regular expression matching - javascript

Question

I have a string of html contained in between [marquee][/marquee] tags in the string like so:

var s = '[marquee]<p>some html here 1</p>[/marquee][marquee]<p>some html here again 2</p>[/marquee]';

what I would like to do is match each one of these marquees to create an array with each marquee as an array element.

What I've tried so far is:

var marqueeArray = s.trim().match(/\[marquee\][\s\S]*\[\/marquee\]/g);

but all i get back is and array with the length of 1. both marquees end up being included as one string like this:

["[marquee]<p>some html here 1</p>[/marquee][marquee]<p>some html here again 2</p>[/marquee]"]

what i would like is this:

["[marquee]<p>some html here 1</p>[/marquee]", "[marquee]<p>some html here again 2</p>[/marquee]"]

eventually i will need to remove the brackets ([marquee] and [/marquee]) from each element and replace with and join one big string for use in the application. any point in the right direction on that would be great as well.

You can use `s = s.split(/\[\/?marquee\]/).join("");` – Titus May 03 '17 at 14:26 — Titus, May 03 '17 at 14:26

You only have to use ? quantifier to make your search lazy.

Add ? as mentioned \[marquee\][\s\S]*?\[\/marquee\]

The following will match all marquee tags and the content between them.

s.match(/(\[marquee\].*?\[\/marquee\])/g);

If you want to capture the content between the marquee tags you can use the following:

var pattern = /\[marquee\](.*?)\[\/marquee\]/g;
var match = pattern.exec(s);
while(match != null){
  console.log(match[1]); // Prints out content between tags
  match = pattern.exec(s);
}
