How do I navigate to Item structure elements and attributes

Summary:

I have an Item that has a 'StructureX'. I want to navigate to the connected child Items and access the child items and its specific 'Additional Attibutes' stored at the structure level.

changed([Structure].[Structure Attributes].[Structure Name]=="StructureX")
