使用正则表达式删除重复括号之间的内容

Question

I'm trying to remove unneeded words between brackets that contains certain modifier ('DeleteMe') and don't delete contents between brackets that contains other words ('DontDeleteMe'). I though it was simple but proved difficult due to repeating brackets see below.

[
aljdsfjfldsa      DeleteMe         aldsjflajdf
]
[
aldskjfal         DontDeleteMe     asdlkjflasdj
]
[
aljdsfjfldsa      DeleteMe         aldsjflajdf
]
[
aldskjfal         DontDeleteMe     asdlkjflasdj
]

Desired output

[
aldskjfal         DontDeleteMe     asdlkjflasdj
]
[
aldskjfal         DontDeleteMe     asdlkjflasdj
]

I tried the following but the problem is the second line will be deleted with the third line.

(?s)\[.*?'DeleteMe'.*?\]

Answer 1

You can use a word boundary in combination with a negated character class [^

\[[^][]*\bDontDeleteMe\b[^][]*\]

If the word is DeleteMe you can match it using word boundaries and repace with an empty string.

\[[^][]*\bDeleteMe\b[^][]*\]
