My XML file is:
<ALMACEN>
<ARTICULO>
  <DESCRIPCION_CORTA>chuletas cerdo</DESCRIPCION_CORTA>
  <DESCRIPCION_LARGA>chuletas cerdo extra</DESCRIPCION_LARGA>
  <NOMBRE_FAMILIA>alimentacion</NOMBRE_FAMILIA>
  <NOMBRE_SUBFAMILIA>carnes</NOMBRE_SUBFAMILIA>
</ARTICULO>
<ARTICULO>
  <DESCRIPCION_CORTA>chuletas marrano</DESCRIPCION_CORTA>
  <DESCRIPCION_LARGA>chuletas marrano extra</DESCRIPCION_LARGA>
  <NOMBRE_FAMILIA>alimentacion</NOMBRE_FAMILIA>
  <NOMBRE_SUBFAMILIA>verduras</NOMBRE_SUBFAMILIA>
</ARTICULO>
<ALMACEN>

And I want to show this information sorted in a HTML table. I perform this 
with the code:
<xsl:template match="/ALMACEN">
<xsl:for-each select="ARTICULO">
  <xsl:sort select="NOMBRE_FAMILIA"/>
  <xsl:sort select="NOMBRE_SUBFAMILIA"/>
  <xsl:sort select="DESCRIPCION_CORTA"/>
  ...
</xsl:for-each>
</xsl:template>

My problem is that I have to compare each 'ARTICULO' with the following 
'ARTICULO', but once they are sorted.
For this, I think the best solution is to store in a variable all the nodes 
'ARTICULO', sort them, and compare each of them with the following.

The variable is formed as:
<xsl:variable name="nodos" select="//ARTICULO"/>

I hope you have enought information with it, otherwise I´ll be pleased to 
give it to you.

Thanks friend!
