如何去除 BeautifulSoup 中的空格 [英] How to remove whitespace in BeautifulSoup

问题描述

我有一堆 HTML 正在用 BeautifulSoup 进行解析，除了一个小问题外，一切进展顺利.我想将输出保存为单行字符串，以下是我当前的输出:

 
Zazzafooky 但一二三！</span></li><li><span class="plaincharacterwrap break">Zazzafooky2</span></li><li><span class="plaincharacterwrap break">Zazzafooky3</span></li>

理想情况下我愿意

<li><span class="plaincharacterwrap break">Zazzaooky 但一二三！</span></li><li><span class="plaincharacterwrap break">Zazzafooky2</span></li>

有很多多余的空格我想去掉，但不一定可以使用 strip() 去除，我也不能公然删除所有空格，因为我需要保留文本.我该怎么做?正则表达式似乎是一个足够普遍的问题，但这是唯一的方法吗?

我没有任何 <pre> 标签，所以我可以在那里更有力一些.

再次感谢！

解决方案

以下是不使用正则表达式的方法:

<预><代码>>>>html = """

... Zazzafooky 但一二三！... </span></li>... <li><span class="plaincharacterwrap break">... Zazzafooky2... </span></li>... <li><span class="plaincharacterwrap break">... Zazzafooky3... </span></li>……">>>html = "".join(line.strip() for line in html.split(" "))>>>html'<li><span class="plaincharacterwrap break">Zazzaooky 但一二三！</span></li><li><span class="plaincharacterwrap break">Zazzafooky2</span></li><li><span class="plaincharacterwrap break">Zazzafooky3</span></li>'

I have a bunch of HTML I'm parsing with BeautifulSoup and it's been going pretty well except for one minor snag. I want to save the output into a single-lined string, with the following as my current output:

    <li><span class="plaincharacterwrap break">
                    Zazzafooky but one two three!
                </span></li>
<li><span class="plaincharacterwrap break">
                    Zazzafooky2
                </span></li>
<li><span class="plaincharacterwrap break">
                    Zazzafooky3
                </span></li>

Ideally I'd like

<li><span class="plaincharacterwrap break">Zazzafooky but one two three!</span></li><li><span class="plaincharacterwrap break">Zazzafooky2</span></li>

There's a lot of redundant whitespace that I'd like to get rid of but it's not necessarily removable using strip(), nor can I blatantly remove all the spaces because I need to retain the text. How can I do it? It seems like a common enough problem that regex would be overkill, but is that the only way?

I don't have any <pre> tags so I can be a little more forceful there.

Thanks once again!

解决方案

Here is how you can do it without regular expressions:

>>> html = """    <li><span class="plaincharacterwrap break">
...                     Zazzafooky but one two three!
...                 </span></li>
... <li><span class="plaincharacterwrap break">
...                     Zazzafooky2
...                 </span></li>
... <li><span class="plaincharacterwrap break">
...                     Zazzafooky3
...                 </span></li>
... """
>>> html = "".join(line.strip() for line in html.split("
"))
>>> html
'<li><span class="plaincharacterwrap break">Zazzafooky but one two three!</span></li><li><span class="plaincharacterwrap break">Zazzafooky2</span></li><li><span class="plaincharacterwrap break">Zazzafooky3</span></li>'
