AS3 returns a string of XML nodes as null....

Question

I am working on a project that calls and searches an XML sheet that looks like this:
    <Searchtext Wordlookup="john smith">
        <location>$1</location>
        <Name>john smith</Name>
    </Searchtext>
and it continues like this for about 100+ people.
Now, my flash takes this data and allows the user to either click on a textbox prefilled with a name (whose e.target.data.text is matched up to the xml using @Wordlookup) or type in the name of the person (again matching the textbox's content to @Wordlookup) which results in the location of that person lighting up (MC's are named the same as the location node for each). This end works perfectly fine using this code:
  var result:String = xmldata.Searchtext.(@Wordlookup == inputTxt.text.toLowerCase()).location.toString(); 
Now I want to do the opposite; click on a location, and the code will match up that movieclip's name to a location node in my xm - light up that location, and output the person's name in the textbox. Only problem in that Flash apparently thinks a node in my xml is now a variable that is undefined (it should return as the name that is related to the location in my xml). I have looked high and low for a solution, but I just can't seem to solve it (it is probably simple, and I'll facepalm myself) The error inducing code is this:
  var resultz:String = xmldata.Searchtext.(location.text() == e.target.name).Name.toString();
And the error produced is this: ReferenceError: Error #1065: Variable location is not defined.
Not sure exactly why this is happening, thank you in advance for any help!

So my as3: (I gave you this chunk in case I've just completely missed something here)
                              loader = new URLLoader();
                              loadXML();
                    private function loadXML():void
                              loader.load(new URLRequest("data.xml"));
                              loader.addEventListener(Event.COMPLETE, onXMLLoaded)
                              trace("loaded");
                    private function onXMLLoaded(e:Event):void
                              xmldata = new XML(loader.data);
                              var itemXMLList:XMLList = XMLList(xmldata.Searchtext..location);
            var count:int = itemXMLList.length();
            trace(count);
                              trace(xmldata.Searchtext.location[25].text().toString(),xmldata.Searchtext.location[25].text.length().toString());
                       trace(xmldata.Searchtext.location[0].text().toString(),          xmldata.Searchtext.location[0].text.length().toString());
        private function LocationClick(e:Event):void
//         var resultz:String = xmldata.Searchtext.(location.text().toString() == e.target.name).Name.toString();
//         inputTxt.text=resultz;
           trace(e.target.name, e.target.name.length);
           inputTxt.text=e.target.name;          
My output using this:
loaded
78
$1 0
$2 0
$1 2
$2 2
