How to convert multiple <br/> tags to a single <br/> tag using RegEx in Swift

Answer 1

import Foundation

var input = "ab<br/><br/>cd<br/>efg<br/><br/><br/>hijk<br/><br/>"

// Define regex pattern and use NSRegularExpression for replacement
let pattern = "(<br\\s*/?>\\s*)+"
let regex = try! NSRegularExpression(pattern: pattern, options: [])

let range = NSRange(location: 0, length: input.utf16.count)
input = regex.stringByReplacingMatches(in: input, options: [], range: range, withTemplate: "<br/>")

print(input)



/*
run:

ab<br/>cd<br/>efg<br/>hijk<br/>

*/
