If you use this ajax call:

var searchstring = "http://www.99restaurants.com/resources/proxy/KnowWhereProxy.php?state=CT";

$.ajax({

type: "GET",

url: searchstring,

dataType: "xml",

success: function(obj){ onLoadState(obj);}, error:function(msg,x,y){ alert(msg);}

});

and then try to parse the resulting XML like this:

function onLoadState(data) {

var jLocations = $(data).find("Location");

jLocations.each(function(intLocationIndex) {

// do something

});

}

jLocations has a length of 1. If you go var jLocations = data.getElementsByTagName("Location");, jLocations has a length of 16, returning all <Location> tags instead of just the first.
