[flexcoders] Built-in way to determine the number of XML elements

[Daniel Thompson]

I'm trying to see if a response from the server is empty. So, in one case I
end up with:

<root>
  <matches/>
</root>

And in the other, I get:

<root>
  <matches>
    <match ... />
  </matches>
</root>

Using this fancy E4X, how do I test for the different conditions? I always
seem to be getting back an XMLList, be it empty or not. I can't imagine I
have to iterate this and check that it's zero at the end, but length doesn't
do it, and I can't check for null because I'm always getting an XMLList.

Thanks,
