Or:

<xsl:template match="/info">
  <results>
    <xsl:for-each select='mytag'>
      <myelement duration='1'>
        <xsl:copy-of select='@duration[normalize-space()]'/>
      </myelement>
    </xsl:for-each>
  </results>
</xsl:template>

Take your pick: clarity vs. succinctness.

Cheers,
Wendell
