xpath/Css select 或下面的 HTML 标签可能是什么，如何使用 Selenium xpath select 特定的单选按钮

Question

1. 下面 HTML 标签的 xpath/Css 选择器可能是什么，我的问题是如何点击 Bike.[=21 的单选按钮=]
2. 假设下面是动态单选按钮，我们有 100 个单选按钮，这里我们无法预测单选按钮的索引号

HTML:

<table> 
    <tbody>
        <tr><td class="textAlignCenter" id="clientDocTypeSelection"><input class="marginL10" name="clientRadio" type="radio"></td><td id="clientDocTypeDescription"> Bike </td></tr>
        <tr><td class="textAlignCenter" id="clientDocTypeSelection"><input class="marginL10" name="clientRadio" type="radio"></td><td id="clientDocTypeDescription"> Car </td></tr>
    </tbody> 
</table>

Answer 1

找到包含您要查找的文本的 td：

tds = driver.find_elements_by_xpath("//td[@class='textAlignCenter']")
for td in tds:
   if td.text == 'Bike':
      radio_input = td.find_element_by_xpath(".//input[@type='radio']")

Answer 2

到 radio-button with text as Bike you can use either of the following xpath based 上的 click()：

• 使用Java和normalize-space():

  driver.findElement(By.xpath("//td[@id='clientDocTypeDescription' and normalize-space()='Bike']//preceding::td[1]/input")).click();
  

• 使用Java和contains():

  driver.findElement(By.xpath("//td[contains(., 'Bike')]//preceding::td[1]/input")).click();
  

---

理想情况下 click() 在你需要诱导的元素上 for the elementToBeClickable() and you can use either of the following :

• 使用Java和normalize-space():

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//td[@id='clientDocTypeDescription' and normalize-space()='Bike']//preceding::td[1]/input"))).click();
  

• 使用Java和contains():

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//td[contains(., 'Bike')]//preceding::td[1]/input"))).click();
