BeautifulSoup does not parse xml with other encoding than utf-8

Question

I can read all xmls files that starts with <?xml version="1.0" encoding="utf-8"?> but I can not read the files starts with <?xml version="1.0" encoding="ISO-8859-1"?>.

Specifically, I have two files:

xml_iso.xml:

<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
    <to>Tove</to>
    <from>Jani</from>
    <heading>Reminder</heading>
</note>

xml-utf.xml:

<?xml version="1.0" encoding="utf-8"?>
<note>
    <to>Tove</to>
    <from>Jani</from>
    <heading>Reminder</heading>
</note>

With the following code I can find the note for the file with utf-8 but I can not find it in the file with the other encoding. How can I solve that?

Example code:

import unittest

from bs4 import BeautifulSoup as Soup

class TestEncoding(unittest.TestCase):
    def test_iso(self):
        with open('tests/xml-iso.xml', 'r') as f_in:
            xml_soup = Soup(f_in.read(), 'xml')
        print('xml-iso:\n{}'.format(xml_soup))
        note = xml_soup.find('note')
        self.assertIsNotNone(note)

    def test_utf8(self):
        with open('tests/xml-utf.xml', 'r') as f_in:
            xml_soup = Soup(f_in.read(), 'xml')
        print('xml-utf8:\n{}'.format(xml_soup))
        note = xml_soup.find('note')
        self.assertIsNotNone(note)

if __name__ == '__main__':
    unittest.main()

Versions:

• Python 3.5.2

• beautifulsoup4==4.6.0

Answer 1

Coincidentally I stumbled upon another workaround. Read the file in binary mode ('rb'):

with open('tests/xml-iso.xml', 'rb') as f_in:
    xml_soup = Soup(f_in.read(), 'xml')

Answer 2

I have the exact same problem. My workaround is to not read the xml declaration:

with open('tests/xml-iso.xml', 'r', encoding='iso-8859-1') as f_in:
    f_in.readline()  # skipping header and letting soup create its own header
    xml_soup = Soup(f_in.read(), 'xml', from_encoding='ISO-8859-1')
