Functions: Difference, Distinct, HasSameNode, Intersection, Leading, Trailing |  |  |  | Fields: EXSL_SETS_NS, ExtElements, ExtFunctions, ExtNamespaces

## Functions

Difference(context, nodes1, nodes2)
The set:difference function returns the difference between two node sets - those nodes that are in the node set passed as the first argument that are not in the node set passed as the second argument.
Distinct(context, nodeset)
The set:distinct function returns a subset of the nodes contained in the node-set NS passed as the first argument. Specifically, it selects a node N if there is no node in NS that has the same string value as N, and that precedes N in document order.
HasSameNode(context, ns1, ns2)
The set:has-same-node function returns true if the node set passed as the first argument shares any nodes with the node set passed as the second argument. If there are no nodes that are in both node sets, then it returns false.
Intersection(context, ns1, ns2)
The set:intersection function returns a node set comprising the nodes that are within both the node sets passed as arguments to it.
Leading(context, ns1, ns2)
The set:leading function returns the nodes in the node set passed as the first argument that precede, in document order, the first node in the node set passed as the second argument. If the first node in the second node set is not contained in the first node set, then an empty node set is returned. If the second node set is empty, then the first node set is returned.
Trailing(context, ns1, ns2)
The set:trailing function returns the nodes in the node set passed as the first argument that follow, in document order, the first node in the node set passed as the second argument. If the first node in the second node set is not contained in the first node set, then an empty node set is returned. If the second node set is empty, then the first node set is returned.
