regular expression to add characters before and after numbers

问题

I have a list of numbers between square brackets, and I need to add words before and after the exact numbers (i.e. keep the same numbers). I use notepad++ to replace, but if you have a solution with other program please advise.

Example:

text [121] othertext
moretext [16] othertextmore
andtext [5940] othertextplus

outcome:

text xxxxxxxxx [121] xxxxxxxxx othertext
moretext xxxxxxxxx [16] xxxxxxxxx othertextmore
andtext xxxxxxxxx [5940] xxxxxxxxx othertextplus

The numbers are of course \d+ but I want to tell it to keep the same numbers when looking.

回答1:

Find What: (\[\d+])

Replace With: xxxxxxxxx \1 xxxxxxxxx

回答2:

C#:

line=Regex.Replace(line,@"([^\[])(\[\d+\])(.*)","$1xxxxxxxxx $2 xxxxxxxxx$3");

Other languages analogous

回答3:

Regular expression:

Find regex = \[\d+\]
Replace regex = xxxxxxxxx$&xxxxxxxxx
