It seems to be a website with javascript, but I don't know how to get it.

Answer 1

The website does 3 API calls in order to get the data.
The code below does the same and get the data.

(In the browser do F12 -> Network -> XHR and see the API calls)

import requests

payload1 = {'language':'ca','documentId':680124}
r1 = requests.post('https://portaldogc.gencat.cat/eadop-rest/api/pjc/getListTraceabilityStandard',data = payload1)
if r1.status_code == 200:
  print(r1.json())

print('------------------')
payload2 = {'documentId':680124,'orderBy':'DESC','language':'ca','traceability':'02'}
r2 = requests.post('https://portaldogc.gencat.cat/eadop-rest/api/pjc/getListValidityByDocument',data = payload2)
if r2.status_code == 200:
  print(r2.json())

print('------------------')

payload3 = {'documentId': 680124,'traceabilityStandard': '02','language': 'ca'}
r3 = requests.post('https://portaldogc.gencat.cat/eadop-rest/api/pjc/documentPJC',data=payload3)
if r3.status_code == 200:
  print(r3.json())
