Python的XML競技選手

Question

我要打印的姓，名，PROTEAM，並對該XML http://api.cbssports.com/fantasy/players/list?version=3.0&SPORT=basketball

每個玩家的標題這是到目前爲止我的代碼，但它不工作

from urllib2 import Request, urlopen, URLError 
import xml.etree.ElementTree as ET 

request = Request('http://api.cbssports.com/fantasy/players/list?version=3.0&SPORT=basketball') 

try: 
    response = urlopen(request) 
    tree = ET.parse(response) 
    root = tree.getroot() 
    for player in root.findall('.//players'): 
     firstname = player.find('firstname').text 
     lastname = player.find('lastname').text 
     print firstname, lastname 
except URLError, e: 
    print 'error:', e 

我相信錯誤是在for循環語句，因爲名字是不是玩家直接子，其父是玩家ID

Answer 1

前面加上雙斜線的背景下，當前元素內的任意位置進行搜索。而你需要遍歷player元素，而不是players：

for player in root.findall('.//players/player'): 
    firstname = player.findtext('.//firstname') 
    lastname = player.findtext('.//lastname')
