Description

With a SetExpr you can select the union or intersection of node sets. A union set is constructed by using the operator | and contains all nodes that are in any one of the node sets. An intersection is constructed by using the operator intersect and contains only those nodes that are in all nodes.

Compatibility

It corresponds to the expression UnionExpr defined in XPath, Section 3.3, Rule 18. However, X-Query adds the intersect operator which is not present in XPath.
