Basic xml validator in javscript. This code may not valid for advance xml but basic xml.

function xmlValidator(xml){
    // var xml = "ToveJaniReminderDon't forget me this weekend!";
    while(xml.indexOf('<') != -1){
        var sub = xml.substring(xml.indexOf('<'), xml.indexOf('>')+1);
        var value = xml.substring(xml.indexOf('<')+1, xml.indexOf('>'));
        var endTag = '';
        if(xml.indexOf(endTag) != -1){
            // console.log('xml is valid');
            // break;
        }else{
            console.log('xml is in invalid');
            break;
        }
        xml = xml.replace(sub, '');
        xml = xml.replace(endTag, '');
        console.log(xml);
        console.log(sub+' '+value+' '+endTag);
    }
}
var xml = "ToveJaniReminderDon't forget me this weekend!";
xmlValidator(xml);
