Here is a stylesheet that you could include

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   version="1.0">

<xsl:template name="get-minimum">
   <xsl:param name="nodes" />
   <xsl:param name="current-minimum" select="number($nodes[1])" />
   <xsl:variable name="head" select="$nodes[1]" />
   <xsl:variable name="tail" select="$nodes[position() &gt; 1]" />
   <xsl:choose>
     <xsl:when test="$tail">
       <xsl:call-template name="get-minimum">
         <xsl:with-param name="nodes" select="$tail" />
         <xsl:with-param name="current-minimum">
           <xsl:choose>
             <xsl:when test="$current-minimum &lt; $head">
               <xsl:value-of select="$current-minimum" />
             </xsl:when>
             <xsl:otherwise>
               <xsl:value-of select="$head" />
             </xsl:otherwise>
           </xsl:choose>
         </xsl:with-param>
       </xsl:call-template>
     </xsl:when>
     <xsl:otherwise>
       <xsl:value-of select="$current-minimum" />
     </xsl:otherwise>
   </xsl:choose>
</xsl:template>

</xsl:stylesheet>

Then where you want to find the minimum you do e.g.
   <xsl:call-template name="get-mininum">
     <xsl:with-param name="nodes" select="key('RouterList',Supplier)" />
   </xsl:call-template>
