python xml操作

1、创建xml

import xml.etree.ElementTree as et

root = et.Element('all')              
name = et.SubElement(root,'name')     
sex = et.SubElement(name,'sex')       
age = et.SubElement(name,'age')
sex.text ='m'
age.text = '20'
name1 = et.SubElement(root,'name')
sex1 = et.SubElement(name1,'sex')
age1 = et.SubElement(name1,'age')
sex1.text ='m'
age1.text = '20'
newxml = et.ElementTree(root)
newxml.write('new.xml',encoding="utf-8",xml_declaration=True)

2、读取xml

import xml.etree.ElementTree as et
root = et.parse('new.xml')
print(root.getroot().tag)
for child in root.getroot():
    print(child.tag)
    for c in child:
        print('==',c.text)
