How to extract commas in between square brackets in notepad++?

问题

For example:

[TEXT1,TEXT2,TEXT3]

my expression: [\[].*,.*[\]]

Finds strings with commas (in between brackets,) but I only want to explicitly match the comma that exists in the square brackets.

I need to replace the commas with spaces - but only in the square brackets.

I've tried [\[],[\]] but that doesn't work -

\[(.*?)\] will find the text in between as well - but I do not want the entire string.

Can anyone suggest what I need to do to just find commas in between the brackets?

回答1:

Find what:

(?:\[|(?!^)\G)[^,\]]*\K,

Replace with:
space

---

Break-down:

• (?:\[|(?!^)\G) Matches the opening [ or the end of last match (?!^)\G.
• [^,\]]* Consumes all chars until the next comma.
• \K Tells the regex engine to discard what it has matched so far.
• , Finally matches the comma.

I know this is an old question but I was looking to solve this same issue and found a solution with this: ,(?=[^\[]*\])

I hope it helps someone who stumbles on this post! 🙂

Note: Using Text Wrangler instead of Notepad++

回答3:

Square brackets generally need to be escaped in regex, so something like

\[.*(,).*\] 

could work - where the regex group #1 (which is the captured/replaceable part in other tools, I don't have notepad++) would be the single comma in brackets that you want.

I used this:

(?<=[\[,])[^\],]*(,)
