EXSLT - math:min

Version: 1
Status: new
Function Package: math.min.zip

Function Syntax

number math:min(node-set)

Template Syntax

<xsl:call-template name="math:min">
   <xsl:with-param name="nodes" select="node-set" />
</xsl:call-template>

The math:min function returns the minimum, for each node in the argument node-set, of the result of converting the string-values of the node to a number using the number function. The numbers are compared as with the < operator. If the node set is empty, NaN is returned.

The math:min template returns a result tree fragment whose string value is the result of turning the number returned by the function into a string.

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