Issue Description

At one point, importing thml table data acquired from the same from the same source, Pandas suddenly rejected file, dropping down with error: /usr/lib64/python3.9/site-packages/bs4/init.py:435: MarkupResemblesLocatorWarning: The input looks more like a filename than markup. You may want to open this file and pass the filehandle into Beautiful Soup. warnings.warn( Traceback (most recent call last): File "/home/janis/Data/Elektreiba/NOMX-04.py", line 146, in df=pd.read_html (jauni_dati) File "/usr/lib64/python3.9/site-packages/pandas/util/_decorators.py", line 331, in wrapper return func(args, *kwargs) File "/usr/lib64/python3.9/site-packages/pandas/io/html.py", line 1205, in read_html return _parse( File "/usr/lib64/python3.9/site-packages/pandas/io/html.py", line 1006, in _parse raise retained File "/usr/lib64/python3.9/site-packages/pandas/io/html.py", line 986, in _parse tables = p.parse_tables() File "/usr/lib64/python3.9/site-packages/pandas/io/html.py", line 262, in parse_tables tables = self._parse_tables(self._build_doc(), self.match, self.attrs) File "/usr/lib64/python3.9/site-packages/pandas/io/html.py", line 618, in _parse_tables raise ValueError("No tables found") ValueError: No tables found

Two consecutive files (originally misnamed as xls,representing files before and after the problem) are attached. With the first and data before it everything worked fine (no need for additional lib), with the second html5lib was requested with the message: Traceback (most recent call last): File "/home/janis/Data/Elektreiba/NOMX-04.py", line 143, in df=pd.read_html (jauni_dati) File "/usr/lib64/python3.9/site-packages/pandas/util/_decorators.py", line 331, in wrapper return func(args, *kwargs) File "/usr/lib64/python3.9/site-packages/pandas/io/html.py", line 1205, in read_html return _parse( File "/usr/lib64/python3.9/site-packages/pandas/io/html.py", line 982, in _parse parser = _parser_dispatch(flav) File "/usr/lib64/python3.9/site-packages/pandas/io/html.py", line 931, in _parser_dispatch raise ImportError("html5lib not found, please install it") ImportError: html5lib not found, please install it

Both files look pretty similar and both open the same way in Firefox and Excel.

Expected Behavior

import of html table in both cases example.zip

I recall the bug report - suddenly everything started to work without html5lib or other interference
