我不能解析这个似乎没有任何引用类的XML。美丽的汤解析问题

我的代码片段：

sock = urllib2.urlopen(l) 
link = sock.read() 

soup = BeautifulSoup(link,"xml") 

FirstNameHome=soup.find('home_probable_pitcher','first_name')

我想找到的名字同时为家庭和客队：

（即使世界只有两种情况，所以不知道我是否应该使用findAll）

下面是使用源soup.prettify

请加（在你的例子'l'对象）URL的例子 –

http://gd2.mlb.com /components/game/mlb/year_2017/month_06/day_03/gid_2017_06_03_arimlb_miamlb_1/linescore.xml –

请注意，URL输出将在2017年3月6日后发生变化 –

如果我们写

# for Python 3 
# import urllib.request 

import urllib2 

from bs4 import BeautifulSoup 

l = 'http://gd2.mlb.com/components/game/mlb/year_2017/month_06/day_03/gid_2017_06_03_arimlb_miamlb_1/linescore.xml' 

sock = urllib2.urlopen(l) 
# for Python 3 
# sock = urllib.request.urlopen(l) 
link = sock.read() 

soup = BeautifulSoup(link, "xml") 

FirstNameHome = soup.find('home_probable_pitcher').attrs['first_name'] 
print(FirstNameHome)

它给

Edinson

也

print(soup.prettify(encoding='utf-8'))

给

我可以重现你的错误，只有当我通过link对象（或str(soup)）到prettify方法

soup.prettify(link)

很好，这是不是你所需要的，因为prettify参数可以是encoding（'utf-8'例如）和formatter（默认为'minimal'），而不是原始内容，所以只写

pretty = soup.prettify()

，它会给

>>> type(pretty) 
<type 'unicode'>

或指定编码

>>> pretty = soup.prettify(encoding='utf-8')

，它会给

>>> type(pretty) 
<type 'str'>

谢谢..我没有太在意查找错误，因为我只需要知道如何解析这个名字。看起来像FirstNameHome = soup.find（'home_probable_pitcher'）。attrs ['first_name'] 这样做。我马上会再检查一次。 –

@DannyW：让我知道它是否可以改进 –
