Python：删除两个给定 HTML 标签之间的所有内容

Question

选择的编程语言是Python。 这是我的 HTML 文本：

<a href="https://www.example.com">Original message</a><br>
<ul id="list">
    <li class="blockbody" id="post_1">
        <div class="header">
            <div class="datetime">
                24 januari 2020, 11:34
            </div><span class="name">Jane Doe</span>
        </div>
        <div class="content">
            <blockquote class="restore">
                <div class="bbcode_container">
                    <i class="fa fa-envelope"></i> Citation:
                    <div class="bbcode_quote printable">
                        <hr>
                        <div>
                            Citation: John Doe <a href="showthread.php#post684209" rel="nofollow"><img alt="" class="inlineimg" src="image/style/Aesthetica/button/view.gif"></a>
                        </div>
                        <div class="message">
                            Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

                        </div>
                        <hr>
                    </div>
                </div><br>
                <div class="bbcode_container">
                    <i class="fa fa-envelope"></i> Citation:
                    <div class="bbcode_quote printable">
                        <hr>

                        <br>
                        Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam.<br>
                        <br>
                        quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum..
                        <hr>
                    </div>
                </div>... <a href="https://example.com" target="_blank">https://example.html</a><br>
                <br>
                velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum?
            </blockquote>
        </div>
    </li>
</ul>

我想删除 THE FIRST

<div class="bbcode_quote printable">

和 THE LAST

<hr>

标签之间的所有内容。正如您所看到的，这两个标签都有多个实例，这就是为什么我强调第一个和最后一个。 我熟悉 Python，但字符串操作不是我的专业领域。 我希望我已经说清楚了。

您可以使用 Beautiful Soup 库 - https://pypi.org/project/beautifulsoup4/

参考：

• 使用BeautifulSoup查找具有两种特定样式的标签
• 如何删除特定 html 标签内的所有内容（以及标签本身）
