如何将解析后的XML转换为python中的pandas dataframe或CSV？

import xml.etree.ElementTree as ET
import pandas as pd

tree = ET.parse('file.xml')  # 替换为你的XML文件路径
root = tree.getroot()

data = []
for child in root:
    row = {}
    for sub_child in child:
        row[sub_child.tag] = sub_child.text
    data.append(row)

df = pd.DataFrame(data)

df.to_csv('output.csv', index=False)  # 替换为你想要保存的CSV文件路径
