not hard coded property fields of Ext.data.XmlReader ?

[FOONTIK]

I have xml

<ROWSET>
 <ROW>
  <TOTALROWS>4</TOTALROWS>
  <KEY>1</KEY>
  <ID type="int">1</ID>
  <CODE type="string">AS_ADMIN</CODE>
  <DESCRIPTION type="string">Администратор AS</DESCRIPTION>
 </ROW>
</ROWSET>

I want to get the variable xmlReader by url (or another), but not hard coded. How can I do that?

 function xmlFn(){
                var xmlReader = "{"+
                                "name: 'ID',"+
                                "type: 'int'"+
                                "}@ {"+
                                "name: 'CODE',"+
                                "type: 'string'"+
                                "}@ {"+
                                "name: 'DESCRIPTION',"+
                                "type: 'string'"+
                                "}";
                 var xmlReaderArr = xmlReader.split("@");
                 var xmlReaderArrOut = new Array();;
                 for (var key in xmlReaderArr) {
                    var val = xmlReaderArr [key];
                    xmlReaderArrOut[key] = Ext.util.JSON.decode(val);
                }
             return xmlReaderArrOut;

You want to have dynamic fields in your Store?

Yes, I want dynamic fields.
I need this part "fields: xmlFn()" as dynamic part.

Hi, everyone! Sorry I didn't give clearly explanation of my problem.

The Ext.grid.GridPanel component is great, but I've found only examples where
config-params "store" and "columns" have been hard-coded. I needed these configs as dynamic configs.

I'll give code. I hope It may help someone

Ext.Ajax.request({
                            url: 'AjaxReq',//this is a servlet, which return json-object
                            params: {
                                p_start: '1',
                                p_limit: '25',
                                p_filter: ''
                            },
                            scope: this,
                            disableCaching: true,
                            callback: function(options, success, response){
                                   
                                   response_Obj = response.responseText; 
                                   responseObj = Ext.util.JSON.decode(response_Obj);
                                   astore = responseObj.store
                                   acolumns = responseObj.columns

                         topPanel = new Ext.grid.GridPanel({
                                                    url: 'xxx.xml',
                                                    store: astore, 
                                                    columns: acolumns });

                         var win = new Ext.Window({ 
                                    ...

                                }); 

                                   win.show();
