If user is entering normal string, I need not to convert it to Xml format.. If I get Html data, then I have to convert into Xml. How can I check that without using Regex?

It is hard to be 100% sure if a user enters HTML or plain text, especially using regexp. A better option is probably to first ask the user what he/she will enter, then handle input accordingly. – Stefan Mar 18 '19 at 07:00

User will enter a normal string only, but the text area will convert that into Html. – Sangeet Mar 18 '19 at 07:03

Html and Xml always Starts with < Tag. the simplest without regex way of checking if it not Start with < then it is normal String. Otherwise If it start with < then it may be normal String or HTML too.
And Html contains <html> Tag.

Try the following function
function isHTML(str) {
var a = document.createElement('div');
a.innerHTML = str;
for (var c = a.childNodes, i = c.length; i--; ) {
if (c[i].nodeType == 1) return true;
}
return false;
}
