BeautifulSoup 保留一些文本，但删除标签的其余部分

Question

我正在使用一个从论坛抓取数据的机器人。我这里有这个可以使用：

<description><![CDATA[ <p>This is a test post with a few emotes <img src="https://sjc5.discourse-cdn.com/try/images/emoji/twitter/grin.png?v=9" title=":grin:" class="emoji" alt=":grin:"> <img src="https://sjc5.discourse-cdn.com/try/images/emoji/twitter/heart.png?v=9" title=":heart:" class="emoji" alt=":heart:"></p> ]]></description>

从此我想得到

This is a test post with a few emotes :grin: :heart:

我该怎么做呢？如果表情也位于文本中间，我也希望能够做到这一点。
