Span类XPath中的C＃Selenium按钮（Amazon.com）

Question

我正在尝试在XPATH中创建正确的C#语法，以点击亚马逊商业网站上的下载按钮。我尝试的一切都无法找到按钮。以下是我尝试过的一些事情：

driver.FindElement(By.XPath("//button[@type='submit']")).Submit();

driver.FindElement(By.XPath("//span[contains(@class,'a-button-inner')][contains(text(),'downloadCSV_button-announce')]")).Submit(); 

driver.FindElement(By.XPath("//span[contains(@class,'a-button-inner')][contains(text(),'Download CSV')]")).Submit();

以下是亚马逊网页的源代码。谁能帮我设计合适的XPATH查询来点击这个下载按钮？谢谢。

    <div class="a-column a-span12">
        <span class="a-declarative" data-action="aba:download-csv" data-aba:download-csv="{}">
            <span id="downloadCSV_button" class="a-button aok-float-right"><span class="a-button-inner"><input class="a-button-input" type="submit" aria-labelledby="downloadCSV_button-announce"><span id="downloadCSV_button-announce" class="a-button-text" aria-hidden="true">Download CSV</span></span></span>
        </span>

您应该尝试使用WebElement#click()来执行点击元素，如下所示： -

driver.FindElement(By.CssSelector("input.a-button-input[aria-labelledby = 'downloadCSV_button-announce']")).Click();

或者如果span元素可点击，请尝试： -

driver.FindElement(By.Id("downloadCSV_button-announce")).Click();

或者

driver.FindElement(By.Id("downloadCSV_button")).Click();
