Question

获取单元格的值这里是我的一块HTML的

<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的值。 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。但使用Firefox的萤火，当另外表明，价值观是

<span></span> 

标签

里面我知道这里XPath是解决方案。在过去的2个小时里，我尝试了很多，但都没有成功。 当然，我也看到类似的问题的解决方案，但不知何故，他们不适合我。

我想要做的事：

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()); 
     } 
    } 

Answer 1

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选择查找表中的行，然后为每个表格行排列单元格。

Answer 2

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()); 
    } 
} 

尝试找到自己的表：

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

调试和找到你的表之后，你可以做上面的代码：

例如像...

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

Answer 3

为了补充以前的awnser，如果需要从特定行中获取文本，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。如果愿望比较其他领域，你可以改变它。

此外，您可以如果XPath选择工作断言或如果它返回所有要使用Chrome控制台：

$x("your xpath selector here")
