IE9 refuses to process XML response

Question

This is a question in relation to this one.

In UPDATE II, I added a script based on Jamie\'s feedback.

UPDATE - tl;dr:

Answer 1

Perhaps give this a try? I use this with a google maps store locator. I notice $.parseXML actually does this internally, but its within a try/catch, and its saying your data is null (which is weird?)

      var xml;
     if (typeof data == "string") {
       xml = new ActiveXObject("Microsoft.XMLDOM");
       xml.async = false;
       xml.loadXML(data);
     } else {
       xml = data;
     }

From jQuery:

// Cross-browser xml parsing
parseXML: function( data ) {
    var xml, tmp;
    try {
        if ( window.DOMParser ) { // Standard
            tmp = new DOMParser();
            xml = tmp.parseFromString( data , "text/xml" );
        } else { // IE
            xml = new ActiveXObject( "Microsoft.XMLDOM" );
            xml.async = "false";
            xml.loadXML( data );
        }
    } catch( e ) {
        xml = undefined;
    }
    if ( !xml || !xml.documentElement || xml.getElementsByTagName( "parsererror" ).length ) {
        jQuery.error( "Invalid XML: " + data );
    }
    return xml;
},
