Python: BeautifulSoup UnboundLocalError

Question

I am trying to remove the HTML tags from some documents in a .txt format. However, there seems to be an error with the bs4 as far as I understand. The error that I am getting is the following:

 Traceback (most recent call last):
  File "E:/Google Drive1/Thesis stuff/Python/database/get_missing_10ks.py", line 13, in <module>
    text = BeautifulSoup(file_read, "html.parser")
  File "C:\Users\Adrian PC\AppData\Local\Programs\Python\Python37\lib\site-packages\bs4\__init__.py", line 282, in __init__
    self._feed()
  File "C:\Users\Adrian PC\AppData\Local\Programs\Python\Python37\lib\site-packages\bs4\__init__.py", line 343, in _feed
    self.builder.feed(self.markup)
  File "C:\Users\Adrian PC\AppData\Local\Programs\Python\Python37\lib\site-packages\bs4\builder\_htmlparser.py", line 247, in feed
    parser.feed(markup)
  File "C:\Users\Adrian PC\AppData\Local\Programs\Python\Python37\lib\html\parser.py", line 111, in feed
    self.goahead(0)
  File "C:\Users\Adrian PC\AppData\Local\Programs\Python\Python37\lib\html\parser.py", line 179, in goahead
    k = self.parse_html_declaration(i)
  File "C:\Users\Adrian PC\AppData\Local\Programs\Python\Python37\lib\html\parser.py", line 264, in parse_html_declaration
    return self.parse_marked_section(i)
  File "C:\Users\Adrian PC\AppData\Local\Programs\Python\Python37\lib\_markupbase.py", line 160, in parse_marked_section
    if not match:
UnboundLocalError: local variable 'match' referenced before assignment

And the code that I am using is the following:

import os
from bs4 import BeautifulSoup

path_to_10k = "D:/10ks/list_missing_10k/"

path_to_saved_10k = "D:/10ks/list_missing_10kp/"

list_txt = os.listdir(path_to_10k)

for name in list_txt:
    file = open(path_to_10k + name, "r+", encoding="utf-8")
    file_read = file.read()
    text = BeautifulSoup(file_read, "html.parser")
    text = text.get_text("\n")
    file2 = open(path_to_saved_10k + name, "w+", encoding="utf-8")
    file2.write(str(text))
    file2.close()
    file.close()

The thing is that I have used this method on 51320 documents and it worked just fine, however, there are a few documents which it cannot do. When I open those HTML documents they seem the same to me.. If anyone could have any indication of what could be the problem and how to fix it it would be great. Thank you!

Answer 1

https://github.com/scrapy/w3lib
https://w3lib.readthedocs.io/en/latest/

pip install w3lib

and

from w3lib.html import remove_tags

And then remove_tags(data) return clear data.

Answer 2

Here is a solution which is using regular expression for removing the HTML tags.

import re

TAG_RE = re.compile(r'<[^>]+>')

f = open("C:\Temp\Data.txt", "r")
strHtml=f.read()

def remove_Htmltags(text):
    return TAG_RE.sub('', text)

strClearText=remove_Htmltags(strHtml)
print(strClearText)
