是否可以用美丽的汤来提取多种类型的物品？

我一直在查看文档，但他们没有涵盖这个问题。我正在尝试提取所有文本和所有链接，但不是单独提取。我希望它们交错以保留上下文。我想最终得到一个文本和链接的交错列表。 BeautifulSoup 可以做到这一点吗？

是的，这绝对是可能的。

import urllib2
import BeautifulSoup

request = urllib2.Request("http://www.example.com")
response = urllib2.urlopen(request)
soup = BeautifulSoup.BeautifulSoup(response)
for a in soup.findAll('a'):
    print a

分解此代码片段，您正在向网站（在本例中为 Google.com）发出请求，并使用 BeautifulSoup 解析响应。您的要求是找到所有链接和文本并保留上下文。上述代码的输出将如下所示：

<a href="/"><img src="/_img/iana-logo-pageheader.png" alt="Homepage" /></a>
<a href="/domains/">Domains</a>
<a href="/numbers/">Numbers</a>
<a href="/protocols/">Protocols</a>
<a href="/about/">About IANA</a>
<a href="/go/rfc2606">RFC 2606</a>
<a href="/about/">About</a>
<a href="/about/presentations/">Presentations</a>
<a href="/about/performance/">Performance</a>
<a href="/reports/">Reports</a>
<a href="/domains/">Domains</a>
<a href="/domains/root/">Root Zone</a>
<a href="/domains/int/">.INT</a>
<a href="/domains/arpa/">.ARPA</a>
<a href="/domains/idn-tables/">IDN Repository</a>
<a href="/protocols/">Protocols</a>
<a href="/numbers/">Number Resources</a>
<a href="/abuse/">Abuse Information</a>

Yes, this is definitely possible.

import urllib2
import BeautifulSoup

request = urllib2.Request("http://www.example.com")
response = urllib2.urlopen(request)
soup = BeautifulSoup.BeautifulSoup(response)
for a in soup.findAll('a'):
    print a

Breaking this code snippet down, you are making a request for a website (in this case Google.com) and parsing the response back with BeautifulSoup. Your requirements were to find all links and text and keep the context. The output of the above code will look like this:

<a href="/"><img src="/_img/iana-logo-pageheader.png" alt="Homepage" /></a>
<a href="/domains/">Domains</a>
<a href="/numbers/">Numbers</a>
<a href="/protocols/">Protocols</a>
<a href="/about/">About IANA</a>
<a href="/go/rfc2606">RFC 2606</a>
<a href="/about/">About</a>
<a href="/about/presentations/">Presentations</a>
<a href="/about/performance/">Performance</a>
<a href="/reports/">Reports</a>
<a href="/domains/">Domains</a>
<a href="/domains/root/">Root Zone</a>
<a href="/domains/int/">.INT</a>
<a href="/domains/arpa/">.ARPA</a>
<a href="/domains/idn-tables/">IDN Repository</a>
<a href="/protocols/">Protocols</a>
<a href="/numbers/">Number Resources</a>
<a href="/abuse/">Abuse Information</a>
