BeautifulSoup 4，findNext()函数 [英] BeautifulSoup 4, findNext() function

问题描述

我正在使用BeautifulSoup 4，并且我有以下html代码:

I'm playing with BeautifulSoup 4 and I have this html code:

</tr>
          <tr>
<td id="freistoesse">Giraffe</td>
<td>14</td>
<td>7</td>
</tr>

我想匹配<td>标签之间的两个值，因此这里是14和7.

I want to match both values between <td> tags so here 14 and 7.

我尝试过:

giraffe = soup.find(text='Giraffe').findNext('td').text

，但这仅匹配14.如何将两个值与此函数匹配?

but this only matches 14. How can I match both values with this function?

推荐答案

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)

收益

Giraffe
14
7

或者，您可以使用find_next_siblings(也称为fetchNextSiblings):

---

Or, you could use find_next_siblings (also known as fetchNextSiblings):

for td in soup.find(text='Giraffe').parent.find_next_siblings():
    print(td.text)

收益

14
7

说明:

请注意，soup.find(text='Giraffe')返回NavigableString.

Note that soup.find(text='Giraffe') returns a NavigableString.

In [30]: soup.find(text='Giraffe')
Out[30]: u'Giraffe'

要获取关联的td标签，请使用

To get the associated td tag, use

In [31]: soup.find('td', text='Giraffe')
Out[31]: <td id="freistoesse">Giraffe</td>

或

In [32]: soup.find(text='Giraffe').parent
Out[32]: <td id="freistoesse">Giraffe</td>

一旦有了td标记，就可以使用find_next_siblings:

Once you have the td tag, you could use find_next_siblings:

In [35]: soup.find(text='Giraffe').parent.find_next_siblings()
Out[35]: [<td>14</td>, <td>7</td>]

PS. BeautifulSoup添加了使用下划线而不是CamelCase的方法名称.它们执行相同的操作，但符合PEP8样式指南的建议.因此，与fetchNextSiblings相比，更优选find_next_siblings.

---

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_siblings over fetchNextSiblings.
