How to check if an XMLList is empty in Flex

Question
If I have an XMLList object in Flex, what is the proper way to check to see if the list is empty? Should I just compare the result of myList.length() > 0
, myList.toString() != ""
or try another method altogether?
Solution
I would go with the simple myList.length() > 0
method.
You can see an example of the length()
function in the ECMAScript for XML (E4X) specification (page 104), which Actionscript implements.
