I'm trying to download files for a specific date from a website using Selenium's xpath like below. I'm using it to find the link I want from a website form.

driver.findElement(By.xpath("//tr[td[contains(.,'10/30/2018')] and @class='Row ']//span")).click();

When I directly search the HTML in Chrome browser using xpath, it gaves me the result I want. However, if I use Selenium' xpath (web driver is Chrome's) in java program to locate the element, I got "No Such Element Exception". I have tried longer wait for web loading using

driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

But it did not work.

Could anyone tell me why?

I see that the link is located in a "iframe" tag. Is it something I should deal with first?

The web structure is basically like this

<tr>

  <tr class="Row ">

    <td>10/30/2018 9:00:00 PM<td>

    <td>

      <span>

        <input type="submit" value="Download"></input>

        <input type="hidden"></input>

      </span>

    </td>

  </tr>

  <tr class="Row ">

    <td>10/27/2018 9:00:00 PM<td>

    <td>

      <span>

        <input type="submit" value="Download"></input>

        <input type="hidden"></input>

      </span>

    </td>

  </tr> 

</tr> 

I also tried this and did not work.

driver.findElement(By.xpath("//tr[td[contains(.,'10/30/2018')] and @class='Row ']//input[@type='submit']")).click();

My question is solved. The reason I cannot find the element is that it's in a iframe tag. It mean it's another website inside the current website. To handle that, I need to use switchTo function to go to that website first, then I can work on it.

driver.switchTo().frame(driver.findElements(By.tagName("iframe")).get(0));
