How to trace XML child in AS3 using the forEach loop?

I am trying to use the forEach Loop action to trace every Artist name in the output panel and am having a difficult time with the syntax. I am not getting any results (not even errors). I have the XML loaded and am able to trace a direct path to a child, but want it to be dynamic.

Here is my XML:

<library>
  <artist title="DreamTheater">
        <album title="A Dramatic Turn of Events" art="images/bg.jpg" soundtrack="audio/soundtrack.mp3">
            <tracks>      
                <track>On the Backs of Angels</track>
            </tracks>
        </album>
    </artist>

    <artist title="Rush">
        <album title="2112" art="">
            <tracks>      
                <track>Something For Nothing</track>
            </tracks>
        </album>
    </artist>   
</library>

and here is my AS3 function:

function artistListLoad():void{ 
    for each (var artist:XML in mainXML) { 
    trace(artist);                        
    } 
}

I am a beginner with the forEach loop and don't understand it yet so comments are appreciated!

Firstly, you need to user mainXML.artist if you want to iterate over the artist nodes within the XML:

for each(var artist:XML in mainXML.artist)

From there, you can access children, attributes and attributes of children within each artist block in the XML. Quick sample:

function artistListLoad():void
{ 
    for each(var artist:XML in mainXML.artist)
    {
        trace(artist.@title);
        trace(artist.album.@title);
    } 
}

Note that the @ symbol is used to select attributes of the node, whereas without it, you will select children within the node.
