<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:template match="data">
    <xsl:variable name="i" select="2"/>
    <xsl:variable name="item" select="concat( 'item', $i)"/>
    <xsl:apply-templates select="*[ local-name() = $item ]"/>
  </xsl:template>

  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

But I think there is nothing wrong with using <xsl:choose> here.
