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.

:::>you need to do to
:::>display the text - like have it in frame 2 or something.

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