Unable to parse data from XML file in parsing cloud using xmlreader in express app

My goal is to get the elements of the xml file that I have already saved in Parse Cloud for my express app. I started coding following the this link for the xmlreader and the Parse httpRequest guide to extract the parse file. I tested reading xml elements with xmlreader like this:

exports.xmlmodule = function(req, res) {
if (Parse.User.current()){
Parse.User.current().fetch().then(function(user){
var xmlreader = require('cloud/xmlreader');

var someXml =     '<dataset>'
        +         '<brands>'
        +            '<TheId>1</TheId>'
        +            '<ParentId></ParentId>'
        +            '<CategoryorProductName>Casuals</CategoryorProductName>'
        +         '</brands>'
        +         '<brands>'
        +            '<TheId>34</TheId>'
        +            '<ParentId>1</ParentId>'
        +            '<CategoryorProductName>Jeans</CategoryorProductName>'
        +         '</brands>'
        +    '</dataset>'


xmlreader.read(someXml, function (err, res){
if(err) return console.log(err);

// using the .count() and the .at() function, you can loop through nodes with the same         name:
for(var i = 0; i < res.dataset.brands.count(); i++){
    console.log( res.dataset.brands.TheId.at(i).text() );
    console.log( res.dataset.brands.ParentId.at(i).text() );
    console.log( res.dataset.brands.CategoryorProductName.at(i).text() );
}

console.log("");


});


});}
else{ res.render('login',{welcome: 'Please login to continue'});}
 };

      

        
        
        
      

    

and it worked. (Please ignore "user choice" which is not relevant here).

Then I tried to get the XML file from the parsing cloud using httprequest and it worked as well.

Now, when I combine both of these objects to get my target, I get an error:

Failed with: TypeError: Object [object Object] has no method 'charAt'

I used cloud function and here is my main.js

require ('cloud/app.js');
var xmlreader = require('cloud/xmlreader');
Parse.initialize("xxxxx", "xxxxx");

Parse.Cloud.define('myxmlfunction',function(req,res){
Parse.User.current().fetch().then(function(user){
var theid= user.get('StoreId');
var Stores= Parse.Object.extend('Stores');
var query= new Parse.Query(Stores);
query.equalTo('objectId', theid);
query.first().then(function(results){
var xmlfile= results.get('xmlfile');
Parse.Cloud.httpRequest({
url: xmlfile.url()
}).then(function(thefile){

var file = new Parse.File('thexml.xml', {
 base64: thefile.buffer.toString("base64")
});

xmlreader.read(file, function (err, res){
if(err) return console.log(err);

// using the .count() and the .at() function, you can loop through nodes with the same name:
 for(var i = 0; i < res.myrecord.brands.count(); i++){
     console.log( res.myrecord.brands.TheId.at(i).text() );
      console.log( res.myrecord.brands.ParentId.at(i).text() );
     console.log( res.myrecord.brands.CategoryorProductName.at(i).text() );
 }

 console.log("");

 });

 file.save().then(function() {
 res.success();
 }, function(error) {
 res.error(error);
 });
  });
  });
  });
  });

      

        
        
        
      

    

Note: The error displayed in log main.js 21:11 points to "xmlreader.read". Thus, it is obvious that the xml file received from the cloud cannot be viewed by the xmlreader.

My xml file:

 <?xml version="1.0" encoding="UTF-8"?>
 <myrecord>
    <brands>
       <TheId>a</TheId>
       <PId > g</PId>          
       <CategoryNameorProductName >Martin</CategoryNameorProductName>
    </brands>
    <brands>
       <TheId>b</TheId>
       <PId > c</PId>           
       <CategoryNameorProductName >Levis</CategoryNameorProductName>
    </brands> 
</myrecord>

      

        
        
        
      

    

Pay attention to the 'charAt' error. I started coding a month before and took a look at w3 xml tuts at noon today. Please help!
