R – DOJO XHRPOST DATAGRID

I am trying to load the following xml data rendered from a JSP page and display the name, city , state and hide zip. How do I do it in dojo?
I have tried some code , but have not made any big progress. The code works for JSON data.

XML DATA rendered from a JSP/Servlet

customers/
/customer
/name/JOHN DOE/name/
/city/SFO/city/
/state/CA/state/
/zip/94087/zip/
/customer
/customer
/name/SUSAN SMITH/name/
/city/CHICAGO/city/
/state/IL/state/
/zip/61706/zip/
/customer/
/customers/

JAVASCRIPT CODE

// make request to the customers web service
function loadTable(page){

var targetURL = "test.jsp"; 
dojo.xhrGet({
    url: targetURL,
    handleAs: "xml",
    mimetype: "text/xml",
    load: handleResponse,
    error: handleError
});

}

var view1 = {
cells: [
[
{name: 'Company', field: "name"},
{name: 'City', field: "city"},
{name: 'State',field: "state"},
{name: 'Zip',field: "zip"}
]
]
};
// a grid layout is an array of views.
var layout = [ view1 ];
// the model will contain the data to be displayed in the view
model = new dojox.grid.data.Objects([{key: "name"}, {key: "city"},{key: "state"},{key: "zip"}], null);

// Process the response from the customers web service
function handleResponse(data, ioArgs){
dojo.require("dojox.grid.DataGrid");
dojo.require("dojox.xml.DomParser");
HOW do I load data into the model here?
//alert(data);
var jsonStore = dojox.xml.DomParser.parse(data);

// set the model object with the returned customers list to be displayed in grid 
model.setData(jsonStore);
