set:difference() returns the difference between two node-sets. In other words, it returns a node-set whose nodes are in one node-set but not in the other.

The template version of set:difference applies templates to these nodes in set:difference mode, copying the nodes so that a result tree fragment consisting of the nodes is returned.

Syntax

set:difference(nodeSet1, nodeSet2)

Parameters

• nodeSet1

  • : The node-set from which to subtract nodes.

• nodeSet2

  • : The set of nodes to subtract from nodeSet1.

Returns

A node-set containing the nodes that are in nodeSet1 but not in nodeSet2.
