i want to get the whole text from the first div like this

<div dir=\"ltr\">First div <div>is use </div><div>for test</div></div>
First div is use for test

Maybe just parse your string as valid HTML input:

var parser = new DOMParser();
var htmlDoc = parser.parseFromString('<div dir=\"ltr\">First div <div>is use </div><div>for test</div></div>', 'text/html');
var htmlCollection = Array.from(htmlDoc.querySelector('div').innerText)
console.log(htmlCollection.join(""));

here is a RegEx that will match your needs:

(!?(<.*?>)|[^<] )\s*

Thats how you get the Text between all tags in your email text. It even works for all other tags! (so its ignoring everything between < >)
