无法使用selenium pthon从HTML页面获取多个类下的标签值

Question

我想从以下 HTML 中提取“xms”

    <div class="ki-kullaniciadi member-info" member-info-memberid="12789" member-info-forumid="2613">

            <a href="/profil/12789">
            
                <b>xms</b>
            </a>
        </div>

我已经尝试过了

def scrapecomments2(url):
  tic = time.perf_counter()
  wait = WebDriverWait(wd,20)
  wd.get(url)

  data2=[]


  for comment in wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, "div.ki-kullaniciadi.member-info b"))):
          data2.append(comment.text)


  toc = time.perf_counter()
  print(data2)
  return data2

包括许多组合，例如

for comment in wait.until(EC.presence_of_all_elements_located((By.CLASS_NAME, "ki-kullaniciadi     b"))):
          data2.append(comment.text)

for comment in wait.until(EC.presence_of_all_elements_located((By.XPATH,"//div[@class='ki-kullaniciadi']/a/b"))):
      data2.append(comment.text)

它总是回来

TimeoutException                          Traceback (most recent call last)
<ipython-input-8-e105fdffd5ff> in <cell line: 1>()

TimeoutException: Message: 

但是

for comment in wait.until(EC.presence_of_all_elements_located((By.TAG_NAME,"b"))):
          data2.append(comment.text)

有效，因此看起来页面加载不存在问题。它返回页面中带有标签 b 的每个值，但我只想要“ki-kullaniciadi member-info”类上的值。

  for comment in wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, ".ki-kullaniciadi .member-info a b")))
