硒與VB.NET - 找不到元素

Question

我是新來的硒，我偶然發現一個錯誤。

我試圖從網站下載一個特定的文件（見代碼），當我到達網站的最後一部分下載鏈接變得可用時，我無法選擇'下載完整證券列表」。我已經嘗試過使用XPath CSS選擇器等等。

你們中的任何一位技術精通的人能否提出一個修正/建議？

任何幫助將是偉大的！

謝謝 吉汗

    'change to "ETF Information tab" to gather required data 
    Dim myFundHoldings As IWebElement = driver.FindElement(By.XPath("//*[@id='ctl02_ctl15_ctl00_ctl01_126']/span")) 
    System.Threading.Thread.Sleep(1000) 
    myFundHoldings.Click() 


    '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() 
End Sub 

Answer 1

這是通過搜索鏈接文本，而不是下載鏈接的XPATH解決。之前和具體如下：

'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() 

現在

：

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