给定一个 html 页面源，例如:
<html>
<head></head>
<body>
<p><nobr><a href="...">Some link text</a></nobr><p>
</body>
</html>
并且没有明确知道什么标签包装了 <a>元素(可以是任何东西，而不仅仅是 nobr)。如何创建一个循环来不断展开给定 <a> 的父级标签直到其父级是一个段落？
类似于:
import urllib3
from bs4 import BeautifulSoup as bs
http = urllib3.PoolManager()
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
page = "https://www.snopes.com/fact-check/rebuilding-iraq/"
link="http://www.elca.org/ScriptLib/OS/Congregations/cdsDetail.asp?congrno=12962"
r = http.request('get', page)
body = r.data
soup = bs(body, 'lxml')
a = soup.find('a', href=link)
while True:
if a.parent.name == "p":
break
else:
a.parent.name.unwrap() #doesnt work as name is string
print(soup)
最佳答案
使用find_parents作为给定的子标签。
import requests
from bs4 import BeautifulSoup
page = "https://www.snopes.com/fact-check/rebuilding-iraq/"
link="http://www.elca.org/ScriptLib/OS/Congregations/cdsDetail.asp?congrno=12962"
r = requests.get(page)
soup = bs(r.content, 'lxml')
a = soup.find('a', href=link)
for tag in a.find_parents('p'):
print(tag)
输出:
<p><font class="copyright_text_color" color="" face=""><b>Origins:</b></font> This item is “true” in the sense that Eric Rydbom is indeed an engineer stationed in Iraq with the Army’s <nobr>4th Infantry</nobr> Division, and he sends monthly <nobr>e-mail</nobr> dispatches such as the one quoted above to fellow members of his congregation at the <nobr><a href="http://www.elca.org/ScriptLib/OS/Congregations/cdsDetail.asp?congrno=12962" target="_blank">First Lutheran</a></nobr> Church of Richmond Beach in Shorline, Washington. This piece was one of those messages, forwarded to the church’s prayer chain and thence to the larger world via the Internet.</p>
如果你想获取文本，只需使用。
for tag in a.find_parents('p'):
print(tag.text)
