possible usage of variables

2005-05-11 14:18:35
Hi all,

I have the following snippet of an XSL file

<xsl:template match="page">

<page>

<xsl:apply-templates/>

</page>

</xsl:template>
 
<xsl:template match="chunk">                          
            

<xsl:choose>

<xsl:when test="@requiredknowledge= 
number(preceding::chunk_name1_knowledge) "> 

 <xsl:copy-of select="."/> 

</xsl:when>
<xsl:otherwise>
<p> you do not have enough knowledge </p>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="text()"> <!-- do nothing -->
</xsl:template>
</xsl:stylesheet>


The problem now that I want to iterate the <xsl:when>
condition because I have got in the xml resource
chunk_name1_knowledge, chunk_name2_knowledge, 
chunk_name3_knowledge, 
chunk_name4_knowledge, etc.
 
Is there away to make
"preceding::chunk_name1_knowledge" variable i.e. 
"preceding::chunk_name{variable}_knowledge" 
 
Many thanks,
Fadi
