Replace "Environment.NewLine" inside a with Regex

Question

I was asking myself if it possible to replace all the Environment.NewLine in a specific div with Regex? I tried some regex by myself but I didn't succeed in it. By the way, I know it's not the right way to parse HTML with Regex.

This is what I had so far:

Regex.Replace(text, @"(?<=<div class=""text"">.*?)" + Environment.NewLine + "(?=.*?</div>)", "<br/>");

Thanks!

  @"(?<=<div class=""text"">.*?)((?<!\n)\r\n|\n\r|\r|\n)(?=.*?</div>)", 
  "<br>");
