reviewCount我想使用 beautiful soup 從腳本標(biāo)簽中提取。嘗試了不同的方法但沒有成功。<script type="application/json" data-initial-state="review-filter">{"languages":[{"isoCode":"all","displayName":"Toutes les langues","reviewCount":"573"},{"isoCode":"fr","displayName":"fran?ais","reviewCount":"567"},{"isoCode":"en","displayName":"English","reviewCount":"6"}],"selectedLanguages":["all"],"selectedStars":null,"selectedLocationId":null}</script>

這應(yīng)該可行，我絕對(duì)確定有一種更優(yōu)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":"fran?ais","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']))

輸出：


Toutes les langues: 573

fran?ais: 567

English: 6

導(dǎo)入 json 并加載數(shù)據(jù)json，然后 iterarte 獲取所有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":"fran?ais","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'])

輸出：


573

567

6
