Re: [xsl] using str:tokenize named template results

["vwiswell" <vwiswell@xxxxxxxxxxx>]

David and Michael, thank you both for your responses. I added a global 
variable 'root', as suggested and ended up with this:

<xsl:template name="buildTable">
  <xsl:param name="tokens"/>
  <xsl:variable name="ns" select="msxsl:node-set($tokens)"/>
  <xsl:for-each select="$ns/token">
    <p>token: <xsl:value-of select="." /></p>
      <xsl:for-each select="$root//city[. = $ns/token]">
      <xsl:sort select="city"/>
     <p>city: <xsl:value-of select="." /></p>
     </xsl:for-each>
 </xsl:for-each>
</xsl:template>

The tokens in this case are: A City, B City, C City

My output looks like this:

token: A City
city: A City
city: A City
city: A City
token: B City
city: A City
city: A City
city: A City
token: C City
city: A City
city: A City
city: A City

It looks like the token value here

   <xsl:for-each select="$root//city[. = $ns/token]">

never gets beyond the first value, although it is looping through the 
correct number of times (3). Do I need to qualify $ns/token somehow?

Thanks for the tip about text(). I will keep its use to a minimum :)
