RE: Finding min and max

Hi there,

I already read the the way how to find the min and max node of an element.
The difference for my stylesheet is that my element consists of two values.
I would need the smallest value of the number with the leading 35. So it has
to be something with substring-before(.,' ') as I tried below, to get the
first part of the element.   

The values look like this:
<gml>3569875,45 5896534,23/>gml>
<gml>3552365,56 583256975,56/>gml>

I tried the version with the recursive template, but it didn't work out.
My code looks like that:

<xsl:template name="minimum_x">
  <xsl:param name="nodes" />
  <xsl:param name="min_temp" select="0"/>
     <xsl:choose>
        <xsl:when test="$nodes" >
         <xsl:variable name="min-so-far">
           <xsl:call-template name="minimum_x">
             <xsl:with-param name="nodes" select="$nodes[position() != 1]" />
             <xsl:with-param name="min_temp" 
select="substring-before($nodes[1],'
')"/>
          </xsl:call-template>
        </xsl:variable>
        <xsl:choose>
          <xsl:when test="$min-so-far &lt; .">
            <xsl:value-of select="$min-so-far" />
          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="." />
          </xsl:otherwise>
        </xsl:choose>
     </xsl:when>                        
  </xsl:choose>
</xsl:template>                 

any help will be appreciated
