testXML

import xml.etree.ElementTree as ET
tree = ET.parse("xml_test.xml")
root = tree.getroot()
print(root)
print(root.tag)
# 遍历xml文档
for child in root:
    print(child.tag, child.attrib)
    for i in child:
        print(i.tag, i.text,i.attrib)

遍历xml文档

import xml.etree.ElementTree as ET
tree = ET.parse("xml_test.xml")
root = tree.getroot()
for node in root.iter('year'):
    print(node.tag, node.text)

只遍历year 节点
