It is just a matter of parsing the result formxml property.

The only thing to be aware of, is if an attribute is added multiple times, the control's id is appended with a numeric suffix e.g. name1, name2 etc. The datafieldname attribute points to the attribute the control is referring to.

var data = getODataRecords(oDataUri);
if (data && data.value && data.value[0] && data.value[0].formxml) {
 var xml = jQuery(data.value[0].formxml);
 var controls = xml.find('control');
 jQuery.each(controls, function(index, control) {
     console.log(jQuery(control).attr('datafieldname'));
 });
}
