How to find XML node by attribute, compare it to known string, and if matching, get s

Hello,

I am trying to figure out how to find an XML node by way of one of its attributes, compare that attribute to a known string, and once I find the match, get the sibling attribute in that same node.

Here is what I have so far.

Code:

---

var glossaryObj = {};

$.get(pURL, function(xmlFile)
{
        $.ajax({
                type: "GET",
                url: pURL,
                dataType: "text",
                success: parseGlossXML
                });
});


function parseGlossXML(xml)
{
        glossaryObj = xml
        $(glossaryObj).find('term').each(function(){
                alert($(glossaryObj).filter(":first").attr('def'));
        });
}

This is a sample of the XML file, it is not the complete file.

Code:

---

<item term="AAA" def="Not the American Automobile Association" rollover="Anti-aircraft Artillery" />


<item term="ABCCC" def="Airborne Battlefield Command and Control Center" />


<item term="ABP" def="Air Battle Plan" />


<item term="AC" def="Active Component" />
