I just check stackoverflow, and found this one,maybe it helps you.

var xml = 'Caleb';
var parser = new DOMParser();
var doc = parser.parseFromString(xml, 'text/xml');

Check for XML errors using JavaScript

if you are using chrome, then use google developer tools (press ctrl+shift+i), there you will find various options in the tab like ELEMENT(to see html code, styles of your document),CONSOLE(you will find errors and warning there), this is very useful, try and explore this one only.
