Reminder: The best comparison for a database query, in the XML world, is XQuery -- a synthesis of XPath and XSLT. It's structural rather than relational, but many of the concepts are the same and XQuery is probably the best spec to study if you want to see how they map into each other.

(The XSLT 2.0 spec, by the way, is literally generated from the same
source files as the XQuery spec; it drops a few features, adds a few features, and uses slightly different syntax but the underlying semantics are intended to be identical.)
