Ways to fix

Error code:

from youtube_dl.compat import compat_etree_fromstring
from youtube_dl.utils import xpath_text

testxml = '''<root>
            <div>
            </div>
        </root>'''

doc = compat_etree_fromstring(testxml)

xpath_text(doc, 'div/p',fatal=True)

Explanation:

The error is raised when using xpath_text. It extracts text from a given XPath based on given tags. In the above example, we will get an error because we don't have a <p> tag to parse.

To avoid an error,

1) change the fatal parameter to True

2) pass exact tags to parse

Fix code:

from youtube_dl.compat import compat_etree_fromstring
from youtube_dl.utils import xpath_text

testxml = '''<root>
            <div>
                <p>Foo</p>
            </div>
        </root>'''
doc = compat_etree_fromstring(testxml)

xpath_text(doc, 'div/p',fatal=True)
