如何用BeautifulSoup解除HTML注释包裹的内容?

如何用BeautifulSoup高效提取被HTML注释包裹的目标元素

我正在使用bs4 4.10.0版本的BeautifulSoup进行网页爬取,遇到一个问题:部分目标元素被HTML注释包裹,需要将注释内的HTML节点还原为正常可解析的节点,而非删除注释内容。

原始HTML示例

<div class="h-[125] js-scroll-hidden" id="link-index-40">

<!--            <a href="/md5/dc0bbd5373a5ada24373640dab8defb3" class="custom-a flex items-center relative left-[-10] px-[10] py-2 hover:bg-[#00000011] ">
              <div class="flex-none">
                <div class="relative overflow-hidden w-[72] h-[108] flex flex-col justify-center">
                  <div class="absolute w-[100%] h-[90]" style="background-color: hsl(63deg 43% 73%)"></div>
                  <img class="relative inline-block" src="https://libgen.rs/covers/2274000/dc0bbd5373a5ada24373640dab8defb3-g.jpg" alt="" referrerpolicy="no-referrer" onerror="this.parentNode.removeChild(this)" loading="lazy" decoding="async"/>
                </div>
              </div>
              <div class="relative top-[-1] pl-4 grow overflow-hidden">
                <div class="truncate text-xs text-gray-500">English [en], pdf, 11.7MB, &#34;The Dale Carnegie course in effective spea - Dale Carnegie.pdf&#34;</div>
                <h3 class="truncate text-xl font-bold">The Dale Carnegie course in effective speaking, human relations and developing courage and confidence, improving your memory, leadership training : how the course is conducted and what you do at each session</h3>
                <div class="truncate text-sm">Dale Carnegie, 1989</div>
                <div class="truncate italic">Dale Carnegie &amp; Associates, Inc.</div>
              </div>
            </a>

--> </div>

已尝试的方案

  • 搜索到的多数方案是直接移除注释内容,不符合我的需求
  • 尝试修改标签内容,但会破坏后续需要使用的.find()和.find_all()方法
  • 手动处理注释符号,但未找到可行的方式
  • 现有可行方法资源消耗过大,而我需要处理200+这类元素,希望找到高效实现方式

期望结果

<div class="h-[125] js-scroll-hidden" id="link-index-40">

            <a href="/md5/dc0bbd5373a5ada24373640dab8defb3" class="custom-a flex items-center relative left-[-10] px-[10] py-2 hover:bg-[#00000011] ">
              <div class="flex-none">
                <div class="relative overflow-hidden w-[72] h-[108] flex flex-col justify-center">
                  <div class="absolute w-[100%] h-[90]" style="background-color: hsl(63deg 43% 73%)"></div>
                  <img class="relative inline-block" src="https://libgen.rs/covers/2274000/dc0bbd5373a5ada24373640dab8defb3-g.jpg" alt="" referrerpolicy="no-referrer" onerror="this.parentNode.removeChild(this)" loading="lazy" decoding="async"/>
                </div>
              </div>
              <div class="relative top-[-1] pl-4 grow overflow-hidden">
                <div class="truncate text-xs text-gray-500">English [en], pdf, 11.7MB, &#34;The Dale Carnegie course in effective spea - Dale Carnegie.pdf&#34;</div>
                <h3 class="truncate text-xl font-bold">The Dale Carnegie course in effective speaking, human relations and developing courage and confidence, improving your memory, leadership training : how the course is conducted and what you do at each session</h3>
                <div class="truncate text-sm">Dale Carnegie, 1989</div>
                <div class="truncate italic">Dale Carnegie &amp; Associates, Inc.</div>
              </div>
            </a>

</div>

请问是否有BeautifulSoup原生、低资源消耗的方法实现上述需求?也可推荐其他易用工具。
