How to check if XMLLIST is empty in Flex

October 20, 2021By Simo Flex

If I have an XMLList object in Flex, what is the correct way to check if the list is empty? Should I just compare the results of myList.length()>? 0, myList.toString()! = “” Or try another method?

I will choose the simple myList.length()> 0 method.

You can see an example of the length() function in the ECMAScript for XML (E4X) specification (page 104), Actionscript implements this function.
