Regex: select only urls from an unusual string

In my old database there are fields of such content:

a:2:{s:6:"item-0";a:1:{s:17:"siteurl";s:25:"https://www.urlsite.com/";}s:6:"item-1";a:1:{s:17:"siteurl";s:29:"https://urlsite2.org/";};a:1:{s:17:"siteurl";s:29:"https://urlsite3.com/";}}

I need to select only the url from this, so that something like this happens:

https://www.urlsite.com/,https://urlsite2.org/,https://urlsite3.com/

At the moment I use this construction:

.*?(http.*?(\.org|\.com))

However, I get this result:

https://www.urlsite.com,https://urlsite2.org,https://urlsite3.com,/";}}

It is not possible to select the end of the line after the last url and it gets into the result.

,/";}}

>Solution :

A JavaScript implementation:

const text =
  'a:2:{s:6:"item-0";a:1:{s:17:"siteurl";s:25:"https://www.urlsite.com/";}s:6:"item-1";a:1:{s:17:"siteurl";s:29:"https://urlsite2.org/";};a:1:{s:17:"siteurl";s:29:"https://urlsite3.com/";}}';

const result = text.match(/http.*?(.com|.org)\//gm);

console.log(result.join(','));

Results in:

https://www.urlsite.com/,https://urlsite2.org/,https://urlsite3.com/
