I'm trying to match parenthesis content using Kotlin.
I found that regex should be /\(([^)]+)\)/ but can't have it working in Kotlin.
val pattern = """/\(([^)]+)\)/""".toRegex(RegexOption.LITERAL)
val text = "aaaa (ferf ) veffef (frr) refef"
fun main() {
println(pattern.matches(text))
}
returns false.
You need to remove the initial and trailing slashes as you need to define the regex pattern using a string literal, and you need to only capture any chars other than parentheses inside parentheses and use findAll rather than matches to find all matches.
Use
val m = """\(([^()]*)\)""".toRegex()
val text = "aaaa (ferf ) veffef (frr) refef"
val results = m.findAll(text).map{it.groupValues[1]}.toList()
println(results)
See the Kotlin demo.
