python - 将数据框导出到 Excel 表

Question

下面的简单代码在数据框中打印某些元素及其属性。它遍历 XML 文件，查找这些元素并将它们打印出来

代码

import xml.etree.ElementTree as ET
import pandas as pd
tree = ET.parse('1last.xml')
root = tree.getroot()

for neighbor in root.iter('Description'):
    print(neighbor.attrib, neighbor.text)
for neighbor in root.iter('SetData'):
    print(neighbor.attrib)
for neighbor in root.iter('FileX'):
    print(neighbor.attrib) 
for neighbor in root.iter('FileY'):
    print(neighbor.attrib)

输出

我想将输出导出到 Excel 表格中，但它似乎不起作用我已经尝试过了

export_excel = root.to_excel (r'C:\Users\fsdf.LAPTOP-E8A1PPIN\Desktop\test\export_dataframe.xlsx', index = None, header=True)

但我收到错误消息“AttributeError：‘xml.etree.ElementTree.Element’对象没有属性‘to_excel’

这是我的 xml 文件

这就是我希望桌子看起来的样子。

一种方法是使用库，例如openpyxl​​直接编写 Excel 文件。下面显示了如何做到这一点：

import openpyxl    
from bs4 import BeautifulSoup


with open('1last.xml') as f_input:
    soup = BeautifulSoup(f_input, 'lxml')

wb = openpyxl.Workbook()
ws = wb.active
ws.title = "Sheet1"

ws.append(["Description", "num", "text"])

for description in soup.find_all("description"):
    ws.append(["", description['num'], description.text])

ws.append(["SetData", "x", "value", "xin", "xax"])

for setdata in soup.find_all("setdata"):
    ws.append(["", setdata.get('x', ''), setdata.get('value', ''), setdata.get('xin', ''), setdata.get('xax', '')])

wb.save(filename="1last.xlsx")

这将创建一个 Excel 文件，如下所示：
