ActionScript 3.0 :: How To Pass Variables Between Packages

I am working a xml-loader class. My aim is to split xml-loading process to two different packages. 1. XMLLoader.as load data from external xml files. 2. XMLProcessor.as stores the xml-data to the array for the further use. 3. Both packages are controlled by DocumentClass.as. 4. ContentMOV.fla is completely without code.Tree hierarchy is ollowing: quest01/website/classdocs 1. ContentMOV.fla is in quest01 folder, 2. DocumentClass.as is in website folder, and3. XMLLoader.as and XMLProcessor.as are both in classdocs folder.The DocumentClass path in fla-file is website.DocumentClass. "Browse to Path" is set from Edit/Preferences/ Language: ActionScript 3.0 Settings... to one folder before quest01 folder.

However, I am completely out of idea, how I can pass XMLDocument to the DocumentClass or XMLProcessor package. For example, I have tried following in DocumentClass: var XMLDocToEditmlDocument = new xmlDocument(); LDocToEdit.xmlDocument();However, these lines cause two errors in compiler: 1046: Type was not found or was not a compile-time constant: xmlDocument. 1180: Call to a possibly undefined method xmlDocument. DocumentClass.as is now as follows:

Code:
package website {
import flash.display.Sprite;
