从 html 中提取 table，包括使用 Python 的图像

Question

我正在尝试从 html 下载一个 table，它不是通常的 td/tr 格式，但包含图像。

html 代码如下所示：

<div class="dynamicBottom">
<div class="dynamicLeft">
<div class="content_block details_block scroll_tabs" data-tab="TABS_DETAILS">
<div class="header_with_improve wrap">
<a href="/UpdateListing.html" onclick="ta.setEvtCookie('UpdateListing', 'entry-detail-moreinfo', null, 0, '/UpdateListingRedesign')"><div class="improve_listing_btn ui_button primary small">improve this entry</div></a>
<h3 class="tabs_header">Details</h3> </div>
<div class="details_tab">
<div class="table_section">
<div class="row">
<div class="ratingSummary wrap">
<div class="histogramCommon bubbleHistogram wrap">
<div class="colTitle">
Rating
</div>
<ul class="barChart">
<li>
<div class="ratingRow wrap">
<div class="label part ">
<span class="text">Location</span>
</div>
<div class="wrap row part ">
<span class="rate sprite-rating_s rating_s"> <img class="sprite-rating_s_fill rating_s_fill s45" src="https://static.tacdn.com/img2/x.gif" alt="45 out of fifty points">
</span>
</div>
</div>
<div class="ratingRow wrap">
<div class="label part ">
<span class="text">Service</span>
</div>
<div class="wrap row part ">
<span class="rate sprite-rating_s rating_s"> <img class="sprite-rating_s_fill rating_s_fill s45" src="https://static.tacdn.com/img2/x.gif" alt="45 out of fifty points">
</span>
</div>
</div>
</li>

我想要 table: 【位置45满分50分，服务45分（满分50分）。

以下代码仅打印 "Location" 和 "Service"，不包括评分。

for url in urls: 
    r=requests.get(url)
    time.sleep(delayTime)
    soup=BeautifulSoup(r.content, "lxml")
    data17= soup.findAll('div', {'class' :'dynamicBottom'})
    for item in (data17):
        print(item.text)

和代码

data18= soup.find(attrs={'class':  'sprite-rating_s_fill rating_s_fill s45'})
print(data18["alt"] if data18 else "No meta title given")

也无济于事，因为不清楚它代表哪个等级，因为它只打印出“50 分中的 45 分”，但不清楚是哪个类别。此外，图像标签 ('sprite-rating_s_fill rating_s_fill s45') 在其他 table 中会因评级而异。

有没有办法提取完整的table？或者告诉 Python 在某个词之后提取图像，例如"Location"?

非常感谢您的帮助！

html = '''<div class="dynamicBottom">

<div class="content_block details_block scroll_tabs" data-tab="TABS_DETAILS">
<div class="header_with_improve wrap">
<a href="/UpdateListing.html" onclick="ta.setEvtCookie('UpdateListing', 'entry-detail-moreinfo', null, 0, '/UpdateListingRedesign')"><div class="improve_listing_btn ui_button primary small">improve this entry</div></a>
<h3 class="tabs_header">Details</h3> </div>
<div class="details_tab">
<div class="table_section">
<div class="row">
<div class="ratingSummary wrap">
<div class="histogramCommon bubbleHistogram wrap">
<div class="colTitle">

</div>
<ul class="barChart">
<li>
<div class="ratingRow wrap">
<div class="label part ">

<div class="wrap row part ">
<span class="rate sprite-rating_s rating_s"> <img class="sprite-rating_s_fill rating_s_fill s45" src="https://static.tacdn.com/img2/x.gif" alt="45 out of fifty points">

</div>
</div>
</li>'''
from bs4 import BeautifulSoup
soup = BeautifulSoup(html, 'lxml')
for div in soup.find_all('div', class_="ratingRow wrap"):
    text = div.text.strip()
    alt = div.find('img').get('alt')
    print(text, alt)

输出：

Location 45 out of fifty points
Service 45 out of fifty points
