by gavin, 6489 days agosure. simple really. i'm thinking of the way they do it in ruple or in the xmlspaces paper or in xset. basically you use an "example" of what you're looking for, say you queried with < entry>< book>< /entry>. you'll received all entry docs that contain book as a child to entry. that's a simple xpath as well, it's when you begin constructing deeper queries that this method really shines. xset, in particular, has a storage model that assumes this type of query.
