I am currently getting response error in html format. It is of type string.

"<!DOCTYPE html>\r\n
<html>
  <head>
    <title>Data already exists</title>
  </head>
</html>"

I wanted to retrieve the content inside the <title>, for above instance “Data already exists”. Can anybody suggest a appropriate regular expression to capture that text.

Please any help is appreciated!

    First, you can do it without regex, by creating a dummy element to inject the HTML:

    var s = "your_html_string";
var dummy = document.createElement("div");
dummy.innerHTML = s;
var title = dummy.getElementsByTagName("title")[0].innerText;

    But if you really insist on using regex:

    var s = "your_html_string";
var title = s.match(/<title>([^<]+)<\/title>/)[1];

    Here’s a DEMO illustrating both approaches.
