無法從嵌套的XML

Question

import xml.etree.ElementTree as ET 

tree = ET.parse("D:\Parsed_CCD.xml") 
doc = tree.getroot() 


codeList=[] 
codeSystemList=[] 
codeSystemName=[] 
displayName=[] 
code=[] 
codeS=[] 
codeN=[] 
display=[] 
status=[] 
stime=[] 
etime=[] 


for elem1 in doc.findall('.//medicationsInfo/entryInfo/productCode/code'): 
    codeList.append(elem1.text) 

for elem2 in doc.findall('.//medicationsInfo/entryInfo/productCode/codeSystem'): 
    codeSystemList.append(elem2.text) 


for elem3 in doc.findall('.//medicationsInfo/entryInfo/productCode/codeSystemName'): 
    codeSystemName.append(elem3.text) 

for elem4 in doc.findall('.//medicationsInfo/entryInfo/productCode/displayName'): 
    displayName.append(elem4.text) 

for elem5 in doc.findall('.//medicationsInfo/entryInfo/productCode/translation/code'): 
    code.append(elem5.text) 

for elem6 in doc.findall('.//medicationsInfo/entryInfo/productCode/translation/codeSystem'): 
    codeS.append(elem6.text)  

for elem7 in doc.findall('.//medicationsInfo/entryInfo/productCode/translation/codeSystemName'): 
    codeN.append(elem7.text) 

for elem9 in doc.findall('.//medicationsInfo/entryInfo/productCode/translation/displayName'): 
    display.append(elem9.text) 

for elem8 in doc.findall('.//medicationsInfo/entryInfo/statusCode'): 
    status.append(elem8.text) 

for elem10 in doc.findall('.//medicationsInfo/entryInfo/startTime'): 
    stime.append(elem10.text) 

for elem11 in doc.findall('.//medicationsInfo/entryInfo/endTime'): 
    etime.append(elem11.text) 


for i in range(len(codeList)): 
    print (codeList[i],codeSystemList[i],codeSystemName[i],displayName[i],code[i],codeS[i],codeN[i],status[i],etime[i]) 

獲取所有數據，我需要打印的所有值列明智的，但問題是我在打印數據列明智的，但我不能，因爲我有一個獲取所有數據嵌套的xml文件，它具有不同數量的值。 for循環僅達到最小值，其餘數據不顯示。是否有可能像i和j一樣使用不同的循環，並將它們追加並顯示出來？

看一看的itertools.izip_longest功能這一點，將在空格中插入無，應該解決您的問題

rows=list(itertools.izip_longest(codeList,codeSystemList,codeSystemName,displayName,code,codeS,codeN,status,etime)) for row in rows: print(row)
