如何将一个字典转换为XML文档，并将该XML文档保存成文本文件

import dicttoxml
import os
from xml.dom.minidom import parseString

d = [20,'names',{'name':'Bill','age':30,'salary':2000},
                {'name':'Mike','age':40,'salary':3000},
                {'name': 'John', 'age': 20, 'salary': 1000}]

bxml = dicttoxml.dicttoxml(d,custom_root='persons')
xml = bxml.decode('utf-8')
print(xml)
dom = parseString(xml) ## string 转 xml
prettyxml = dom.toprettyxml(indent='  ') ## 设置缩进
print(prettyxml)

f = open('files/persons1.xml','w',encoding='utf-8')
f.write(prettyxml)
f.close()

<?xml version="1.0" ?>
<persons>
  <item type="int">20</item>
  <item type="str">names</item>
  <item type="dict">
    <name type="str">Bill</name>
    <age type="int">30</age>
    <salary type="int">2000</salary>
  </item>
  <item type="dict">
    <name type="str">Mike</name>
    <age type="int">40</age>
    <salary type="int">3000</salary>
  </item>
  <item type="dict">
    <name type="str">John</name>
    <age type="int">20</age>
    <salary type="int">1000</salary>
  </item>
</persons>

需要2个第三方模块（需要安装）

• dicttoxml用于将字典转换为XML文档
• xmltodict用于将XML文档转换为字典
