App broke over night (XML not parsing)

Question

I had a nicely working app that used an external xml file as
its data source. I woke up early this morning excited to be able to
move on and add simple functionality to my app. But it when I
reopened and compiled it, it had stopped parsing the xml. Thinking
I might have typed in something by mistake, I went to a back up
version I knew worked (I had saved it with a _working prefix). That
one no longer parsed either.
After a couple of hours of troubleshooting, I thought let me
try a simple HTTPService example. I found the below code as an
example to see if it would work. And it doesn't work either.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="vertical"
initialize="myService.send()">
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import mx.rpc.events.ResultEvent;
[Bindable]
private var myData:ArrayCollection;
private function resultHandler(event:ResultEvent):void {
myData = event.result.titles.title;
]]>
</mx:Script>
<mx:HTTPService id="myService"
url="data/videoTitles.xml"
result="resultHandler(event)"/>
<mx:DataGrid dataProvider="{myData}"/>
</mx:Application>
Here is my xml file (in a data subdirectory)
<?xml version="1.0"?><?xml version="1.0"?>

And this doesn't work either. Mind you, these were working
before. I've restarted my machine, turned it off and turned it back
on. I'm using a mac osx (latest operating system as this is a new
intel macbook). I'm using the flex 2 sdk free downloaded one week
ago.
any ideas?

Answer 1

Thanks. I've stripped everything down to the simplest of
examples - which does not work for me.
my xml file (in the same directory as my mxml file)
<?xml version="1.0" encoding="UTF-8"?>
<title>test #3</title>
my mxml file:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
creationComplete="simple.send()">
<mx:HTTPService id="simple" url="simple.xml" />
<mx:Text width="100" id="question" htmlText =
"{simple.lastResult.title}"/>
</mx:Application>
It compiles okay. The command I'm using to compile is:
steve-odoms-computer:~ steveodom$ flex/bin/mxmlc
Desktop/hellomxml.mxmlLoading configuration file
/Users/steveodom/flex/frameworks/flex-config.xml
/Users/steveodom/Desktop/hellomxml.swf (183423 bytes)
steve-odoms-computer:~ steveodom$
Both files are on my desktop. Nothing shows up.
Mind you, I had a more complicated solution working before
this morning. I woke up, changed nothing, and started having this
problem.
thanks,
Steve
