BeautifulSoup 4, findNext() function
提问by nutship
I'm playing with BeautifulSoup 4 and I have this html code:
我在玩 BeautifulSoup 4，我有这个 html 代码：
</tr>
<tr>
<td id="freistoesse">Giraffe</td>
<td>14</td>
<td>7</td>
</tr>
I want to match both values between <td>tags so here 14 and 7.
我想匹配<td>标签之间的两个值，所以这里是 14 和 7。
I tried this:
我试过这个：
giraffe = soup.find(text='Giraffe').findNext('td').text
but this only matches 14. How can I match both values with this function?
但这仅匹配14. 如何将这两个值与此函数匹配？

Use find_allinstead of findNext:
使用find_all代替findNext：
import bs4 as bs
content = '''\
<tr>
<td id="freistoesse">Giraffe</td>
<td>14</td>
<td>7</td>
</tr>'''
soup = bs.BeautifulSoup(content)
for td in soup.find('td', text='Giraffe').parent.find_all('td'):
print(td.text)
yields
产量
Giraffe
14
7
Or, you could use find_next_siblings(also known as fetchNextSiblings):
或者，您可以使用find_next_siblings（也称为fetchNextSiblings）：
for td in soup.find(text='Giraffe').parent.find_next_siblings():
print(td.text)
yields
产量
14
7
Explanation:
解释：
Note that soup.find(text='Giraffe')returns a NavigableString.
请注意，soup.find(text='Giraffe')返回一个 NavigableString。
In [30]: soup.find(text='Giraffe')
Out[30]: u'Giraffe'
To get the associated tdtag, use
要获取关联的td标签，请使用
In [31]: soup.find('td', text='Giraffe')
Out[31]: <td id="freistoesse">Giraffe</td>
or
或者
In [32]: soup.find(text='Giraffe').parent
Out[32]: <td id="freistoesse">Giraffe</td>
Once you have the tdtag, you could use find_next_siblings:
获得td标签后，您可以使用find_next_siblings：
In [35]: soup.find(text='Giraffe').parent.find_next_siblings()
Out[35]: [<td>14</td>, <td>7</td>]
PS. BeautifulSoup has added method names that use underscores instead of CamelCase. They do the same thing, but comform to the PEP8 style guide recommendations. Thus, prefer find_next_siblingsover fetchNextSiblings.
附注。BeautifulSoup 添加了使用下划线代替 CamelCase 的方法名称。他们做同样的事情，但符合 PEP8 风格指南的建议。因此，喜欢find_next_siblings过fetchNextSiblings。
