[Flashcoders] empty XML Attributes..

[Glen Pike]

Hi,

   I am having problems parsing some XML config files and testing for 
empty attributes.  There is an example xml below.
  
   Problem is that I am asking for the following:

   _co...@instance
  
   Which is returning a value, but I am not sure what type of value.  
Should this return null, or an empty string or something??

       var _conf:XML =    <screen name="Library" 
swf="LibraryScreenTest.swf" 
symbol="com.robothespian.screen.LibraryScreen" config="library.xml" />
  

Glen
