`......<div class="thesaurus" type="tabt"><div class="beigeBox">......</div><div class="entry">......</div></div>......`

我用bs搞的, 你用的什么解析器? 试试lxml呢.

正则的话, 我只能分两步搞, 先匹配到thesaurus标签, 再提取text

```auto
thesaurus_tag = re.compile(r'<div\s+class=\"thesaurus\".*?>\s+<div\s+class=\"entry\">.*?</div>\s+</div>', re.DOTALL)
unwanted = re.compile(r"<(?:\"[^\"]*\"['\"]*|'[^']*'['\"]*|[^'\">])+>", re.DOTALL)

```

或者你试试先匹配出thesaurus标签, 再用bs提取文字, thesaurus标签其实没有几个

我就随手用的html.parser，效率会差很多吗，大意了啊，7个g花了好几个小时 🥲下次再试试你的方法

会差很多。

`pip install lxml`

然后代码里面：

`soup = BeautifulSoup(html, 'lxml')`

学到了，是我自作聪明了，看网上别人也都是用lxml 😅
