Re: Re: Adjusting sorted list

I've been playing with this idea and have created an interesting side
effect.

Using source:
<root>
	<a>
	    <b val="4">four</b>
	    <b val="9">nine</b>
	    <b val="6">six</b>
	    <b val="1">one</b>
	    <b val="8">eight</b>
	    <b val="6">six</b>
	    <b val="4">four</b>
	    <b val="7">seven</b>
	</a>
	<a>
	    <b val="9">nine</b>
	    <b val="5">five</b>
	    <b val="5">five</b>
	</a>
</root>

And style sheet:
<xsl:stylesheet version="1.0" 
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 
 <xsl:key name="kRanking" match="b" use="@val"/>
 
  <xsl:template match="/root/a">
    <a>
     <xsl:for-each select="b[generate-id() 
                              = 
                               generate-id(key('kRanking',@val)[1])
                               ]">
       <xsl:sort select="@val" data-type="number"/>
       
       <xsl:variable name="vPos" select="position()"/>
       
       <xsl:for-each select="key('kRanking',@val)">
         <b rank="{$vPos}">
           <xsl:value-of select="."/>
         </b>
       
       </xsl:for-each>
     </xsl:for-each>
    </a>
  </xsl:template>
</xsl:stylesheet>

I now get:
<a>
	<b rank="1">one</b>
	<b rank="2">four</b>
	<b rank="2">four</b>
	<b rank="3">six</b>
	<b rank="3">six</b>
	<b rank="4">seven</b>
	<b rank="5">eight</b>
	<b rank="6">nine</b>
	<b rank="6">nine</b>
</a>
<a>
	<b rank="1">five</b>
	<b rank="1">five</b>
</a>

What have I done???
