如何在python中将xml文件转换为csv,python,Python,我是python的初学者。即使有很多xml到csv的例子，但当我做一些事情时，我仍然不明白这个关键点。xml文件如下所示： <?xml version="1.0" encoding="ISO-8859-1"?> <spec:BACKUPCFG xmlns:spec="http://" > <spec:fileHeader fileFormatVersion="1.2.0" nenrmversion="BTS3900DATAV100R012C10SPC100"

我想从xml中获取csv数据，就像下表一样，但我做不到

使用lxml：

from lxml import etree

xmlparser = etree.XMLParser()

with open('xml-csv/CFGDATA.XML') as xmlfile:
    tree = etree.parse(xmlfile, xmlparser)
cells = tree.xpath("//Cell")  

for cell in cells:
    LocalCellId = cell.find('attributes/LocalCellId').text
    CellName = cell.find('attributes/CellName').text
    FreqBand = cell.find('attributes/FreqBand').text
    DlEarfcn = cell.find('attributes/DlEarfcn').text
    CellId = cell.find('attributes/CellId').text
    PhyCellId = cell.find('attributes/PhyCellId').text
    print(LocalCellId,CellName,FreqBand,DlEarfcn,CellId,PhyCellId,sep=',')

输出：

60,NJ0003P_9NB01_S01,8,3750,60,128
61,NJ0003P_9NB01_S02,8,3750,61,192
62,CBR0003P_9NB01_S03,8,3750,62,194

您是否得到错误，或者您的输出与您预期的不同？请描述一下你现在得到了什么。发生了什么？你有输出吗？对吗？如果没有，这是怎么回事？抱歉，运行此代码时遇到如下错误：--------------------------------------------------------------------------------------PermissionError回溯（最近一次调用）在（）1 root=tree.getroot（）2-->3中打开（'config.csv'，'w'，newline=''）as r:4 writer=csv.writer（r）5 writer.writerow（['LocalCellId'，'CellName'，'frequeband'，'DlEarfcn'，'CellId'，'PhyCellId']）权限错误：[Errno 13]权限被拒绝：'config.csv'：-）如果答案有效，请接受它（在投票分数下打勾）。非常感谢。
