[xsl] Reference to other node

["alexandre bord" <alexandre.bord@xxxxxxxxxx>]

How could i better do that ?  :

<fo:block>
<xsl:variable name="id-found"><xsl:for-each 
select="//GrilleSimple[@Nom=$name-to-find]">
   <xsl:value-of select="generate-id()" /></xsl:for-each></xsl:variable>
               This is on page    <fo:page-number-citation 
ref-id="{$id-found}" />
</fo:block>


* name-to-find is a variable
* xsl:for-each returns only one node

Thanks a lot.
Alexandre
