方式1：ET.Element()

需求:

  1. <home>
  2.     <son name="儿1">
  3.         <grandson name="儿11"></grandson>
  4.         <grandson name="儿12"></grandson>
  5.     </son>
  6.     <son name="儿2"></son>
  7. </home>
  1. from xml.etree import ElementTree as ET
  3. # 创建home 根标签
  4. root = ET.Element('home')
  6. # 创建两个son子节点
  7. son1 = ET.Element('son',{'name':'儿1'})
  8. son2 = ET.Element('son',{'name':'儿2'})
  10. # 创建grandson 孙节点
  11. grandson1 = ET.Element('grandson',{'name':'儿11'})
  12. grandson2 = ET.Element('grandson',{'name':'儿12'})
  14. # 将孙节点放入 第一个子节点
  15. son1.append(grandson1)
  16. son1.append(grandson2)
  18. # 将两个子节点 放入根标签
  19. root.append(son1)
  20. root.append(son2)
  23. # 保存文件设置
  24. tree = ET.ElementTree(root)
  25. tree.write('new3.xml',encoding = 'utf-8')

方式2：ET.makeelement()

个人认为这种方式没什么卵用，因为无非是吧刚才的Element改成了这个，剩下的一样
需求：

  1. <famliy>
  2.     <son name="儿1">
  3.         <grandson name="儿11"></grandson>
  4.         <grandson name="儿12"></grandson>
  5.     </son>
  6.     <son name="儿2"></son>
  7. </famliy>
  1. from xml.etree import ElementTree as ET
  3. # 创建根节点
  4. root = ET.Element("famliy")
  7. # 创建大儿子
  8. son1 = root.makeelement('son', {'name': '儿1'})
  9. # 创建小儿子
  10. son2 = root.makeelement('son', {"name": '儿2'})
  12. # 在大儿子中创建两个孙子
  13. grandson1 = son1.makeelement('grandson', {'name': '儿11'})
  14. grandson2 = son1.makeelement('grandson', {'name': '儿12'})
  16. son1.append(grandson1)
  17. son1.append(grandson2)
  20. # 把儿子添加到根节点中
  21. root.append(son1)
  22. root.append(son2)
  24. tree = ET.ElementTree(root)
  25. tree.write('oooo.xml',encoding='utf-8')

方式3：ET.SubElement()

需求：

  1. <famliy>
  2.     <son name="儿1">
  3.         <age name="儿11">孙子</age>
  4.     </son>
  5.     <son name="儿2"></son>
  6. </famliy>
  1. from xml.etree import ElementTree as ET
  3. # 创建根标签
  4. root = ET.Element('family')
  6. # 创建子节点 孙子节点
  7. son1 = ET.SubElement(root,'son',attrib={'name':'儿1'})
  8. grandson = ET.SubElement(son1,'age',attrib={'name':'儿11'})
  9. son2 = ET.SubElement(root,'son',attrib={'name':'儿2'})
  10. grandson.text = '孙子'
  12. # 保存文件
  13. tree = ET.ElementTree(root)
  14. tree.write('new4.xml',encoding='utf-8')
