I m azak-regex newbie, so有我......
我有很长的多线插座,在座中,我必须替换[[...]]的目录。 跟着其他 st子,但仅凭FonLY,他们并不开始档案http:// ,例如:
s= chk1 [[file:///excursions/digital/MindMaps/|mm]],
local file [[file:///inFolder/tmptest/a/fan.txt|a/fan.txt]]
and nonlocal [[/excursions/books/calsync.txt|/excursions/books]]
我使用了这种差异(此时,替代体只是检查我发现的情况):
re.sub( [[(?!file:)(^])* ,"found:< \1 >",s)
但是,我收到了“sre_constants.error: unmatled group”。 你们是否知道我做错了什么?
感谢!

You re missing the [] operator in the second group:
[[(?!file:)(^])*
应当:
[[(?!file:)([^]]*)
如果你有许多生态环境,那么最好使用原体:
re.sub(r [[(?!file:)([^]]*) , r"found:<1>", s)
你的方括号由于 escaping而未定。
