python - 我需要帮助查找带有定位器的元素

问题描述

我试图从这个 xpath 中获取元素，这里是代码，其中有几个元素我把代码删掉了，以避免在这里出现一百万行。

html

<keyword-text class="_nghost-fyp-81"><div class="keyword-text _ngcontent- 
fyp-81" clickabletooltiptarget="" aria-label=""><span class="keyword 
_ngcontent-fyp-81" aria-hidden="false">new york new york las vegas</span> 
<!----></div><!----><!----></keyword-text>

路径

keyword_text = self.browser.find_elements_by_xpath("//span[starts-with(@class, 'keyword')]")

错误

解决方案

以下控制台消息...

<selenium.webdriver.remote.webelement.WebElement (session="941dc1eba2f3f61bb47aa2050889d299", element="0f74389d-13b7-42e8-ba81-429388d6647c")>

...不是任何错误。

正如您所使用find_elements*的，结果keyword_text是WebElements类型的对象列表，当您打印它们时，这些对象被打印出来。

要从这些元素中的几个打印文本，例如new york new york las vegas，您必须诱导WebDriverWait forvisibility_of_all_elements_located()并且您可以使用以下任一Locator Strategies：

  • 使用CSS_SELECTOR：

    print([my_elem.text for my_elem in WebDriverWait(driver, 10).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "keyword-text>div.keyword-text>span.keyword")))])

  • 使用XPATH：

    print([my_elem.text for my_elem in WebDriverWait(driver, 10).until(EC.visibility_of_all_elements_located((By.XPATH, "//keyword-text/div[contains(@class, 'keyword-text')]/span[contains(@class, 'keyword')]")))])

  • 注意：您必须添加以下导入：

    from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
