创建带缩进的XML

 1 from xml.etree import ElementTree as ET
 2 from xml.dom import minidom
 3 
 4 root = ET.Element('root',{'age':'18'})
 5 
 6 son=ET.SubElement(root,'root',{'age':'18'})
 7 ET.SubElement(son,'haha',{'bb':'fhfhf'})
 8 
 9 # tree = ET.ElementTree(root)
10 # tree.write('aha.xml')
11 
12 def mywrite(root,file_path):
13     rough_str = ET.tostring(root,'utf-8')
14     reparsed = minidom.parseString(rough_str)
15     new_str = reparsed.toprettyxml(indent='\t')
16     f = open(file_path,'w',encoding='utf-8')
17     f.write(new_str)
18     f.close()
19 
20 mywrite(root,'nnnn.xml')

结果

<?xml version="1.0" ?>
<root age="18">
   <root age="18">
      <haha bb="fhfhf"/>
   </root>
</root>
