Simply put, I'm trying to replace certain tags with BBcode. What I have at the moment seems to grab the first <b> skips the following closing tag </b> and instead matches with the next one, leaving a closing tag inbetween them and keeping another one open.
I'm not sure how to fix the expression to capture the two groups of tags separately.
const test = `
<zxlarge><b>Title and stuff
- Yo</b></zxlarge>

<zlarge><b>Preface.</b></zlarge>
<i>What if making excellent menu systems was as easy as a single command, and you also had access to the code?</i>
`;
let result = test.replace(/<b>([\s\S]*)<\/b>/gi, '[b]$1[/b]');
console.log(result);By default regexes are greedy, they eat as much as possible as long as they get a match (they will prefer one big match, more than many small matches).
To make a part of the regex ungreedy, you'll have to replace your * by a *?.
