如何使用美丽的汤从脚本标签中提取json? [英] How to extract json from script tag using beautiful soup?

问题描述

我想使用美丽的汤从脚本标签中提取 reviewCount.尝试了不同的方法，但没有成功.

I want to extract the reviewCount from the script tag using beautiful soup. Tried different approach but didn't succeed.

<script type="application/json" data-initial-state="review-filter">
{"languages":[{"isoCode":"all","displayName":"Toutes les langues","reviewCount":"573"},{"isoCode":"fr","displayName":"français","reviewCount":"567"},{"isoCode":"en","displayName":"English","reviewCount":"6"}],"selectedLanguages":["all"],"selectedStars":null,"selectedLocationId":null}
</script>

推荐答案

这应该可行，我绝对肯定有更优雅的方法:

This should work, I am absolutely sure there is a more elegant approach:

import json
from bs4 import BeautifulSoup

html = '''
<script type="application/json" data-initial-state="review-filter">
{"languages":[{"isoCode":"all","displayName":"Toutes les langues","reviewCount":"573"},{"isoCode":"fr","displayName":"français","reviewCount":"567"},{"isoCode":"en","displayName":"English","reviewCount":"6"}],"selectedLanguages":["all"],"selectedStars":null,"selectedLocationId":null}
</script>
'''

soup = BeautifulSoup(html, 'html.parser')
res = soup.find('script')
json_object = json.loads(res.contents[0])

for language in json_object['languages']:
    print('{}: {}'.format(language['displayName'], language['reviewCount']))

输出:

Toutes les langues: 573
français: 567
English: 6
