Re: [xsl] How best to use recursion/call-templates?

[Peter Davis <pdavis152 at attbi dot com>]

You can use the key() function to output a <span> for each unique account 
number, and also to select all the other accounts with that same number:

<xsl:key name="row" match="row" use="account"/>
<xsl:template match="row">
  <xsl:if test="count(key('row', account)[1] | .) = 1">
    <span>
      <xsl:value-of select="account"/>
      <xsl:for-each select="key('row', account)">
        <a><xsl:value-of select="name"/></a>
      </xsl:for-each>
    </span>
  </xsl:if>
</xsl:template>

There shouldn't be any need for a recursive template (or even a named 
template).
