javascript - 如何从属性 style="display :none; 的元素中提取文本

Question

该部分的 HTML 为:

<div class="review-small-text">
 <span class="stars-rate">
    <span property="starsRating">
     <i class="fa fa-star-yellow fa-star"></i>  
     <i class="fa fa-star-yellow fa-star"></i>  
     <i class="fa fa-star-yellow fa-star"></i> 
     <i class="fa fa-star-yellow fa-star"></i>  
     <i class="fa fa-star-yellow fa-star"></i> 
  </span> 
</span>
<span property="reviewRating" typeof="Rating" style="display:none;">
    <span property="ratingValue">5</span> 
    <span property="bestRating">5</span>
    <span property="worstRating">0</span>
</span> 
<span property="itemReviewed" typeof="Service" class="">Liposuction</span> </div>

我正在尝试使用 selenium 提取特定评论的第二个跨度 ratingValue，并且我尝试使用此 css 选择器提取该值:

'div.review-small-text>span:nth-of-type(2)>span:nth-of-type(1)'

但它给了我一个空字符串。也尝试过这个

'div.review-small-text>span:nth-child(2)>span:nth-child(1)'

所以我认为问题不在于CSS选择器。显示无在这里会产生问题。有没有可能的方法来提取该值？

到目前为止我尝试过的Python源代码是:

from selenium import webdriver
import time
url = "myurlhere"
driver = webdriver.Chrome()
driver.get(url)
time.sleep(3)

all_reviews_listings = driver.find_elements_by_xpath("//div[@id='tab_reviews']/div[@class='provider_all_Reviews']/div[@id='pnlReviews']/div")

for review in all_reviews_listings:
    review_rating = review.find_element_by_css_selector('div.review-small-text>span:nth-of-type(2)>span:nth-of-type(1)').text
    print("Review Rating: ", review_rating)

Answer 1

这是获取 ratingValue 的 css。

使用 JavaScript:

review_rating = driver.execute_script("""return document.querySelector(".review-small-text > span[property='reviewRating'] > span[property='ratingValue']").textContent""")

没有 JavaScript:您也可以这样做。

driver.find_element_by_css_selector(".review-small-text > span:nth-child(2) > span[property='ratingValue']").get_attribute("textContent")
