRCollection = driver.findElement(By.className("table_results data ajax")).findElements(By.tagName("tr"));

for (WebElement tr : TRCollection) 
{
   List<WebElement> TDCollection = tr.findElements(By.tagName("td"));
   for (WebElement td: TDCollection) 
   {
      System.out.println(td.getText());
   }
}

尝试通过以下方式找到您的表：

List<WebElement> tables = driver.findElements(By.tagName("table"));

调试它并找到你的表后，你可以执行上面的代码：

例如......

List<WebElement> TRCollection = tables[2].findElements(By.tagName("tr"));

Answer 4

为了补充以前的awnser，如果你需要从特定行获取文本，你可以这样做：

string userName = "user1";
WebElement row = driver.findElement(By.xPath("//table[contains(@class, 'table_results')]/tbody/tr/td[2][text()='" + userName + "']/.."));

List<WebElement> cells = row.findElements(By.cssSelector("td.data"));
for (WebElement cell: cells) {
    System.out.println(cell.getText());
}

在这种情况下，我使用td[2]来获取行的第二列并比较用户名。如果欲望与其他领域比较，你可以使用它。

此外，您可以断言xpath选择器是否正常工作，或者是否使用chrome控制台返回所需的全部内容：

$x("your xpath selector here")
