Finding strings with 3 letters and 3 numbers(ID's) in large text Javascript

Question

I need to locate all strings in a large text document which includes 3 letters and 3 numbers such as: FPV003

But there are hundreds of different strings of such type in-between regular text,

I've tried Regex, but cant get it to work,

How do I locate these 6 charactered strings consisting of 3 random numbers and 3 random letters.

`I've tried Regex,` what have you tried? `/[A-Z]{3}\d{3}/mg` ? — Jaromanda X, Oct 16 '17 at 10:11

A regex should be fine here :

var patt = /[A-Z]{3}[0-9]{3}/g;
var str = "test test AZE123 test test ZER456";

console.log(str.replace(patt, 'it works'));

What if it returns `AZE123` from `0000000AZE123_45` and OP does not expect that? – Wiktor Stribiżew Oct 16 '17 at 10:29
Thank you so much :) So all the strings I need to find comes in order of NUMBERNUMBERNUMBERLETTERLETTERLETTER – Frederik Peter Volkers Oct 16 '17 at 10:32

Thank you so much :) So all the strings I need to find comes in order of LETTERLETTERLETTERNUMBERNUMBERNUMBER aaa111 So I think it will find everything with this code;

var content = document.getElementById('indhold').innerText;
var UID = content.match(/[a-zA-Z]{3}[0-9]{3}/g)
