我正在抓取一个页面,并从该页面上的表格中获取所有<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>
现在我正试图获得<tr>
标签的样式,但我不知道如何。如果我这样做:
for item in tr[0]:
print item
它显然只是打印<td> ... </td>
的东西。我想我可能会做像print tr[0].something
这样的事情,比如tr[0].tag
,但到目前为止我所尝试的一切都没有达到我想要的效果。

只需使用tag["attribute"]
访问该属性:
In [28]: soup = BeautifulSoup('<tr style="pretty"></tr>', 'html.parser')
In [29]: print soup.find("tr")["style"]
pretty
如果你只想要带有样式属性的tr标签来获取它们:
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"])
