Which Chrome extension are you using to get that path?

Are you always interested in the square footage?  Here is a solution
using Beautiful Soup:

$ cat square-feet.py
#!/usr/bin/env python
import bs4
import requests
import sys
url = sys.argv[1]
request = requests.get(url)
soup = bs4.BeautifulSoup(request.text)
is_sqft_mark_found, is_total_mark_found = False, False
for line in soup.get_text().splitlines():
    if line.startswith("Land Sqft"):
        is_sqft_mark_found = True
        continue
    elif is_sqft_mark_found and line.startswith("Total"):
        is_total_mark_found = True
        continue
    elif is_total_mark_found:
        print(line.strip() + " total square feet.")
        break

$ python3 square-feet.py http://jeffco.us/ats/displaygeneral.do?sch=001690
11082 total square feet.
