Unfortunately not. This gets me to the point at which I am already (and what a struggle THAT was!) but I can already access nodes from the root level. Now, however, I need to access named sub-nodes of a particular node (in my example, ASIN of /ItemLookupResponse/Items/Item). It's not really helpful to access it from root (/ItemLookupResponse/Items/Item/ASIN) because there may be several Item nodes.
