RE: [xsl] Performance with grouping

["Michael Kay" <michael.h.kay@xxxxxxxxxxxx>]

The following should give the right result and adequate performance:

<xsl:variable name="first" select="/RESPONSES/RESPONSE[1]"/>

<xsl:template match="RESPONSES">
 <residents>
  <xsl:apply-templates/>
 </residents>
</xsl:template>

<xsl:template match="RESPONSE[1]"/>

<xsl:template match="RESPONSE">
  <resident>
  <xsl:for-each select="*">
    <xsl:element name="{$first/*[name()=name(current())]}">
      <xsl:value-of select="."/>
    </xsl:element>
  </xsl:for-each>
  </resident>
</xsl:template>

Not tested.
