Add node to XML actionscript

Add node to XML actionscript

The code below produces an XML menu in the form:

Themenu
       ITEM1
            ITEM1SUBITEM1
            ITEM1SUBITEM2
            ITEM1SUBITEM3

       ITEM2
            ITEM2SUBITEM1
            ITEM2SUBITEM2
            ITEM2SUBITEM3

How do I change the code to add another node level to produce a menu in the form:

Themenu
       ITEM1
            ITEM1SUBITEM1
            ITEM1SUBITEM2
            ITEM1SUBITEM3
                         ITEM1SUBITEM3SUBSUBITEM1
                         ITEM1SUBITEM3SUBSUBITEM2

       ITEM2
            ITEM2SUBITEM1
                         ITEM2SUBITEM1SUBSUBITEM1
                         ITEM2SUBITEM1SUBSUBITEM2
            ITEM2SUBITEM2
            ITEM2SUBITEM3

Thank you.
