英文:
Regex to match all occurrences but ignore if it starts with vendor
问题
我试图编写一个正则表达式来匹配所有的 anystring/css/，但是要排除 vendor/css/，例如：
apples/css/
vendor/css/
kiwi/css/
Apple/css/
vendor/css/
应该匹配的是：
apples/css/
kiwi/css/
Apple/css/
我尝试了以下正则表达式，但它并没有正确工作，只忽略了第一个 vendor/css/，而不是其他的：
\b[^(vendor)].+\/css\/
英文:
I'm trying to do a regex to match to find and match all anystring/css/ except vendor/css/ for example
apples/css/
vendor/css/
kiwi/css/
Apple/css/
vendor/css/
should match
apples/css/
kiwi/css/
Apple/css/
i was able to come up with but its not working correctly and only ignores the first vendor/css/ but not the others
\b[^(vendor)].+\/css\/

[^(vendor)] 表示任何不是以下字符之一的字符：(、v、e、n、d、o、r、)。这不会按您期望的工作。
为了匹配不以名为vendor的文件夹开头的目录（？），请使用负向先行断言：
\b # 匹配词边界，然后
(?!vendor\/) # 不以 'vendor/' 开头，
.+ # 任何不包含
\/css\/ # 后跟 '/css/'。
这会匹配：
apples/css/
kiwi/css/
Apple/css/
endor/css/
venv/css/
foo/bar/css/
lorem/css/ipsum/css/
dolor/sit/amet/vendor/css/
vendors/css/
baz/css/qux
但不会匹配：
vendor/css/
为了限制整行只有两个级别，使用：
^ # 在行首，匹配一个字符串
(?!vendor\/) # 不是 'vendor/'，
[^\/]+\/ # 由1个或多个非斜杠杠字符，然后是斜杠杠，
css\/ # 后跟 'css/'
$ # 紧挨着行尾。
这会匹配：
apples/css/
kiwi/css/
Apple/css/
endor/css/
venv/css/
vendors/css/
但不会匹配：
foo/bar/css/
lorem/css/ipsum/css/
dolor/sit/amet/vendor/css/
baz/css/qux
vendor/css/
英文:
[^(vendor)] means any character that is not one of (, v, e, n, d, o, r, ). This wouldn't work as you expected.
To match directories (?) that doesn't start with a folder named vendor, use negative lookahead:
\b # Match a word boundary, then
(?!vendor\/) # start with 'vendor/',
.+ # anything that does not
\/css\/ # followed by '/css/'.
This matches:
apples/css/
kiwi/css/
Apple/css/
endor/css/
venv/css/
foo/bar/css/
lorem/css/ipsum/css/
dolor/sit/amet/vendor/css/
vendors/css/
baz/css/qux
...but not:
vendor/css/
Try it on regex101.com.
To limit the whole line to two levels, use:
^ # At the beginning of line, match a string that
(?!vendor\/) # is not 'vendor/',
[^\/]+\/ # and consists of 1+ non-slash characters, then a slash,
css\/ # followed by 'css/'
$ # right before the end of line.
This matches:
apples/css/
kiwi/css/
Apple/css/
endor/css/
venv/css/
vendors/css/
...but not:
foo/bar/css/
lorem/css/ipsum/css/
dolor/sit/amet/vendor/css/
baz/css/qux
vendor/css/
