Python Regex：匹配任何不包括2个单词的文本（可能环顾四周）
我正在尝试制作与这样匹配标签的正则（这样我可以用空白代替它们）：
{# This is a comment #}
{% if cows > pandas %}
{{ my_variable }}
但是，如果标签中的第一个单词是或扩展了，则不得匹配标签（它将始终与{％％}令牌配对。
例如，
{% include 'foo.html' %}
{% extends 'foo/bar/baz.html' %}
我有以下Python Regex，
{[{#%]\s*.*?(?!include|extends)[}#%]}
但是负面断言不起作用（例如，以下匹配和排除在下面）：
{# match this #}
{% match this %}
{{ match this }}
asdf
{% foo 'match this' %} asdf {% foo 'match this' %} asdf
{% include 'not this' %}
{% extends 'not this' %}
asdf
注意：是的，如果您有兴趣，这与django templating有关！
I am trying to make a regex that matches tags like this (so I can substitute them with blanks):
{# This is a comment #}
{% if cows > pandas %}
{{ my_variable }}
However if the first word in the tags is includes or extends then it must not match the tag (it will always be paired with {% %} tokens fyi).
e.g.
{% include 'foo.html' %}
{% extends 'foo/bar/baz.html' %}
I have the following python regex
{[{#%]\s*.*?(?!include|extends)[}#%]}
However the negative assertion is not working (i.e include and exclude are matched below):
{# match this #}
{% match this %}
{{ match this }}
asdf
{% foo 'match this' %} asdf {% foo 'match this' %} asdf
{% include 'not this' %}
{% extends 'not this' %}
asdf
Note: Yes this is to do with Django templating if you are interested!

您可以使用

详细信息：
{- a{char[{＃％]- a{，＃或％char（？！\ s*（？inclage |扩展）如果有零或以上的空格，则单词延伸为include或将单词作为当前位置的右侧> [}＃％]- a}，＃或％< /code> char}- a}char。You can use
See the regex demo.
Details:
{- a{char[{#%]- a{,#or%char(?!\s*(?:include|extends)\b)- a negative lookahead that fails the match if there are zero or more whitespaces followed withincludeorextendswords as whole words immediately to the right of the current location.*?- any zero or more chars other than line break chars as few as possible[}#%]- a},#or%char}- a}char.
