thx for reply,
here is my working code:

<xsl:variable name="dfile" select="document($datafile)"/>
<xsl:key name="pagename" match="siteinfo/pages/page" use="name"/>

<xsl:for-each 
select="document($categoryfile)//categories/category[visible!='off' and 
id!=0 and member='off']">
  <xsl:variable name="catname" select="catname"/>
  <xsl:variable name="catid" select="id"/>
  <xsl:variable name="pagename" select="$dfile[key('pagename', $catname)]"/>

  <xsl:variable name="pageid">
   <xsl:for-each 
select="document($datafile)//siteinfo/pages/page[category=$catid]">
     <xsl:variable name="pid" select="id"/>
     <xsl:value-of select="id"/>
   </xsl:for-each>
  </xsl:variable>

   <xsl:choose>
   <!-- the 'test=' expression converts the returned nodeset of xsl:key to a 
boolean value, therefore it can be requested for true() or false() -->
   <xsl:when test="$pagename">
    ,"<xsl:value-of select="$nbsp"/><xsl:value-of 
select="$not"/><xsl:value-of select="$nbsp"/><xsl:value-of 
select="$catname"/>","default.asp?id=<xsl:value-of 
select="$pageid"/>&amp;mnu=<xsl:value-of 
select="$pageid"/>","","<xsl:value-of select="$catname"/>",0
   </xsl:when>
   <xsl:otherwise>
    ,"<xsl:value-of select="$nbsp"/><xsl:value-of 
select="$not"/><xsl:value-of select="$nbsp"/><xsl:value-of 
select="$catname"/><xsl:value-of select="$nbsp"/>","show-menu=<xsl:value-of 
select="$catname"/>",,"",1
   </xsl:otherwise>
  </xsl:choose>
</xsl:for-each>
