EXSLT - set:intersection - Implementer Page

Version: 1
Status: stable
User Page: index.html
XML Definition: set.intersection.xml
Function Package: set.intersection.zip

Function Syntax

node-set set:intersection(node-set, node-set)

Template Syntax

<xsl:call-template name="set:intersection">
   <xsl:with-param name="nodes1" select="node-set" />
   <xsl:with-param name="nodes2" select="node-set" />
</xsl:call-template>

The set:intersection function returns a node set comprising the nodes that are within both the node sets passed as arguments to it.

The set:intersection template applies templates to these nodes in set:intersection mode. By default, the nodes are copied by this template, so that a result tree fragment consisting of the nodes is returned.

An implementation of this extension function in the EXSLT set namespace must conform to the behaviour described in this document.
