[jQuery] XML selectors not working in > 1.1.2 ?

[jQuery] XML selectors not working in > 1.1.2 ?


Using the Ext JS DateField which exposes a bug with 1.1.2 that
prevents navigation beyond a month. They suggest using a release >
1.1.2 as the bug has been resolved.
Problem is the following code (simplified for this example) no longer
works:
function xmlFromStr(text){
    if (typeof DOMParser != "undefined") {
        return (new DOMParser()).parseFromString(text,"application/xml");
    } else if (typeof ActiveXObject != "undefined") {
        var doc = new ActiveXObject("Microsoft.XMLDOM");
        doc.loadXML(text);
        return doc;
    } else {
        var url = "data:text/xml;charset=utf-8," +
encodeURIComponent(text);
        var request = new XMLHttpRequest();
        request.open("GET", url, false);
        request.send(null);
        return request.responseXML;
    }
}
theXMLObj = xmlFromStr("<data><el>text</el></data>");
alert($("el",theXMLObj).size());
Am I missing something or is this a legit bug?
