iterate through attribute

Hello xsl-list,

<root>
  <option a1="1" a2="2" a3="4" ... a50="50"/>
</root>

What a good way to iterate through the attributes?


<xsl:for-each select="???">  <!-- a1 to a50 -->

<xsl:???/> <!-- gives name of attribute -->
<xsl:value-of select="???"/>   <!-- gives value of attribute -->

</xsl:for-each>
