我使用BeautifulSoup来解析这个网站：
http://www.livescore.com/soccer/champions-league/
我希望获得带数字的行的链接：
FT Zenit St. Petersburg 3 - 0 Standard Liege"
3 - 0是一个链接链接;我想要做的是找到每个带数字的链接（所以不是像
那样的结果 15:45 APOEL Nicosia ? - ? Paris Saint Germain
），所以我可以加载这些链接并解析分钟数据（<td class="min">）
您好!!!需要编辑。现在我能够获得链接。像这样：
import urllib2, re, bs4
sitioweb = urllib2.urlopen('http://www.livescore.com/soccer/champions-league/').read()
soup = bs4.BeautifulSoup(sitioweb)
href_tags = soup.find_all('a', {'class':"scorelink"})
links = []
for x in xrange(1, len(href_tags)):
insert = href_tags[x].get("href");links.append(insert)
print links
现在我的问题如下：我想把所有这些写进一个DB（比如sqlite），其中包含一个目标的分钟数（这个信息我可以从我得到的链接中得到）但这是可能的只有在目标数不是的情况下？ - ？，因为没有任何目标。
我希望你能理解我......
致以最诚挚的问候，非常感谢您的帮助，
马

以下搜索仅匹配您的链接：
import re
links = soup.find_all('a', class_='scorelink', href=True,
text=re.compile('\d+ - \d+'))
搜索仅限于：
<a>标签scorelink href属性只提取链接是微不足道的：
score_urls = [link['href'] for link in soup.find_all(
'a', class_='scorelink', href=True, text=re.compile('\d+ - \d+'))]
演示：
>>> from bs4 import BeautifulSoup
>>> import requests
>>> from pprint import pprint
>>> soup = BeautifulSoup(requests.get('http://www.livescore.com/soccer/champions-league/').content)
>>> [link['href'] for link in soup.find_all('a', class_='scorelink', href=True, text=re.compile('\d+ - \d+'))]

在BeautifulSoup之外很容易做到。首先找到所有链接，然后过滤掉返回? - ?文本的链接，然后从清理列表中的每个项目中获取href属性。见下文。
In [1]: from bs4 import BeautifulSoup as bsoup
In [2]: import requests as rq
In [3]: url = "http://www.livescore.com/soccer/champions-league/"
In [4]: r = rq.get(url)
In [5]: bs = bsoup(r.text)
In [6]: links = bs.find_all("a", class_="scorelink")
In [7]: links
Out[7]:
[<a class="scorelink" href="/soccer/champions-league/group-a/atletico-madrid-vs-malmo-ff/1-1821150/" onclick="return false;">? - ?</a>,
<a class="scorelink" href="/soccer/champions-league/group-a/olympiakos-vs-juventus/1-1821151/" onclick="return false;">? - ?</a>,
...
In [8]: links_clean = [link for link in links if link.get_text() != "? - ?"]
In [9]: links_clean
Out[9]:
[<a class="scorelink" href="/soccer/champions-league/group-e/cska-moscow-vs-manchester-city/1-1821202/" onclick="return false;">0 - 1</a>,
<a class="scorelink" href="/soccer/champions-league/qualifying-round/zenit-st-petersburg-vs-standard-liege/1-1801440/" onclick="return false;">3 - 0</a>,
...
In [10]: links_final = [link["href"] for link in links_clean]
In [11]: links_final
Out[11]:
['/soccer/champions-league/group-e/cska-moscow-vs-manchester-city/1-1821202/',
'/soccer/champions-league/qualifying-round/zenit-st-petersburg-vs-standard-liege/1-1801440/',

从每个链接中提取分钟当然取决于您。
