使用python元素树从xml在Excel工作表中创建子表格

Question

<?xml version="1.0" encoding="UTF-8"?> 

-<Metrics>  

    -<File name="N:/Users/Source/Callbacks.c">  

    -<Entity name="N:/Users/Source/CAN_Callbacks.c" type="file"> 

     <Metric name="STTDE" value="2.205"/> 

     <Metric name="STM28" value="27"/> 

     <Metric name="STTDO" value="1.999"/> 

    </Entity> 

    -<Entity name="ApplNwmBusoff" type="function"> 

     <Metric name="STM07" value="1"/> 

     <Metric name="STUNV" value="1"/> 

     <Metric name="STSUB" value="1"/> 

    </Entity> 

    </File> 

</Metrics> 

这是xml代码。我想创建一个Excel工作表的子表如下：

这是我的代码：

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

dir = r"C:\Users\HIL Tester\projt\prqa\reports\projt_MDR_13062017_112431.xml" 
file_name = [] 
metric_name = [] 
metric_value = [] 
table_end_indices = [] 
metric_name_lists = [] 
metric_value_lists = [] 
main_list = [] 





tree = ET.parse(dir) 
root = tree.getroot() 

for child in root[0].iter('Entity'): 
    file_name.append(child.get('name')) 


for table_ind in range(len(root[0])): 
    for c in root[0][table_ind].iter('Metric'): 
     metric_name.append(c.get('name'))#all the headers are appended to metric name list 
     metric_value.append(c.get('value'))#all the values are appended to metric value list 


data_frame1 = pd.DataFrame(file_name) 
data_frame2 = pd.DataFrame(metric_name) 
data_frame3 = pd.DataFrame(metric_value) 
frames = [data_frame1, data_frame2, data_frame3] 
result = pd.concat(frames) 
result=result.transpose() 
writer = pd.ExcelWriter(r'N:\Users\xml\report.xlsx') 
result.to_excel(writer, 'xml_report') 
writer.save() 

但这个代码生成此表format.I要创建在上述表格式。有人能帮助我吗？使用openpyxl

解，例如：

from openpyxl import Workbook 

wb = Workbook() 
ws = wb.worksheets[0] 
ws.title = 'xml_report' 

tree = ET.parse(xml) 
root = tree.getroot() 

for entity in root[0].iter('Entity'): 
    subtable_header = [] 
    subtable_header.append(entity.get('name')) 
    subtable_values = [''] 
    for metric in entity.iter('Metric'): 
     subtable_header.append(metric.get('name')) 
     subtable_values.append(metric.get('value')) 

    ws.append(subtable_header) 
    ws.append(subtable_values) 

wb.save('N:\Users\xml\report.xlsx') 

输出：

Python测试：3.4.2 - openpyxl：2.4.1 - LibreOffice：4.3.3.2
