BeautifulSoup and regexp: Attribute error - regex

Question

I try to extract information with beautifulsoup4 methods by means of reg. exp.
But I get the following answer:
AttributeError: 'NoneType' object has no attribute 'group'
I do not understand what is wrong.. I am trying to:
get the Typologie name: 'herenhuizen'
get the weblink
Here is my code:
import requests
from bs4 import BeautifulSoup
import re
url = 'https://inventaris.onroerenderfgoed.be/erfgoedobjecten/4778'
page = requests.get(url)
soup = BeautifulSoup(page.text, 'html.parser')
text = soup.prettify()
##block
p = re.compile('(?s)(?<=(Typologie))(.*?)(?=(</a>))', re.VERBOSE)
block = p.search(text).group(2)
##typo_url
p = re.compile('(?s)(?<=(href=\"))(.*?)(?=(\">))', re.VERBOSE)
typo_url = p.search(block).group(2)
## typo_name
p = re.compile('\b(\w+)(\W*?)$', re.VERBOSE)
typo_name = p.search(block).group(1)
Does someone have an idea where is the mistake?

Answer 1

I would change this:
## typo_name
block_reverse = block[::-1]
p = re.compile('(\w+)', re.VERBOSE)
typo_name_reverse = p.search(block_reverse).group(1)
typo_name = typo_name_reverse[::-1]
print(typo_name)
Sometimes it's easier to just reverse the string if you are looking for stuff at the end. This just finds the name at the end of your block. There are a number of ways to find what you are looking for, and we could come up with all kinds of clever regexes, but if this works that's probably enough :)
update
However I just noticed the reason the original regex was not working is to use \b it needs to be escaped like \\b or be raw like this:
## typo_name
p = re.compile(r'\b(\w+)(\W*?)$', re.VERBOSE)
typo_name = p.search(block).group(1)
Some good followed Q and A here: Does Python re module support word boundaries (\b)?
