Selenium WebDriver能够定位xpath并对其执行操作，但仍会抛出“NoTouchElementException”

下面是使用xpath单击对象的简单代码。我成功地找到了xpath并执行了所需的操作，但仍然没有抛出任何uchelementException

String localobject=OR.getProperty(object); //Obtaining xpath from object repository
we = driver.findElement(By.xpath(""+localobject+"")); 
executor.executeScript("arguments[0].click();", we);

这是痕迹

org.openqa.selenium.NoSuchElementException: Unable to find element with css selector == #\/\/\*\[text\(\)\=\'Log\ Out\'\]

错误说明了一切：

org.openqa.selenium.NoSuchElementException: Unable to find element with css selector == #\/\/\*\[text\(\)\=\'Log\ Out\'\]
// and
Element info: {Using=id, value=//*[text()='Log Out']}

表达式/*[text\=\'Log\Out\']绝对不是有效的css选择器。当前CSS_选择器不支持文本属性

表达式//*[text='Log Out']不是有效的id，而是一个潜在的xpath

解决方案 从对象存储库获取xpath时，请确保将其作为字符串调用，如下所示：

we = driver.findElement(By.xpath(localobject));

在@DebanjanB的回答中添加：

您也可以尝试将其用作元素定位器-

//*[contains(.,'Log Out')]

试试这个，让我知道它是否适用于您。

我使用了您上面的解决方案，但最终还是出现了相同的情况。我正在以类似的方式对其他xpath执行相同的单击操作，在所有其他情况下都可以正常工作。只有使用这个特定的xpath异常才会引发。我想问题是其他的。还是谢谢你的尝试。嗨，SK，我以前已经试过了。但我还是再试了一次，我得到了同样的例外。如果你能为我们展示页面的HTML代码，至少部分页面可以注销，我可以帮助你更好。注销这是我能分享的最大限度。我不允许分享更多。
