Question

我想使用漂亮的汤从脚本标签中提取reviewCount。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 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

Answer 2

导入json并将数据加载到json中，然后依次获取所有reviewCount。

import json
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")
item=soup.select_one('script[data-initial-state="review-filter"]').text
jsondata=json.loads(item)
for item in jsondata['languages']:
    print(item['reviewCount'])

输出：

573
567
6

Answer 3

import re

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>'''


match = [item.group(1) for item in re.finditer('reviewCount":"(.+?)"', html)]

print(match)

输出：

['573', '567', '6']
