Answer 1

local-name(.) will give you the node name of the current node. If you used local-name(..) you would get the node name of the parent node.

xivalue('.','nvarchar(max)') will give you the content of the the current node.

@x.nodes('/Record/DELETED/*') gives you all nodes in /Record/Deleted .

So your query will give you a name/value list of all nodes in /Record/Deleted .
