Selenium xpath语法不正确

我想用Selenium在Java中创建ajax等待方法来获取配置定义的许多结果。Selenium xpath语法不正确

这里是我的方法：

/** 
    * Wait for WAIT seconds for AJAX data to be loaded. 
    * @throws Exception - if thread is interrupted 
    */ 
    public List<WebElement> waitAjaxLoad(By by) throws Exception{ 
     int ajaxResultsWait = Integer.parseInt(P.getProperty("ajax.results.wait")); 
     List<WebElement> resultsLoaded = null; 

     do{ 
      resultsLoaded = driver.findElements(by); 
     }while(resultsLoaded.size() < ajaxResultsWait); 
     return resultsLoaded; 
    }

这里是我的电话：

List<WebElement> videoElements = waitAjaxLoad(By.xpath("//div[@id='pageTv']/div[@id='pageTvScroller')]/div[@class='boxInner']/ul/li"));

我得到这个异常：

org.openqa.selenium.InvalidSelectorException: The given selector //div[@id='pageTv']/div[@id='pageTvScroller')]/div[@class='boxInner']/ul/li is either invalid or does not result in a WebElement. The following error occurred: InvalidSelectorError: Unable to locate an element with the xpath expression //div[@id='pageTv']/div[@id='pageTvScroller')]/div[@class='boxInner']/ul/li because of the following error: [Exception... "The expression is not a legal expression." code: "12" nsresult: "0x805b0033 (SyntaxError)" location: ""] Command duration or timeout: 20 milliseconds

我应该wory约XPath表达式不是snytax正确，否则Selenium无法找到该WebElement？此异常暧昧我....

它是一种简单的打字错误，不必要的轮支架在div[@id='pageTvScroller')]增加，因此更换

//div[@id='pageTv']/div[@id='pageTvScroller')]/div[@class='boxInner']/ul/li

与

//div[@id='pageTv']/div[@id='pageTvScroller']/div[@class='boxInner']/ul/li
