[Python] How to convert an XML file to nice pandas dataframe?

Let's assume that I have an XML like this:

<author type="XXX" language="EN" gender="xx" feature="xx" web="foobar.com">
<documents count="N">
<document KEY="e95a9a6c790ecb95e46cf15bee517651" web="www.foo_bar_exmaple.com"><![CDATA[A large text with lots of strings and punctuations symbols [...]
]]>
</document>
<document KEY="bc360cfbafc39970587547215162f0db" web="www.foo_bar_exmaple.com"><![CDATA[A large text with lots of strings and punctuations symbols [...]
]]>
</document>
<document KEY="19e71144c50a8b9160b3f0955e906fce" web="www.foo_bar_exmaple.com"><![CDATA[A large text with lots of strings and punctuations symbols [...]
]]>
</document>
<document KEY="21d4af9021a174f61b884606c74d9e42" web="www.foo_bar_exmaple.com"><![CDATA[A large text with lots of strings and punctuations symbols [...]
]]>
</document>
</documents>
</author>


I would like to read this XML file and convert it to a pandas DataFrame:

key type language feature web data
e95324a9a6c790ecb95e46cf15bE232ee517651 XXX EN xx www.foo_bar_exmaple.com A large text with lots of strings and punctuations symbols [...]
bc360cfbafc39970587547215162f0db XXX EN xx www.foo_bar_exmaple.com A large text with lots of strings and punctuations symbols [...]
19e71144c50a8b9160b3cvdf2324f0955e906fce XXX EN xx www.foo_bar_exmaple.com A large text with lots of strings and punctuations symbols [...]
21d4af9021a174f61b8erf284606c74d9e42 XXX EN xx www.foo_bar_exmaple.com A large text with lots of strings and punctuations symbols [...]


This is what I already tried, but I am getting some errors and probably there is a more efficient way of doing this task:

from lxml import objectify
import pandas as pd

path = 'file_path'
xml = objectify.parse(open(path))
root = xml.getroot()
root.getchildren()[0].getchildren()
df = pd.DataFrame(columns=('key','type', 'language', 'feature', 'web', 'data'))

for i in range(0,len(xml)):
obj = root.getchildren().getchildren()
row = dict(zip(['key','type', 'language', 'feature', 'web', 'data'], [obj[0].text, obj[1].text]))
row_s = pd.Series(row)
row_s.name = i
df = df.append(row_s)


Could anybody provide me a better aproach for this problem?
