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

Answer 1

let input: string = "ab<br/><br/>cd<br/>efg<br/><br/><br/>hijk<br/><br/>";

// Regex to match one or more consecutive <br/> tags
let pattern: RegExp = /(<br\s*\/?>\s*)+/gi;

// Replace with a single <br/>
let output: string = input.replace(pattern, "<br/>");

console.log(output);

 
 
/*
run:
 
"ab<br/>cd<br/>efg<br/>hijk<br/>" 
 
*/
