使用BeautifulSoup获取标签样式

python

我正在抓取页面,并从该页面上的表中获取所有<tr>元素,如下所示:

r = requests.get("http://lol.esportswikis.com/wiki/G2_Esports/Match_History")
s = BeautifulSoup(r.content, "lxml")
tr = s.find_all("table", class_="wikitable sortable")[0].find_all("tr")[3:]

print tr[0]

输出:

<tr style="background-color:#C6EFCE"><td>...</td> ... <td>...</td></tr>

现在,我试图获取<tr>标签的样式,但是我不知道如何。例如,如果我这样做:

for item in tr[0]:
    print item

它显然只是打印<td> ... </td>东西。我想我大概可以做这样的事情print tr[0].something,比如tr[0].tag,但一切到目前为止,我已经尝试并没有带来我想要的东西。

只需使用以下属性即可访问tag["attribute"]

In [28]: soup = BeautifulSoup('<tr style="pretty"></tr>', 'html.parser')

In [29]: print soup.find("tr")["style"]
pretty

如果您只想要具有样式属性an的tr标记来获取全部标记:

trs = s.find("table", class_="example-table").find_all("tr", style=True)

for tr in trs:
    print(tr["style"])

或使用CSS选择器:

trs = s.select("table.example-table tr[style]")

for tr in trs:
    print(tr["style"])

使用您的实际网址:

In [41]: r = requests.get("http://lol.esportswikis.com/wiki/G2_Esports/Match_History")

In [42]: s = BeautifulSoup(r.content, "lxml")

In [43]: trs = s.select("table.wikitable.sortable tr[style]")

In [44]:

In [44]: for tr in trs:
   ....:         print(tr["style"])
   ....:
