I'm trying to create an HTML table using javascript from a String that I will get from a database. the data is a wiki table like the example I will leave below:

||Information Communicated||who||when||Complete|||aa|aa|aa|aa|

I've tried using this regex expression: [^|]*\||(\w+)\||

but it's selecting all pipes. I want to get the double pipe with the string between the first || and last || which means in this case

||Information Communicated||who||when||Complete||

I don't know what is missing but please help me

... _"I want to get the string between the first || and last ||"_ ... thus, the OP wants to be `'Information Communicated||who||when||Complete|'` the matching/captured result? – Peter Seliger Jun 09 '22 at 12:40
`\|\|(?.+?)\|\|` will match only text between double pipes – Diego D Jun 09 '22 at 12:41
Sorry i meant the double pipe with inbetween string -> ` ||Information Communicated||who||when||Complete||` – Nessrine Hafi Jun 09 '22 at 12:42

It should be `\|\|(.*)\|\|` or `\|\|.*\|\|`. See [demo](https://regex101.com/r/VS1mNa/2). – Wiktor Stribiżew Jun 09 '22 at 12:42

Or `\|\|(.*[^|])\|\|`, see [this demo](https://regex101.com/r/VS1mNa/3). – Wiktor Stribiżew Jun 09 '22 at 12:52
