我正在尝试使用xml.etree.ElementTree解析Wikipedia XML文件的编辑历史记录，并创建一个包含以下信息的列的数据框：（修订/ id，修订/时间戳，修订/贡献者/用户名，修订/ contributor / id，修订/注释，修订/文本）。
我是Python的新手，所以我一直在尝试在线查找资源，但没有找到与我需要的资源匹配的东西。我正在尝试编辑在这里找到的功能... https://robertopreste.com/blog/parse-xml-into-dataframe ...以完成工作。但是，该功能似乎不足以提取嵌套在多个级别中的数据。
import pandas as pd
import xml.etree.ElementTree as et
def parse_XML(xml_file, df_cols):
xtree = et.parse(xml_file)
xroot = xtree.getroot()
out_df = pd.DataFrame(columns = df_cols)
for node in xroot:
res = []
res.append(node.find(df_cols[0]))
for el in df_cols[1:]:
if node is not None and node.find(el) is not None:
res.append(node.find(el).text)
else:
res.append(None)
out_df = out_df.append(pd.Series(res, index = df_cols), ignore_index = True)
return out_df
parse_XML(wiki_url,["timestamp","contributor","comment","text"])
这是xml的样子：

==Plot==
[[Image:brad_pitt6.jpg|150px|right|Brad Pitt as Tyler Durden with Edward Norton as the Narrator]]
Though the plot is mostly similar to the novel, some significant changes have been made. The originally nameless narrator is now named in publicity for the movie as "Jack" (although his real name, like in the novel, is never mentioned in the dialog). Tyler Durden is now a soap salesman instead of a beach artist. The narrator is now not entirely aware of what Tyler is doing with Project Mayhem and thus becomes increasingly uncomfortable with the increasing destructiveness of their activities, rather than being partially in control of it as in the book. Tyler is now the result of the narrator's repressed anger towards his modern life instead of his feelings for Marla.
