正则很难实现，建议用python+bs

送伊一颗小
原来如此，我在网上找半天没找到
找一个xml解析的工具或相关的库，很好处理的

可能是因为我的文件没写全，你给的正则不行，我传上来可以麻烦再看看吗

是这种结果，正则没看到 
效率如何，差不多7g，我用python+bs花了好几个小时（代码很简陋）
这个是正则写出来的吗
不知……我对这个一窍不通的。

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
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
