There is a website where I need to obtain the owners of this item from an online-game item and from research, I need to do some 'web scraping' to get this data. But, the information is in a Javascript document/code, not an easily parseable HTML document like bs4 shows I can easily extract information from. So, I need to get a variable in this javascript document (contains a list of owners of the item I'm looking at) and make it into a usable list/json/string I can implement in my program. Is there a way I can do this? if so, how can I?
I've attached an image of the variable I need when viewing the page source of the site I'm on.
My current code:
from bs4 import BeautifulSoup
html = requests.get('https://www.rolimons.com/item/1029025').content #the item webpage
soup = BeautifulSoup(html, "lxml")
datas = soup.find_all("script")
print(data) #prints the sections of the website content that have ja

import requests
import json
import re
r = requests.get('...')
m = re.search(r'var history_data\s =\s (.*)', r.text)
print(json.loads(m.group(1)))
CodePudding user response：
To scrape javascript variable, can't use only BeautifulSoup. Regular expression (re) is required.
Use ast.literal_eval to convert string representation of dict to a dict.
from bs4 import BeautifulSoup
import requests
import re
import ast
html = requests.get('https://www.rolimons.com/item/1029025').content #the item webpage
soup = BeautifulSoup(html, "lxml")
ownership_data = re.search(r'ownership_data\s =\s .*;', soup.text).group(0)
ownership_data_dict = ast.literal_eval(ownership_data.split('=')[1].strip().replace(';', ''))
print(ownership_data_dict)
Output:
