硒与VB.NET - 找不到元素

Question

我是新来的硒，我偶然发现一个错误。

我试图从网站下载一个特定的文件（见代码），当我到达网站的最后一部分下载链接变得可用时，我无法选择'下载完整证券列表”。我已经尝试过使用XPath CSS选择器等等。

你们中的任何一位技术精通的人能否提出一个修正/建议？

任何帮助将是伟大的！

谢谢 吉汗

    System.Threading.Thread.Sleep(1000)

End Sub 

Answer 1

这是通过搜索链接文本，而不是下载链接的XPATH解决。之前和具体如下：

'download my holdings 
Dim myData As IWebElement = driver.FindElement(By.XPath("//*[@id='ctl02_ctl15_ctl00_container']div[2]/div[3]/div/div[4]/div[2]/div/a/div[2]/span")) 
System.Threading.Thread.Sleep(1000) 
myData.Click() 

现在

：

'download my holdings 
    Dim myData As IWebElement = driver.FindElement(By.LinkText("Download Full Securities List")) 
    System.Threading.Thread.Sleep(1000) 
    myData.Click()
