尝试从按钮获取纬度和经度数据

Question

我试图从这个结果页面的“Show Map”按钮中刮出纬度和经度数据:https://www.psychologytoday.com/us/therapists/60148/374863?sid=5d01e84909804&ref=2&tr=resultsName:https://www.psychologytoday.com/us/therapists/60148/374863?sid=5d01e84909804&ref=2&tr=resultsName

这是我目前尝试的方法=

button = soup.find('button', {"data-event-label":'Address_MapButton'})
print(button['data-map-lat'])

完整代码：从bs4导入请求从bs4导入BeautifulSoup.元素导入标记

zipcode = int(input("Zipcode: "))
url = 'https://www.psychologytoday.com/us/therapists/{0}'.format(zipcode)
headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36'}

page = requests.get(url, headers=headers)
soup = BeautifulSoup(page.text, 'html.parser')
result = soup.find(class_='results-column')

addressArray = []

for tag in result:
    if isinstance(tag,Tag):
        _class = tag.get("class")

        if _class is None or _class is not None and "row" not in _class:
            continue

        link = (tag.find(class_='result-actions')).find('a',href=True)

        _href = link['href']

        address_link = requests.get(_href, headers=headers)
        soup1 = BeautifulSoup(address_link.text, 'html.parser')

        address = (soup1.find(class_='address')).find(class_="location-address-phone")
        button = soup.find('button', {"data-event-label":'Address_MapButton'})
        print(button['data-map-lat'])

print(addressArray)

我得到的回报是零。我想看看纬度坐标。

您希望提取适当的属性。我使用类btn-location上的第一个匹配来获取包含属性的元素。

import requests
from bs4 import BeautifulSoup as bs

r = requests.get('https://www.psychologytoday.com/us/therapists/60148/374863?sid=5d01e84909804&ref=2&tr=ResultsName', headers = {'User-Agent': 'Mozilla/5.0'})
soup = bs(r.content, 'lxml')
elem = soup.select_one('.btn-location[data-map-lat]')
lat = elem['data-map-lat']
lon = elem['data-map-lon']
print(lat, lon) 

OP的版本：

soup2 = bs(address_link.content, 'lxml') 
elem = soup2.select_one('.btn-location[data-map-lat]') 
lat = elem['data-map-lat'] 
lon = elem['data-map-lon'] 
latArray.append(lat)
