How to add space around removed tags in BeautifulSoup

Question

from BeautifulSoup import BeautifulSoup

html = '''<div class="thisText">
Poem <a href="http://famouspoetsandpoems.com/poets/edgar_allan_poe/poems/18848">The Raven</a>Once upon a midnight dreary, while I pondered, weak and weary... </div>

<div class="thisText">
In the greenest of our valleys By good angels tenanted..., part of<a href="http://famouspoetsandpoems.com/poets/edgar_allan_poe/poems/18848">The Haunted Palace</a>
</div>'''


soup = BeautifulSoup(html)
all_poems = soup.findAll("div", {"class": "thisText"})
for poems in all_poems:
print(poems.text)

I have this sample code and i cant find how to add spaces around the removed tags so when the text inside the <a href...> get formatted it can be readable and wont display like this:

PoemThe RavenOnce upon a midnight dreary, while I pondered, weak and weary...

Answer 1

一种选择是找到所有文本节点并用空格连接它们：

" ".join(item.strip() for item in poems.find_all(text=True))

此外，您正在使用已过时且未维护的beautifulsoup3包。升级到beautifulsoup4：

pip install beautifulsoup4

并替换：

from BeautifulSoup import BeautifulSoup

使用：

from bs4 import BeautifulSoup

Answer 2

get_text()中的

beautifoulsoup4具有可选输入separator。您可以按以下方式使用它：

soup = BeautifulSoup(html)
text = soup.get_text(separator=' ')

Answer 3

此处使用lxml及其xpath函数替代搜索所有文本节点：

from lxml import etree

html = '''<div class="thisText">
Poem <a href="http://famouspoetsandpoems.com/poets/edgar_allan_poe/poems/18848">The Raven</a>Once upon a midnight dreary, while I pondered, weak and weary... </div>

<div class="thisText">
In the greenest of our valleys By good angels tenanted..., part of<a href="http://famouspoetsandpoems.com/poets/edgar_allan_poe/poems/18848">The Haunted Palace</a>
</div>'''

root = etree.fromstring(html, etree.HTMLParser())
print(' '.join(root.xpath("//text()")))

它产生：

Poem  The Raven Once upon a midnight dreary, while I pondered, weak and weary...
