Xml and xpath

Xml and xpath

I am trying to load an xml, and then to query it using xpath.

i've tried this:

$.ajax({
type: "GET",
url: "Menu.xml",
dataType: "xml",
success:
function(xml)
{
$(xml).find('/Root/Item').each(...);

}
}

It didnt work, i've also tried this:

$('/Root/Item',xml); and it also didn't work.

How can i query only for item nodes that are under root?

I know that i can do this: $(xml).find('item'); - But this returns me all item nodes regradless if it is the first child of root or not.

PLz help me
