Jason,
Yes, I see. Thanks again.
A couple of people have asked to see the finished product. I'll upload it to
my web site along with the FLA, XML and AS files for download when I'm
finished.

Bryan,
If you look at the last e-mail I posted before this one (also included
un-trimmed in this e-mail), you'll see I answered that already (and your
question about not getting it to display). In short, yes. Check below or
in my prior e-mail for the example.
Glad you got it working. I don't know why Macromedia didn't/doesn't
implement an object model like this for XML already - the XML objects
provided are so difficult to navigate through for some people - like me. I
mean, its workable, but start doing any thing complicated and it gets messy.
Anyhoo - happy you were able to make use of that prototype - wish I had
written it myself, but I can't take credit for it.

:::>In other words, don't try and display the XML before its ready.
