Prototype Ajax.Request: how can i return responseXML to main function

[alex.david]

Hi,

in tutorials you find this code sample:

var myMap;
....
var url = "my_xml.xml";
var myAjax = new Ajax.Request(
url,
{
method: 'get',
onComplete: showResponse
});

// here i need something like:
// response = someObject.responseXML;
// so i can do this:
// myMap.createSomeMarkersWith(response);
....

function showResponse(request){
doSomethingwith(request.responseXML);
}

How can I use the responseXML in the "calling function"?
Reason is, I don't want to pass all the vars through the functions (and
I don't know how, anyway).
myAjax doesn't seem to have a responseXML or anything helpful at all.

Thanks in advance
Alex
