from xml.etree.ElementTree import ElementTree, Element, tostring

e = Element('Data')
print(e.tag)

e.set('name', 'abc')
e.text = '123'
print(tostring(e))
e.text = None

print(tostring(e))

print('-'*30)
e2 = Element('Row')

e3 = Element('Open')

e3.text = '8.8'

e2.append(e3)
print(tostring(e3))

e.append(e2)
et = ElementTree(e)
et.write('element.xml')

输出结果：

Data
b'<Data name="abc">123</Data>'
b'<Data name="abc" />'
------------------------------
b'<Open>8.8</Open>'
