如何在BeautifulSoup中删除空格 [英] How to remove whitespace in BeautifulSoup

问题描述

我有一堆正在用BeautifulSoup解析的HTML，除了一个小问题外，它运行得很好.我想将输出保存到单行字符串中，并将以下内容作为当前输出:

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>

理想情况下我想

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

我想摆脱很多多余的空格，但不一定可以使用strip()将其删除，也不能因为需要保留文本而公然删除所有空格.我该怎么做?似乎很常见的问题是，正则表达式可能会造成过大的杀伤力，但这是唯一的方法吗?

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?

我没有任何<pre>标记，所以在那里我可以变得更有力.

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

再次感谢！

推荐答案

以下是不使用正则表达式的方法:

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("\n"))
>>> 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>'
