import xml.etree.ElementTree as ET
tree = ET.parse("e:/movies.xml")
#root = ET.fromstring(country_data_as_string)　　#导入字符串
root = tree.getroot() #前三句导入数据并获取根元素
print (root.tag)    #取标签名
print (root.attrib)    #取属性（字典形式）
for movie in root:
    print (‘*‘*30)
    print ("title:", movie.attrib[‘title‘])    #取属性值
    print ("type:", movie[0].text)    #取子节点的内容（元素值）

for movie in root.iter(‘movie‘):
    print (movie.attrib)

#感觉和下面效果一样，不知道iter()有何妙用
for movie in root:
    print (movie.attrib)
