1、movies.xml
<collection shelf="New Arrivals"> <movie title="Enemy Behind"> <type>War, Thriller</type> <format>DVD</format> <year>2003</year> <rating>PG</rating> <stars>10</stars> <description>Talk about a US-Japan war</description> </movie> <movie title="Transformers"> <type>Anime, Science Fiction</type> <format>DVD</format> <year>1989</year> <rating>R</rating> <stars>8</stars> <description>A schientific fiction</description> </movie> </collection>
2、python代码
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)
3、一些方法
Element.findAll():查找当前element的孩子的属于某个tag的element;
Element.find():查找属于某个tag的第一个element;
Element.text:访问Element的文本内容;
Element.get():访问Element的属性; (当属性>1的时候很有用)
Element.iter():迭代遍历子节点。
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)
