如何提取以电话开头并以 } 结尾的短语

如何使用正则表达式和 Python 提取以 phone 开头并以"}"结尾的短语

我试图从页面源中提取数据。

{"meta":{"subtitle":"Apartment for Rent in Marina Gate 1, Marina Gate","price":145000,"price_text":"145,000 AED/year","contact_options":{"list":{"phone":{"type":"phone","value":"+XXXXXXXX","link":"tel:+XXXXXXXX","is_did":true},"email":{"type":"email","value":"[e-mail]","link":"mailto:[e-mail]"}},"details":{"phone":{"type":"phone","value":"+XXXXXXXX","link":"tel:+XXXXXXXX","is_did":true},"sms":{"type":"sms","value":"+XXXXXXXX","link":"sms:+XXXXXXXX"},"email":{"type":"email","value":"[e-mail]","link":"mailto:[e-mail]"}}},"images_count":11}}'

我想用正则表达式提取所有以电话开头并以 } 结尾的短语

我试过 re.findall(r"^phone(.*(}$"，source(

这就是我想要的"电话"，"值"："+XXXXXXXX"，"链接"："tel：+XXXXXXXX"，"is_did"：true}

Answer 1

为此

使用 json 而不是正则表达式可能更好。试试这个，

import json
test_str = '{"meta":{"subtitle":"Apartment for Rent in Marina Gate 1, Marina Gate","price":145000,"price_text":"145,000 AED/year","contact_options":{"list":{"phone":{"type":"phone","value":"+XXXXXXXX","link":"tel:+XXXXXXXX","is_did":true},"email":{"type":"email","value":"[e-mail]","link":"mailto:[e-mail]"}},"details":{"phone":{"type":"phone","value":"+XXXXXXXX","link":"tel:+XXXXXXXX","is_did":true},"sms":{"type":"sms","value":"+XXXXXXXX","link":"sms:+XXXXXXXX"},"email":{"type":"email","value":"[e-mail]","link":"mailto:[e-mail]"}}},"images_count":11}}'
print test_str
json_str = json.loads(test_str)
print json_str
phone_num = json_str['meta']['contact_options']['list']['phone']
print phone_num

Answer 2

你可以试试这段代码(用re解析<script>标签(：

import requests
import json
import re
html_text = requests.get('https://www.propertyfinder.ae/en/rent/apartment-for-rent-dubai-dubai-marina-marina-gate-marina-gate-1-6951117.html').text
data = json.loads(re.findall(r'payloads*:s*(.*?)n', html_text)[0])
for d in data['data']:
    print(d['meta']['subtitle'])
    print(d['meta']['contact_options'])
    print('*' * 80)
