How to get all nodes from XmlReader?

[chernomorez]

I have a page which is accessing a service returning the XML, and I want to iterate through all the XML nodes without calling them individually in config of XmlReader.

For example, if my XML record is this:

<ds>
  <firstName>Joe</firstName>
  <lastName>Smith</lastName>
  <userID>123</userID>
  <address>123 A Street</address>
  ...
</ds>...

and this is my data reader creation

var myReader = new Ext.data.XmlReader({
		        totalRecords:'TotalCount',
               record: 'ds',
               id: 'userID'
           }, [
               'userID','firstName', 'lastName'
    ]));

How can I avoid listing all the properties, and get all of them at once?

Thanks

There's a thread in Examples (maybe moved to User Extensions) that shows how to dynamically build the colModel on the fly. It may be JSON-based, but you should be able to adapt it to XML.
