I have this xml code

<?xml version="1.0"?>
<products>
  <product id="p1" name="Delta" price="3250" stock="4" country="Denmark"/>
  <product id="p2" name="Golf" price="1000" stock="5" country="Germany"/>
  <product id="p3" name="Alpha" price="1200" stock="19" country="Germany"/>
  <product id="p4" name="Foxtrot" price="1500" stock="5" country="Australia"/>
  <product id="p5" name="Tango" price="1225" stock="3" country="Japan"/>
</products>

I want to grouped it depend on "country", by using xslt stylesheet

<?xml version="1.0"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://ift.tt/tCZ8VR">
  <xsl:output indent="yes"/>
  <xsl:template match="/">
    <products>
      <xsl:for-each-group select="products/product" group-by="@country">
        <xsl:comment>
          <xsl:value-of select="current-grouping-key()"/>
        </xsl:comment>
        <xsl:for-each select="current-group()">
          <xsl:copy-of select="."/>
        </xsl:for-each>
      </xsl:for-each-group>
    </products>
  </xsl:template>
</xsl:stylesheet>

I want to see the resulte on Firefox, the result is

Error during XSLT transformation: XSLT transformation failed.

instead of the deserve result, my question is why firefox does not display the result?
