Can't get data in table form using Selenium Python

问题

Am new to scrapping using selenium python. So i could retrieve some of the data, but i want it in table form as is displayed on the web page:

Here is what i have so far:

url='https://definitivehc.maps.arcgis.com/home/item.html?id=1044bb19da8d4dbfb6a96eb1b4ebf629&view=list&showFilters=false#data'

browser = webdriver.Chrome(r"C:\task\chromedriver")
browser.get(url)
time.sleep(25)


rows_in_table = browser.find_elements_by_xpath('//table[@class="dgrid-row-table"]//tr[th or td]')
for element in rows_in_table:
    print(element.text.replace('\n', ''))

result snippet:

Hospital NameHospital TypeCityState AbrvZip CodeCounty NameState Name

I will really appreciate a help form an expert on this. Thanks.

This is an updated version to what @Andrej answered, this code will download the table and instead of printing, saves it as an excel document.

import json
import requests
import pandas as pd
from pandas.io.json import json_normalize

config_url = 'https://definitivehc.maps.arcgis.com/sharing/rest/portals/self?culture=en-us&f=json'
page_url = 'https://services7.arcgis.com/{_id}/arcgis/rest/services/Definitive_Healthcare_USA_Hospital_Beds/FeatureServer/0/query?f=json&where=1%3D1&returnGeometry=false&spatialRel=esriSpatialRelIntersects&outFields=*&orderByFields=OBJECTID%20ASC&resultOffset={offset}&resultRecordCount=50&cacheHint=true&quantizationParameters=%7B%22mode%22%3A%22edit%22%7D'

_id = requests.get(config_url).json()['id']
required=[]
offset = 0
while True:
    data = requests.get(page_url.format(_id=_id, offset=offset)).json()

    # uncommnet this to print all data:
    #pprint(json.dumps(data, indent=4))

    for i, f in enumerate(data['features'], offset+1):
        required.append(f['attributes'])


    if i % 50:
        break

    offset += 50

df=json_normalize(required)
with pd.ExcelWriter('dataFunction.xlsx', mode='A') as writer:
    df.to_excel(writer)

I tried this and uploaded the excel sheet HERE(LINK TO EXCEL SHEET)!

The data is loaded dynamically using Javascript. You can use requests module to simulate those requests:

import json
import requests

config_url = 'https://definitivehc.maps.arcgis.com/sharing/rest/portals/self?culture=en-us&f=json'
page_url = 'https://services7.arcgis.com/{_id}/arcgis/rest/services/Definitive_Healthcare_USA_Hospital_Beds/FeatureServer/0/query?f=json&where=1%3D1&returnGeometry=false&spatialRel=esriSpatialRelIntersects&outFields=*&orderByFields=OBJECTID%20ASC&resultOffset={offset}&resultRecordCount=50&cacheHint=true&quantizationParameters=%7B%22mode%22%3A%22edit%22%7D'

_id = requests.get(config_url).json()['id']

offset = 0
while True:
    data = requests.get(page_url.format(_id=_id, offset=offset)).json()

    # uncommnet this to print all data:
    # print(json.dumps(data, indent=4))

    for i, f in enumerate(data['features'], offset+1):
        print(i, f['attributes'])
        print('-' * 160)

    if i % 50:
        break

    offset += 50

Prints all 6624 records:
