[jQuery] Simple Ajax question

[Thomas]

Hi!
I have a basic question with jQueryed ajax. How can I reach elements
by tag name ?

I have this js:
$.ajax({
        url:    "some.xml",
        type:   "POST",
        dataType: ($.browser.msie) ? "text" : "xml",
        processData: false,
        complete: function(data) {
        var xml;
        if (typeof data == "string") {
                        xml = new ActiveXObject("Microsoft.XMLDOM");
                        xml.async = false;
                        xml.loadXML(data);
                } else {
                        xml = data;
                }
                alert(xml.responseText);
        }
});

and I have this "some.xml":
<?xml version="1.0" encoding="UTF-8"?>
<root>
        <item>apple</item>
        <item>banana</item>
</root>


So the problem is, that I don't know how reach "item"s. The old method
(firstChild.text) doesn't works, of course, or does it ?
