Something wrong with my XML? - extjs

Question

i'm parsing an xml with my extjs but it returns only one of the five components.
only the first one of the five components.
Ext.regModel('Card', {
fields: ['investor']
});
var store = new Ext.data.Store({
model: 'Card',
proxy: {
type: 'ajax',
url: 'xmlformat.xml',
reader: {
type: 'xml',
record: 'investors'
}
},
listeners: {
single: true,
datachanged: function(){
Ext.getBody().unmask();
var items = [];
store.each(function(rec){
alert(rec.get('investor'));
});
and my xml file is:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<investors>
<investor>Active</investor>

Answer 2

You need to visit the sencha.com tutorial on how to use XML with a grid.
XML Grid Sample
You should take not of how to properly structure your XML so that it can be consumed by a data store.

Answer 3

The Ext XML grid needs to be configured to look for the repeating elements to map to each record in your store/grid. You had it configured for investors, of which there is only 1. Then you mapped a field for investor and it is just grabbing the first one that it encounters for the "column" of that "row".
The repeating element for your "rows" in the grid should be investor, not investors.
Change: record: 'investors'
to: record: 'investor'
