[flexcoders] Re: e4x help
You're probably getting an e4x error on the first empty node (because Attribute
doesn't exist there).
Try to avoid this issue by using the "hasOwnAttribute" function to make sure
that "Attribute" actually exists in that node. This probably isn't it, but
it's close:
xmlRoot..(hasOwnAttribute("Attribute"))
I'm not sure the above will work because we're not returning a specific level,
but hopefully you get the idea. Use the following URL for a great explanation
of Advanced E4X:

Hope that helps...

RE: [flexcoders] Re: E4X Help
You also need to change = to == in your E4X filter. A working example is below.

Tangent,
Remove the {} from around selected :
var counties:XMLList = _myXml.state.(@label=selected).county;
