I have this String test = "elevation[value1,value2],temperature[value2,value3],radiance[value4,value5]..."

I would like to split each , not contained between square brackets. To get something like [ [elevation[value1,value2]] , [temperature[value2,value3]] , [radiance[value4,value5]] ]

I mean each element will be like elevation[value1,value2]

I am really not confortable using regex, if someone can help me.

CodePudding user response：

You can target each comma that is not contained within brackets using following regex but assuming your brackets will have to be balanced.

,(?![^\[]*\])

and split to get your desired results.

Explanation:

• , - Match a comma
• (?![^\[]*\]) - This negative lookahead ensures that there is no ] character directly without an [ opening bracket.
