40 
41 for country in root.findall(‘country‘):
42     rank = int(country.find(‘rank‘).text)

45 
46 tree.write(‘test.xml‘)

50 创建xml
51 
52 import xml.etree.ElementTree as ET
53 new_xml = ET.Element("NameList")
54 name = ET.SubElement(new_xml,"name",attrib={"enrolled":"yes"})
55 age = ET.SubElement(name,"age",attrib={"checked":"no"})
56 sex = ET.SubElement(name,"sex")
57 sex.text = ‘33‘
58 name2 = ET.SubElement(new_xml,"name",attrib={"enrolled":"no"})
59 age = ET.SubElement(name2,"age")
60 age.text = ‘19‘
61 
62 et = ET.ElementTree(new_xml)
63 et.write(‘test.xml‘,encoding="utf-8",xml_declaration=True)
64 ET.dump(new_xml)
