我很难检索元素的文本，由于某种原因，WebDriver 可以找到该元素但它无法检索文本，我怀疑是因为由于某种原因该元素对 WebDriver 不可见，我会一会儿就到了。
这是 HTML 的一个片段：
<td id="x-auto-4169" class="x-grid3-col x-grid3-cell x-grid3-td-badCalls " style="width:53px;" role="gridcell">
<div class="x-grid3-cell-inner x-grid3-col-badCalls" unselectable="on">0</div>
</td>
达到此目的的 Xpath 是
String valueXpath = "((//div[@id=\"QosDashpardPanelBottom\"]//div[@id=\"CollectorQoSPerformanceMetricsgrid\"]//div[contains(@class, \"x-grid3-row x-unselectable-single\")])[" + j + "]//div)[" + i + "]";
WebElement value = driver.findElement(By.xpath(valueXpath));
其中“j”是行号，“i”是表格/网格中的列号。我知道 Selenium 可以找到元素，因为我可以
WebElement class = driver.findElement(By.xpath(fullXpath));
String classAttr = arg.getAttribute("class");
我回来了
x-grid3-cell-inner x-grid3-col-badCalls
但是当我尝试
String cellValue = value.getText();
System.out.println(cellValue);
我得到一个空字符串。我盯着我的电脑屏幕，我可以看到值，它是可见的，我知道 Selenium 找到了元素，但我无法检索文本。有趣的是，有人建议先单击该值然后尝试 getText() 所以当我尝试单击时出现异常：
org.openqa.selenium.ElementNotVisibleException: Element is not currently visible and so may not be interacted with
所以我想知道我是否因为不可见而无法检索文本值？但是，如果是这种情况，我可以检索类属性、标签等内容，但不能检索文本值，这似乎很奇怪。
任何建议将不胜感激。
