beautifulsoup 4-4.5.0 : parsing error on 'link' tags

[Ronald MacEachern]

Using BeautifulSoup 4-4.6.0 in python (3.6) i'm getting unexpected behaviour when parsing 'link' tags.

#Expected Result:

python3.5 -m pip freeze
beautifulsoup4==4.5.1

>>> BeautifulSoup(x, 'html.parser')

>>> y = '''<link>www.google.com</link>'''
>>> BeautifulSoup(y, 'html.parser')
<link>www.google.com</link>
>>>

I don't have html5lib lxml installed (fairly certain)

appreciate any help on this, let me know if i've made a mistake with the above.

Thanks for the report. The behavior you're seeing is by design. In revision 446, I changed the way Beautiful Soup processes HTML empty-element tags, so that any contents are moved outside the tag. This was necessary to fix bug 1676935 and make the processing of empty-element tags consistent across parsers.
