Base Claim:
1. A method comprising: receiving a first query that conforms to a first XML query language; determining that an operator included in the first query requires one or more node references, to one or more nodes, as operands of the operator instead of a value of any of the one or more nodes; wherein the operator included in the first query is one of a node comparison operator or an operator that requires context node traversal; and in response to determining that the operator included in the first query requires one or more node references as operands of the operator, generating, based on the first query, a second query (a) that conforms to a second XML query language that is different than the first XML query language and (b) that includes a particular operator not included in the first query; wherein execution of the particular operator included in the second query causes a reference, to a node in an XML document, to be returned instead of a value of the node; wherein the steps are performed by one or more computing devices.
