Load XML file from different location?

Question

Hi All,
I've been going through an exercise by Karl Matthews to load XML data into an AIR App:
http://www.adobe.com/devnet/air/flex/articles/xml_viewer_on_air.html
but I would like to change where the XML file used in the project is retrieved from.
Currently the XML file is loaded from here:
<!-- Set up the HTTP service from where we get the source XML data -->
<mx:HTTPService id="srcData" url="
assets/UserGuide.xml" result="loadModelData(event)"
/>
but I would like to load the XML file from one of these locations instead:
File.userDirectory:
File.documentsDirectory:
Can someone please show me how I should change the above code to accomplish this, as my efforts to date have not been successful :-(
I am using Flex Builder 3 and Air 1.5.
Thanks heaps!
Tim

Hi Bhasker,
Thank you for replying.
I am not very good at all this coding, but I am assuming I should now be doing entering the following:
=======================
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication 
xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"width="
800" height="660"xmlns:comp="
*" xmlns:fmtComp="fmtComps.*"creationComplete="srcData.send()"
paddingLeft="
0" paddingRight="0" paddingTop="0" paddingBottom="0">
<mx:Script>
<![CDATA[
import mx.utils.ObjectProxy; 
import mx.rpc.events.ResultEvent; 
Bindable] 
private var userManualObj:ObjectProxy; 
private function loadModelData(event:ResultEvent):void
userManualObj=event.result.UserManual;
private function readXMLContent(xmlFile:File,objContentView:Object):Array{
var reportDir:File = File.userDirectory.resolvePath("assets"); 
var xmlFile:File; 
var fileStream:FileStream = new FileStream(); xmlFile = reportDir.resolvePath(
"UserGuide.xml"); 
if(xmlFile.exists && xmlFile.size > 0)// Checking if the impressions.xml file already exists and the file is not empty
var stream:FileStream = new FileStream(); 
var xml:XML = new XML();stream.open(xmlFile, FileMode.READ);
xml = XML(stream.readUTFBytes(stream.bytesAvailable));
stream.close();
]]>
</mx:Script>
<!-- Set up the HTTP service from where we get the source XML data<mx:HTTPService id="srcData"
url="assets/UserGuide.xml"
result="loadModelData(event)"/> -->
<mx:VBox width="100%" horizontalAlign="left" height="100%" paddingBottom="
0" paddingLeft="0" paddingRight="0" paddingTop="0">
<mx:TabNavigator width="100%" height="100%"paddingBottom="
0" paddingLeft="0" paddingRight="0" paddingTop="0">
<mx:Repeater id="modelsRep" dataProvider="{userManualObj.Product.Model}">
<mx:VBox label="{modelsRep.currentItem.Name}" width="100%" height="100%">
<comp:ModelDesc model="{modelsRep.currentItem}"/>  
</mx:VBox>
</mx:Repeater>
<mx:VBox label="Troubleshooting" width="100%" height="100%"paddingBottom="
0" paddingLeft="0" paddingRight="0" paddingTop="0">
<comp:Troubleshooting issues="{userManualObj.Product.Troubleshooting.Issue}" />
</mx:VBox>
</mx:TabNavigator>
</mx:VBox></mx:WindowedApplication>
=======================
and create and "assets" folder in my user directory placing the XML file in there?
However when I do all that, I get this error when I try to compile:
  Encountered errors or warnings while building project main.mxml.
    main.mxml: Function does not return a value.
Any thoughts?
Many thanks,
Tim
