Question

我必须从this link解析阿德莱德乌鸦的玩家名称，因为我已经编写了这样的解析器

import requests                                                                 
from bs4 import BeautifulSoup

href_val = requests.get("http://www.afl.com.au/news/teams?round=9")
soup1 = BeautifulSoup(href_val.content)

players_info_adel = soup1.find_all("ul", {"class" : "team1 team-adel"})
for li in players_info_adel:

    player_names_adel = li.find_all("li", {"class" : "player"})
    #print player_names_adel

#print player_names_adel

for span in player_names_adel:

    if span.find(text = True):
        text = ''.join(span.find(text = True))
        text1 = text.encode('ascii')
        print text

但是每当我运行这段代码时，我总会得到一堆"\n"而不是名字。我该怎么做才能得到球员的名字？

Answer 1

您不希望循环超过每个玩家<li>元素;第一个元素是一个文本节点，其中只有一个换行符。最好使用Tag.get_text()来获取元素中的所有文本。

使用CSS选择器简化代码：

for player in soup1.select('ul.team1 li.player'):
    text = player.get_text().strip()
    print text

这包括球员号码;您可以使用以下方法分隔此号码和玩家名称：

number, name = player.span.get_text().strip(), player.span.next_sibling.strip()

代替。

演示：

>>> import requests
>>> from bs4 import BeautifulSoup
>>> href_val = requests.get("http://www.afl.com.au/news/teams?round=9")
>>> soup1 = BeautifulSoup(href_val.content)
>>> for player in soup1.select('ul.team1 li.player'):
...     text = player.get_text().strip()
...     print text
...

解析器返回＆＃34; \ n＆＃34;而不是期望的输出。
