Retreiving Array Data From XML

I have XML data that is loaded into a mulitdimensional array.

I would like to call that information later in my actionscript but it seems that the array has not populated before I want to use it.

I am using the onload() method of the XML object.

I can trace the contents of the array directly after it is loaded with my loop, but later in the code a trace returns “undefined”. My array is globally scoped.

What can I do?
