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，我马上就会谈到这一点。
以下是HTML的摘录：
<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>
要达到此目的的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，因为我可以做到
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
时String cellValue = value.getText();
System.out.println(cellValue);
我得到一个空字符串。我正盯着我的电脑屏幕，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。有趣的是有人建议首先点击该值然后尝试getText（）所以当我尝试点击时我得到了例外：
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无法检索文本值，因为它不可见？但是，如果是这种情况，我可以检索诸如类属性，标签等但不是文本值的东西似乎很奇怪。
任何建议都将不胜感激。

答案 0 :(得分：1)
经过多次（大量）故障排除后发现我的Xpath上有一点误。从我的HTML
<div id="QosDashboardPanel0" ...
我没有考虑多个标签。在我的AUT中，我打开了一个新选项卡，而不是新的浏览器选项卡，而是应用程序本身的选项卡，整个Hmtl将保持不变，除了上面的代码段将更改为
<div id="QosDashboardPanel1" ...
我假设身份证不会改变，吸取教训！这就是为什么我遇到'无法点击一个不可见的元素'，该元素实际上存在，但它隐藏在我的活动标签后面。
没有太大的解决方案，但我希望如果有人遇到类似的事情，至少指出它们正确的方向或使钟声响起。
