How to check if an XMLList is empty in Flex

actionscript-3, apache-flex, e4x, xml

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.

Problem

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?
