Question

我正在尝试解析标记<blockquote>之间的文本。当我输入soup.blockquote.get_text()时。

我得到了HTML文件中第一个出现的blockquote所需的结果。如何在文件中找到下一个和顺序<blockquote>标记？也许我只是累了，在文档中找不到它。

示例HTML文件：

<html>
<head>header
</head>
<blockquote>I can get this text
</blockquote>
<p>eiaoiefj</p>
<blockquote>trying to capture this next
</blockquote>
<p></p><strong>do not capture this</strong>
<blockquote>
capture this too but separately after "capture this next"
</blockquote>
</html>

简单的python代码：

from bs4 import BeautifulSoup

html_doc = open("example.html")
soup = BeautifulSoup(html_doc)
print.(soup.blockquote.get_text())
# how to get the next blockquote???

Answer 1

使用find_next_sibling（如果不是兄弟，请改用find_next）

>>> html = '''
... <html>
... <head>header
... </head>
... <blockquote>blah blah
... </blockquote>
... <p>eiaoiefj</p>
... <blockquote>capture this next
... </blockquote>
... <p></p><strong>don'tcapturethis</strong>
... <blockquote>
... capture this too but separately after "capture this next"
... </blockquote>
... </html>
... '''

>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup(html)
>>> quote1 = soup.blockquote
>>> quote1.text
u'blah blah\n'
>>> quote2 = quote1.find_next_siblings('blockquote')
>>> quote2.text
u'capture this next\n'

使用Beautiful Soup查找下一个出现的标签及其附带的文本
