假设我有这样一个XML:
<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>
我想阅读这个XML文件并将其转换为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 [...]
这就是我已经尝试过的,但我遇到了一些错误,可能有更有效的方法来完成这个任务:
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()[i].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)
有没有人可以为我提供一个更好的解决方案?
xml_data = io.StringIO('''
替换为xml_data = io.StringIO(u'''
,因为StringIO
的参数需要是 Unicode。否则会出现 "TypeError: initial_value must be unicode or None, not str" 的错误。 - Cristian Ciupituu
