如何使用 beautiful soup 从脚本标签中提取 json？

Question

reviewCount我想使用 beautiful soup 从脚本标签中提取。尝试了不同的方法但没有成功。

<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>

Answer 1

这应该可行，我绝对确定有一种更优雅的方法：import jsonfrom bs4 import BeautifulSouphtml = '''<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']:&nbsp; &nbsp; print('{}: {}'.format(language['displayName'], language['reviewCount']))输出：Toutes les langues: 573français: 567English: 6

Answer 2

导入 json 并加载数据json，然后 iterarte 获取所有reviewCount.import jsonhtml='''<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")item=soup.select_one('script[data-initial-state="review-filter"]').textjsondata=json.loads(item)for item in jsondata['languages']:&nbsp; &nbsp; print(item['reviewCount'])输出：5735676

import rehtml = '''<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>'''match = [item.group(1) for item in re.finditer('reviewCount":"(.+?)"', html)]print(match)输出：['573', '567', '6']
