从 aria-label selenium webdriver (python) 中提取文本

Extract text from an aria-label selenium webdriver (python)

现在我正在开发一个程序,它接受用户输入的问题和答案,将它们分成单独的 q 和 a 列表,然后根据问题或答案自动回答问题。由于使用 'bot' 的地方在线,我使用的是 Selenium 网络驱动程序,这在尝试读取 aria-label 时导致我出现一些问题。我不知道自己做错了什么,因为我对 selenium、HTML 或 CSS 一点都不了解。我试图在不知道它是什么的情况下为每个容器找到 aria-label 值

HTML 的示例我正在尝试获取文本值:

<div class="MatchModeQuestionGridBoard-tile"><div class="MatchModeQuestionGridTile" touch-action="auto"><div class="MatchModeQuestionGridTile-content"><div aria-label="to cloak; to conceal the truth; to offer lame excuses" class="FormattedText notranslate TermText MatchModeQuestionGridTile-text lang-en" style="font-size: 14px;"><div style="display: block;">to cloak; to conceal the truth; to offer lame excuses</div></div></div></div></div>

我的代码片段:

def driver():
    driver = webdriver.Chrome()
    driver.get(link)
    startMatch = driver.find_element_by_xpath("/html/body/div[5]/div/div/div/div[2]/button").click()
   
    #find text in matches
    container = driver.find_elements_by_class_name('MatchModeQuestionGridTile-content')
    containerFile = open("QuizletTerms.txt", "w+")

    for _ in list(container):
        arialabel = driver.find_elements_by_css_selector("div[aria-label='']")
        containerFile.write("\n")
        containerFile.write(str(arialabel))
        print(arialabel)

    containerFile.close()
    print("done")
    sleep(5)

输出:


[]
[]
[]
[]
[]
[]
[]
[]
[]
[]
[]
[]

文本例如披风;隐瞒真相;提供蹩脚的借口 出现在 child <div> 中,也出现在 parent <div> 中。所以提取它你需要诱导 for visibility_of_all_elements_located() and you can use either of the following :

  • 使用 CSS_SELECTORget_attribute():

    print([my_elem.get_attribute("aria-label") for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div.MatchModeQuestionGridTile-content>div[aria-label]")))])
    
  • 使用 XPATHget_attribute():

    print([my_elem.get_attribute("aria-label") for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='MatchModeQuestionGridTile-content']/div[@aria-label]")))])
    
  • 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
